Rate-Complexity-Distortion Optimization for Quadtree-Based DCT Coding
In this paper, we study rate-complexity-distortion (R-C-D) tradeoffs for video coding, where we focus on the complexity of computing the inverse DCT. A quadtree coding approach is...

Image Coding on Quincunx Lattice with Adaptive Lifting and Interpolation
Considering that quincunx lattice is a more efficient spatial sampling scheme than square lattice, we investigate a new approach of image coding for quincunx sample arrangement. T...

Implementation of message-passing algorithms for the acquisition of spreading codes
A new technique to acquire pseudo-noise (PN) sequences has been recently proposed in [1] and [2]. It is based on the paradigm of iterative Message Passing (iMP) to be run on loopy...
