APPARATUS AND METHOD FOR DYNAMIC COMPRESSION

摘要

PURPOSE: An apparatus and a method for dynamic compression are provided to improve a compression rate by compressing an interested object region and the rest regions at different compression rates by separating and extracting an inputted image according to the user interest object region. CONSTITUTION: An interface unit(110) designates an interest object area on an image, and a matting unit(120) designates the interest object area designated through the interface as view. The matting unit designates a region except the interest object region as a background. According to a matting result, a compression applying unit(130) compresses an appointed area at different compression rates.
