Abstract

We propose a new region extraction and image composition method with chromakey using a two-tone striped background and active contour models.A problem with using conventional chromakey techniques is that if objects have the same color,they appear to be part of the background.To improve the clarity of the image,we utilized adjacency conditions between two-tone striped areas on the background,and extracted foreground regions whose colors are same as those of the background.In addition,by using active contour models for the extraction result,we significantly improved the accuracy of the extraction.The validity of our method was shown through experiments.
