Abstract

This paper presents a newmetho d for automatically extracting an object region from a photograph based upon a well-known method "Intelligent Scissors" (IS). For our application, it will be shown that (1) the cost should not be based on accumulated cost adopted by IS but rather on average cost and (2) only a fewpast pixels are needed for deciding the future route. It will be shown that our new method will be able to extract object region with a correct rate of approximately 93% if object images are well-focused.
