APPARATUS FOR SEPARATING FOREGROUND FROM BACK GROUND AND METHOD THEREOF

摘要

PURPOSE: An apparatus for separating a foreground from a back ground and a method thereof are provided to enhance the foreground/background separation performance by accurately performing a codeword modeling. CONSTITUTION: A background model generator(300) generates a codebook for foreground/background separation, and includes a codeword generation block(301) and codeword rearrangement block(302). The codebook includes plural codewords, and a foreground/background separation unit(350) separates the foreground from the background by using the generated codebook. A foreground/background decision unit(351) includes a post-processing block(352).
