| 摘 要： | 提出了一种在单一背景下不需要用户介入的全自动人物精确提取方法.该方法首先用边缘检测和单色背景颜色特征相结合自动获取人物的大体边缘,然后按人体形态分区域,针对不同区域用基于当前像素颜色与背景颜色的距离比来精确获取人体的边缘.另外,该方法对于人体服装和背景颜色相近时的图片也能够取得很好的精细分割效果.

| Abstract: | An automatic method of human body matting against a constant colored background was presented.First,edge detecting and the background features were used to estimate the imprecise region of the body,and then the region was divided into different parts using the body shape features.Based on the information of the different regions,the body edge was matted by using the distance proportion of the color between the current pixel and background.In addition,the method could effectively mate body edge from the imag... |
