Title:
METHOD AND APPARATUS FOR ENCODING/DECODING IMAGES CONSIDERING LOW FREQUENCY COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2011/037337
Kind Code:
A2
Abstract:
The present invention relates to a method and an apparatus for encoding/decoding images considering low frequency components. The present invention provides an image encoding method comprising the steps of: predicting and encoding a present block to generate encoded image data and a recovered block; and generating encoded low frequency data by encoding only low frequency components of an error block generated through the subtraction of the present block and the recovered block. The present invention can reduce the block effect due to the conversion and the quantization and can improve the compression efficiency by encoding motion pictures considering the low frequency components.
