Aiming at virtual machine load balance evaluation, this paper proposes an evaluation algorithm based on quadratic equilibrium entropy. Firstly, we propose the computational methods for linear equilibrium and quadratic equilibrium entropy. Secondly, we analyze the physical meanings of linear equilibrium and quadratic equilibrium, and analyze their application method in virtual machine load balance. Finally, we prove our scheme by giving experimental results.

For the phenomenon of low image contrast usually appearing in scanning electron microscope images, a low contrast microscopic image enhancement algorithm based on multi-technology fusion was proposed, in which the high frequency and low frequency components of images are separated to avoid the increased image noise, while the images was strengthened. Furthermore, the low contrast microscopic image enhancement was realized combining with Sobel operator, LoG operator and improved contrast limited adaptive histogram equalization method. Experimental results show that the proposed method highlights the image edges and details effectively, which can expand the dynamic grayscale range of image, increase the image contrast and entropy so lay the foundation for the microscopic image analysis and identification.
