An MRF model-based approach to the detection of rectangular shape objects in color images

Of great importance are the tasks of recognizing objects of a given shape and color on complex background in conditions of interference with high accuracy. In this regard, the development of effective algorithms for selecting objects that reduce the influence of noise component and reduce computational costs of performing operations in which the result will be suitable for subsequent analysis within the framework of the tasks being solved is an urgent task. This paper presents a model of objects and a method based on radial symmetry transformation for the problems of recognizing round-shaped colored objects in color images. Examples of such objects include the pupils of the eyes, traffic lights, car lights and light markers. The aim of the work is to increase the accuracy of detecting round-shaped colored objects in the images under interference conditions using modified radial symmetry transformation. The paper describes a model and a method for detecting objects in images, presents the results of numerical experiments that allow us to estimate the limits of applicability of the proposed method.

We present an approach for detecting and estimating the 3D poses of objects\nin images that requires only an untextured CAD model and no training phase for\nnew objects. Our approach combines Deep Learning and 3D geometry: It relies on\nan embedding of local 3D geometry to match the CAD models to the input images.\nFor points at the surface of objects, this embedding can be computed directly\nfrom the CAD model; for image locations, we learn to predict it from the image\nitself. This establishes correspondences between 3D points on the CAD model and\n2D locations of the input images. However, many of these correspondences are\nambiguous as many points may have similar local geometries. We show that we can\nuse Mask-RCNN in a class-agnostic way to detect the new objects without\nretraining and thus drastically limit the number of possible correspondences.\nWe can then robustly estimate a 3D pose from these discriminative\ncorrespondences using a RANSAC- like algorithm. We demonstrate the performance\nof this approach on the T-LESS dataset, by using a small number of objects to\nlearn the embedding and testing it on the other objects. Our experiments show\nthat our method is on par or better than previous methods.\n

Real-time object detection and ranging of multiple objects on the road are the essential tasks in the field of autonomous driving. In this paper, we introduce a system for simultaneous detection and ranging of vehicles, people, non-motor vehicles and lanes based on RGB-D images. Among them, the detection of vehicles, people and non-motor vehicles belongs to general detection task and the lane detection belongs to segmentation task. In order to improve the accuracy and speed, we use two networks to complete these two tasks. We propose a real-time synchronization method with multi-GPU, which achieves separate training and simultaneous detection of lane detectior and vehicle, people and non-motor vehicle detector. We also propose a center-selective ranging module based on binocular ranging technology to distance the detected object. The system reaches nearly 15 FPS with four 1080Ti GPUs. We construct datasets about these problems including daytime and night in which the system achieves high accuracy. A real-time test of the system on the streets of Tianjin, China has been conducted by us, it has proved that the system can be applied to actual driving.

Cloud computing infrastructures have become the de-facto platform for data driven machine learning applications. However, these centralized models of computing are unqualified for dispersed high-volume real-time edge data intensive applications such as real time object detection, where video streams may be captured at multiple geographical locations. While many recent advancements in object detection have been made using Convolutional Neural Networks, these performance improvements only focus on a single, contiguous object detection model. In this paper, we propose a distributed Edge-Cloud R-CNN pipeline. By splitting the object detection pipeline into components and dynamically distributing these components in the cloud, we can achieve optimal performance to enable real time object detection. As a proof of concept, we evaluate the performance of the proposed system on a distributed computing platform including cloud servers and edge-embedded devices for real-time object detection on live video streams.

The authors describe how to design color illumination to improve the discriminability of objects in color images. This procedure is useful in applications where the illumination can be controlled, such as inspection tasks. From the physics of color image formation, the optimal color illumination for discriminating materials is derived using a parametrically defined set of illuminants. The authors suggest how such an approach might be extended to sets of materials and more general classes of light sources. Experiments with painted color patches and live potato plantlets are used to illustrate the usefulness of actively controlling illumination color in machine vision. >
