Apparatus and method for encoding depth image by skipping discrete cosine transform (dct), and apparatus and method for decoding depth image by skipping dct

摘要

An apparatus and method for encoding an image by skipping discrete cosine transform (DCT), and an apparatus and method for decoding an image by skipping the DCT. An image encoding apparatus may classify residual data into groups, and may encode the residual data using a representative value of each of the groups and group identification information that is used to identify the groups.
