More Information
Summary:The present invention relates to a method for performing an adaptive deblocking filter using a quantization parameter for each image block unit at a macroblock boundary including an intra macroblock, and to a device thereof. The filter and a filtering method according to the present invention have an effect of improving the compression ratio in the field of high-resolution and high-definition video image compression. 본 발명은 인트라 매크로 블록이 포함된 매크로 블록 경계에서 영상 블록 단위 양자화 파라미터를 이용하여 적응적 디블록킹 필터를 수행하는 방법 및 그 장치에 관한 것이다. 본 발명에 따른 필터 및 필터링 방법은 높은 해상도 및 고화질 비디오 영상 압축 분야에서 압축률을 향상시키는 효과가 있다.
