Image technology for human recognitionAbstractToday's society is a society with rapid development of science and technology andeconomy,and the level of image processing technology is also forging ahead.With theprogress of science and technology and the improvement of life modernization,theapplication of image technology has become more mature.When encountering dangeroussituations or natural disasters,it will be the future development direction of image detectiontechnology to use image processing technology to improve the accuracy of image detectionand quickly and effectively identify human beings.There are many difficulties in detectingthe human body and silhouette with image technology,including the diversity of human types,the difference in clothing,the weather factors,the Angle changes and the differentbackgrounds.The text analyzes some basic concepts and algorithms of image segmentationand target contour extraction,and then elaborates the human method in the detection andrecognition domain in video surveillance in detail.After the two steps of single gaussianbackground modeling and target detection,the system design is analyzed and simulated byMATLAB.Keywords:背景差分；运动目标检测；图像分割；目标提取；MATLAB
