Title:
APPARATUS AND METHOD FOR IMAGE ENCODING OR DECODING
Document Type and Number:
WIPO Patent Application WO/2019/078693
Kind Code:
A1
Abstract:
The present invention relates to image encoding for efficient encoding of an image or to image decoding. More specifically, the present invention relates to scanning techniques performed on (quantized) transform coefficients. According to scanning techniques of the present disclosure, a scan pattern used for scanning quantized transform coefficients associated with a current block no longer has a dependency on a previously decoded data block (i.e., a neighboring block of a current block). Therefore, the present invention solves the problem of parsing delay of syntax elements relating to coefficients, which is generated by associating a scan pattern with an intra prediction mode.
