Explicit capacity-achieving list-decodable codes
For every 0 < R < 1 and > 0, we present an explicit construction of error-correcting codes of rate R that can be list decoded in polynomial time up to a fraction (1 - R ...

DCT Based High Quality Image Compression
Abstract. DCT based image compression using blocks of size 32x32 is considered. An effective method of bit-plane coding of quantized DCT coefficients is proposed. Parameters of pos...

Low-Complexity Adaptive Block-Size Transform Based on Extended Transforms
In this paper, a low-complexity 8x8/4x4 Adaptive Blocksize Transform (ABT) scheme is tentatively proposed for the Chinese Audio and Video coding Standard (AVS)1 . In the proposed ...
