In this paper, an image coding algorithm based on a rate-distortion optimized wavelet-based contourlet transform (WBCT) decomposition and on an improved listless block-partitioning coding scheme which quantizes each subband separately is proposed. The Wavelet-Based Contourlet Transform (WBCT) can provide optimally sparse representation of objects with singularities along c2 edges. Instead of lists,...
In this paper, we propose a orthonormal finite ridge let packet transform. An image coding algorithm based on a rate-distortion optimized orthonormal finite ridge let packet transform (OFRPT) decomposition and on an improved listless block-partitioning coding scheme which quantizes each sub band separately is proposed.

The ridge let transform can provide optimally sparse representation of objects with singularities along straight edges and the orthonormal finite...

In this paper, an image coding algorithm based on a rate-distortion optimized orthonormal finite ridgelet transform (OFRIT) decomposition and on a block-partitioning coding scheme which quantizes each subband separately is proposed. In this way, our algorithm naturally overcomes the difficulty in defining parent-child relationships for wavelet-based ridgelet subbands, which exists in the zerotree...
