Weighted Adaptive Lifting-Based Wavelet Transform for Image Coding
In this paper, a new weighted adaptive lifting (WAL)-based wavelet transform is presented. The proposed WAL approach is designed to solve the problems existing in the previous adap...

Image Coding Using Dual-Tree Discrete Wavelet Transform
In this paper, we explore the application of 2-D dual-tree discrete wavelet transform (DDWT), which is a directional and redundant transform, for image coding. Three methods for sp...

Recovering from Bit Errors in Scalar-Quantized Discrete Wavelet Transformed Images
In this paper we study the e ects of transmission noise on xed-length coded wavelet coe cients. We extend our previous work on maximum a posteriori detectors 1] to include interbi...

3D multiresolution context-based coding for geometry compression
In this paper, we propose a 3D geometry compression technique for densely sampled surface meshes. Based on a 3D multiresolution analysis (performed by a 3D Discrete Wavelet Transf...

Channel adapted multiple description coding scheme using wavelet transform
A challenge of image communication over unreliable channels is to achieve good compression rates and be effective in presence of channel failures. In this work we use the Multiple...
