Title:
IMAGE ENCODING/DECODING METHOD FOR RATE-DISTORTION OPTIMIZATION AND DEVICE FOR PERFORMING SAME
Document Type and Number:
WIPO Patent Application WO/2013/032312
Kind Code:
A3
Abstract:
Disclosed are an image encoding/decoding method for rate-distortion optimization and a device for performing the same. A macroblock to be encoded is provided, a prediction macroblock is generated by executing either inter prediction or intra prediction, a residual prediction block is generated on the basis of the generated prediction macroblock and the provided macroblock, and the residual prediction block is transformed by applying one of a plurality of predetermined transform matrices to the generated residual prediction block. Accordingly, rate-distortion can be optimized, and image quality can be enhanced.
