POST FILTER, A LOOP FILTER, A VIDEO DATA ENCODING OR DECODING DEVICE AND AN OPERATION METHOD THEREOF CAPABLE OF IMPROVING PRESSURE RATES

摘要

PURPOSE: A post filter, a loop filter, a video data encoding or decoding device and an operation method thereof are provided to improve the quality of a depth image in an image pressure system.;CONSTITUTION: A post filter(100) inserted into a video data encoding device includes an input unit(110) and a processing unit(120). The input unit receives a pressure image for a depth image inputted to the video data encoding device. The pressure image includes a plurality of slices. The processing unit determines optical filter parameters for executing an intension of boundary line for an image profile.;COPYRIGHT KIPO 2013;[Reference numerals] (101) Intra prediction unit; (102) Movement estimation and compensation unit; (104) Conversion and quantization unit; (105) Inverse quantization and inverse conversion unit; (107) Entropy coding unit; (108) Picture server; (110) Input unit; (120) Processing unit; (130) Output unit; (AA) Input images; (BB) Bit-stream; (CC) Compressed images; (DD) Filter parameters
