视频序列中的一种微动目标提取与背景替换算法
AN ALGORITHM OF MICRO MOVING TARGET EXTRACTION AND BACKGROUND REPLACEMENT IN VIDEO SEQUENCES
摘要
Abstract
In order to realise the background replacement of micro moving targets in video images,there has the need to solve the problem of accurate micro moving targets extraction.In the paper we first use Adaboost classifier to train skin colour sample database to obtain the data of skin colour and non-skin colour,and determine the threshold range of skin colour,as well as get the binary image of skin colour detection. Then we fuse the binary images of skin colour detection and the binary images of micro moving targets segmented by Otsu to get the rough binary image of image sequence of micro moving targets.After that,we obtain the complete binary image templates through the treatment processes of morphology and holes filling,and at last accomplish the background replacement of video image.Simulation experiments show that the proposed algorithm can well segment the micro moving targets and realise background replacement.关键词
