Face Mask Detection Using Hybrid Approach

SummaryAccurate prediction of the solubility of chemical substances in solvents remains a challenge. The sparsity of high-quality solubility data is recognized as the biggest hurdle in the development of robust data-driven methods for practical use. Nonetheless, the effects of the quality and quantity of data on aqueous solubility predictions have not yet been scrutinized. In this study, the roles of the size and the quality of data sets on the performances of the solubility prediction models are unraveled, and the concepts of actual and observed performances are introduced. In an effort to curtail the gap between actual and observed performances, a quality-oriented data selection method, which evaluates the quality of data and extracts the most accurate part of it through statistical validation, is designed. Applying this method on the largest publicly available solubility database and using a consensus machine learning approach, a top-performing solubility prediction model is achieved.

The Face Mask Wearing Image Dataset is a comprehensive collection of images aimed at facilitating research in the domain of face mask detection and classification. This dataset consists of 24,916 images, carefully categorized into two main folders: “Correct” and “Incorrect” representing instances of face masks being worn properly and improperly, respectively. Each folder is further divided into four subfolders, each denoting a specific type of face mask - Bandana, Cotton, N95, and Surgical. In the “Correct” folder, images depict individuals correctly wearing their respective face masks, while the “Incorrect” folder contains images of improper face mask usage. To capture variations in face mask application across different demographics, such as age and gender, each subfolder also includes three additional subfolders - Child, Male, and Female. The dataset's diverse content encompasses different face mask types, covering bandana-style, cloth, N95 respirators, and surgical masks, across various age groups and genders. This design ensures a comprehensive representation of real-world scenarios, enabling the evaluation of machine learning algorithms for face mask detection and classification. Researchers can leverage this dataset to develop and assess models that can accurately identify and distinguish between correct and incorrect face mask usage. By contributing to the advancement of face mask detection technologies, this dataset further supports public health initiatives and encourages proper mask-wearing behavior to mitigate the spread of infectious diseases, particularly during times of heightened health concerns such as the COVID-19 pandemic.

In this paper, we investigate the problem of face mask compliance classification in response to the Corona Virus Disease (COVID-19) pandemic. Since the start of the pandemic, many governments and businesses have been continually updating policies to help slow the spread of the virus, including requiring face masks to use many public and private services. In response to these policies, many researchers have developed new face detection and recognition techniques for masked faces. Many of the developed approaches proposed to address the problem of masked face detection have been relatively successful. However, these approaches almost exclusively focus on detecting the presence or absence of someone wearing a face mask. It is understood and broadly discussed in various reports and the media that there are people not always following the suggested guidelines provided by public health authorities for wearing face masks, which include ensuring the face mask properly covers the nose and mouth. To date, very few research publications exist that investigate the capability of modern classification algorithms to efficiently distinguish between masked faces in the visible band that are either compliant or non-compliant with the suggested guidelines. Furthermore, to the best of our knowledge, there is no publication in the open literature that focuses on the investigation of face mask classification in the thermal band. As thermal sensors continue to improve in quality and decrease in cost, surveillance applications using thermal imagery are expected to continue to grow and benefit those organizations considering the automation of face mask detection and compliance. In this study, we propose an investigation on face mask compliance in both the thermal and visible bands. It is composed of the following salient steps; (1) the creation of a multi-spectral masked face database from subjects wearing or not wearing face masks, (2) the augmentation of the generated database with synthetic face masks to simulate two different levels of non-compliant wearing of face masks, and (3) the assessment of a variety of CNN architectures on the previous augmented database to investigate any differences between classifying thermal and visible masked faces. Experimental results show that face mask compliance classification in both studied bands yield a classification accuracy that reaches 100% for most models studied, when experimenting on frontal face images captured at short distances with adequate illumination.KeywordsFace masksCOVID-19PandemicFace mask classificationDeep learningMask complianceThermal imagingMulti-spectral Imaging

Face masks alter the speakers' voice, as their intrinsic properties provide them with acoustic absorption capabilities. Hence, face masks act as filters to the human voice. This work focuses on the automatic detection of face masks from speech signals, emphasising on a previous work claiming that face masks attenuate frequencies above 1 kHz. We compare a paralinguistics-based and a spectrograms-based approach for the task at hand. While the former extracts paralinguistic features from filtered versions of the original speech samples, the latter exploits the spectrogram representations of the speech samples containing specific ranges of frequencies. The machine learning techniques investigated for the paralinguistics-based approach include Support Vector Machines (SVM), and a Multi-Layer Perceptron (MLP). For the spectrograms-based approach, we use a Convolutional Neural Network (CNN). Our experiments are conducted on the Mask Augsburg Speech Corpus (MASC), released for the Interspeech 2020 Computational Paralinguistics Challenge (COMPARE). The best performances on the test set from the paralinguistic analysis are obtained using the high-pass filtered versions of the original speech samples. Nonetheless, the highest Unweighted Average Recall (UAR) on the test set is obtained when exploiting the spectrograms with frequency content below 1 kHz.

