Abstract
Two enhanced subband coding schemes using a regularized image restoration t echnique are proposed: the first controls the global regularity of the deco mpressed image, the second extends the first approach at each decomposition level. The quantization scheme incorporates scalar quantization (SQ) and p yramidal lattice vector quantization (VQ) with both optimal bit and quantiz er allocation. Experimental results show that both the block effect due to VQ and the quantization noise are significantly reduced.
