Title The research of infrared motion detection algorithm
Abstract
The use of infrared imaging for automatic target detection, recognition and tracking is the main direction of development of modern military weapons and equipment. The infrared low SNR target detection problem is one of the key technologies in military weapon systems. At the same time it has been a hot research field in optics and image.
The theme of this article is the target image detection of the infrared motion .The second chapter is the infrared image histogram analysis. The third chapter is the infrared image preprocessing, analysis simulation of the linear low-pass smoothing filter and median filter to achieve target, then split to extract the target. In the fourth chapter is the image segmentation based on the Threshold method, analysis and simulation of bimodal method, maximum between-class variance method based on two-dimensional maximum entropy method. Roberts, Sobel, Prewitt, Canny, such as four kinds of edge detection operators and then in the fifth chapter is the study based on edge detection image segmentation method, analysis, and programming the simulation results of the assessment. The article also gives the target detection methods, procedures, flowcharts, as well as simulated images, easy to understand and verify.