An outbreak of the coronavirus (Covid-19) has spread around the world, causing widespread health concerns. The pandemic's reach has spread to nearly every development sector. There have been numerous steps attempted to prevent the in areas where Covid-19 has spread, wearing a face mask is mandatory. The Covid-19 transmission could not have been controlled without it. To top it all off, seeks to detect finegrained wearing states of the face mask: make sure your face is covered with the right mask Without a disguise. There are two very difficult jobs in our job: first, because of an online market for augmented data sets as well as large-scale training datasets. A face mask identification app for mobile devices is presented in this paper. In its entirety, Cloud-based machine learning technology known as Google Cloud ML API automates the process using TensorFlow files to train the model The ML's effectiveness is demonstrated in this research model. The progress of cloud technology is also examined in this paper. Over traditional coding methods, machine learning is becoming increasingly popular.

A new and deadly virus known as SARS-CoV-2, which is responsible for the coronavirus disease (COVID-19), is spreading rapidly around the world causing more than 3 million deaths. Hence, there is an urgent need to find new and innovative ways to reduce the likelihood of infection. One of the most common ways of catching the virus is by being in contact with droplets delivered by a sick person. The risk can be reduced by wearing a face mask as suggested by the World Health Organization (WHO), especially in closed environments such as classrooms, hospitals, and supermarkets. However, people hesitate to use a face mask leading to an increase in the risk of spreading the disease, moreover when the face mask is used, sometimes it is worn in the wrong way. In this work, an autonomic face mask detection system with deep learning and powered by the image tracking technique used for the augmented reality development is proposed as a mechanism to request the correct use of face masks to grant access to people to critical areas. To achieve this, a machine learning model based on Convolutional Neural Networks was built on top of an IoT framework to enforce the correct use of the face mask in required areas as it is requested by law in some regions.

The finish of 2019 saw the event of corona virus. It has continued to cause havoc for many people and organizations well into 2022. As the globe recovers from the epidemic and prepares to resume normal operations, a wave of pressure is felt by all individuals, especially those that will continue taking face to face. Studies have demonstrated that conveying a cover significantly decreases the shot at irresistible specialist transmission still as gives a method of assurance. To relieve this drawback, this undertaking and innovation hold the key here for goal this issue. It presents a Deep Learning based generally framework that will observe occasions at any place facial coverings aren't utilized as expected. The face mask helps us from effecting various diseases to us. We all know the importance of face masks in these recent times due to this pandemic situation. The rapid decrease of covid cases leads to the ignorance of face masks due to that many of the people are affected again and the second wave of virus spread among people. People started taking precautions and again cases decreased, then now also people started ignoring the face masks. There are a lot of basic gears that will be needed to fight the Corona infection. Face Mask is one of the most fundamental. Initially, everyone was not compelled to wear a facial covering, but as time has gone, researchers and doctors have suggested that everyone does so. In the general public presently, which can be utilized for different applications like at the air terminal, medical clinics, workplaces, schools, and so on. This framework can be critical at air terminals to identify voyagers whether or not they are wearing a mask. We are creating a system that will detect masks. Due to the ignorance of masks and taking precautions, again the third wave is going to start. Now in recent times, a new variant of the covid virus came out called “Omicron”. This system can detect whether someone is wearing a mask or not, and it may be deployed anyplace, such as a CCTV or security system. The recent research helps us to understand how the working of previous face mask detection systems. We see there is a lot of defects, which we are going to solve in our face mask detection system.

The world has faced a massive health emergency due to the prompt transmission of corona-virus (COVID-19) over the last two years. Since there is no specific treatment for COVID-19, infections have to be limited through prevention methods. Wearing a face mask is an effective preventive method in public areas. However, it is impractical to manually implement such regulations on big locations and trace any infractions. Automatic face mask detection facilitated by deep learning techniques provides a better alternative to this. This research introduced an automatic face detection system using ASUS Tinker single-board computer and MobileNetV2 model. As most of the publicly available face mask detection dataset was artificially generated, in this work, a real face mask detection dataset was first created consisting of a total of 300 images. The ASUS Tinker board’s model training and testing performance and training time have been assessed for this dataset and a publicly accessible dataset of 1376 images. The recommended system reached 99% of test accuracy, precision, recall, and f1-score for the newly collected dataset and 100% of test accuracy, precision, recall, and f1-score for the publicly available dataset.

