Human-area segmentation is a major issue in video surveillance. Many existing methods estimate individual human areas from the foreground area obtained by background subtraction, but the effects of camera movement can make it difficult to obtain a background image. We have achieved human-area segmentation requiring no background image by using chamfer matching to match the results of human detection using Real AdaBoost with silhouette images. Although accuracy in chamfer matching drops as the number of templates increases, the proposed method enables segmentation accuracy to be improved by selecting silhouette images similar to the matching target beforehand based on response values from weak classifiers in Real AdaBoost.