COVID-19 pandemic has led to an international health emergency the WHO considers wearing a face mask an appropriate form of public health protection. This work will describe a face mask identification model that incorporates both deep and traditional machine learning techniques. Parts of the suggested model can be divided into two. Using Resnet50, the initial part of the system is set up for feature extraction. The second component classifies face masks using decision trees, support vector machines (SVMs), and the ensemble approach. The research will focus on three face-masked datasets. The Real-World Masked Face Dataset Includes three datasets: real-world masked faces, simulated faces, and wild faces (LFW). 99.64% of RMFD's SVM classifier is accurate throughout testing.. It achieved a 99.49% accuracy rate in SMFD and a 100% accuracy rate in LFW.

The face mask is the first line of defense against infectious particulates and droplets that may cause illness. Currently in the Philippines, the wearing of face mask is compulsory whenever citizens leave their residences as mandated by the government to mitigate the spread of COVID-19. The wearing of face masks has become a new normal among Filipinos. This created market opportunities for different types which became commonly and immediately available for purchase. This study aimed to differentiate the effectiveness of locally available face masks in terms of electrostatic filtration capability. Twelve different types of face masks grouped into five categories – surgical, fabric, N95 variants, foam type, and novelty type – were evaluated. Electrostatic fields were measured from each face mask including pore sizes via scanning electron microscopy. Moreover, by utilizing the estimated charge and mass of the SARS-CoV-2 virion, the transmission rate was simulated using COMSOL Multiphysics®. It was observed that face masks with negatively charged materials combined with small pore sizes afforded less particle transmission. The results of this study are of timely significance in potentially laying out public awareness in the selection and utilization of face masks that can provide foremost shielding against viral transmission.

After training 4000 epochs mAP score is 0.96. This unique approach of face mask visualization system attained noticeable output which has 96% classification and detection accuracy.

This study evaluates the predictive performance of advanced machine learning models, including DeepBoost, XGBoost, CatBoost, RF, and MLP, in estimating the Ω2, Ω4, and Ω6 parameters based on a comprehensive set of input variables. Among the models, DeepBoost consistently demonstrated the best performance across the training and testing phases. For the Ω2 prediction, DeepBoost achieved an R2 of 0.974 and accuracy of 99.895% in the training phase, with corresponding values of 0.971 and 99.902% in the testing phase. In comparison, XGBoost ranked second with an R2 of 0.929 and accuracy of 99.870% during testing. For Ω4, DeepBoost achieved a training phase R2 of 0.955 and accuracy of 99.846%, while the testing phase results included an R2 of 0.945 and accuracy of 99.951%. Similar trends were observed for Ω6, where DeepBoost obtained near-perfect training phase results (R2 = 0.997, accuracy = 99.968%) and testing phase performance (R2 = 0.994, accuracy = 99.946%). These findings are further supported by violin plots and correlation analyses, underscoring DeepBoost’s superior predictive reliability and generalization capabilities. This work highlights the importance of model selection in predictive tasks and demonstrates the potential of machine learning for capturing complex relationships in data.

In 2020, COVID has grown to be a significant public health concern. The virus's contact-transparent properties caused it to propagate quickly. Wearing a mask that stops the transmission is the most effective strategy to prevent this. The first step in lowering the danger is to wear a mask, which cuts the likelihood of contracting the infection by 70%. To resolve this problem, we need the system to keep an eye on the facial mask. This work can be facilitated by a face mask detector based on deep learning (DL) and machine learning (ML) models can make this task easier. Here, we do face mask categorization utilizing several ML and DL techniques. Here, we experimented with various methods such as CNN, Resnet50, Gabor filter, GLCM, SVM, KNN for extracting features and classifying faces with mask and without mask. From the accuracy we got for each model it says CNN performs well on the dataset we took.

According to the World Health Organization data, the global epidemic of COVID-19 has profoundly affected the world and has now infected more than eight million people worldwide. The COVID-19 epidemic forced governments worldwide to close their doors to prevent the spread of the virus. Reports indicate that wearing a facemask and maintaining public distance while at work reduces the risk of infection. CCTV cameras are installed in educational and industrial spaces, residential areas, and crowded places. However, it is difficult to physically monitor buildings to find people without masks and people who do not keep public distance, and it is challenging to monitor video footage of large buildings and find people without a facemask and social distance correction. A mixed model that uses in-depth reading and machine learning to face masks and correct public distances will help managers look after people roaming the grounds without hiding their faces and distance from the public. The supervised machine-learning algorithm will train the model with the data available online. The facemask data acquisition set contains masked and non-masked images. OpenCV will be used for real-time face recognition and social distance adjustment from live streaming videos from web-enabled videos. The Convolution Neural Network will be used to extract features from the database. After the feature removal process, the newly installed photo/video will be classified as face masked or face masked. The proposed methodology has shown that person detection, social distance, and F.I. scores approximate 91.2%, and the average F1 score is 90.79%.KeywordsFacemaskSocial distancingCNNOpenCVTensor flowYOLO
