Texture analysis using adaptive biorthogonal wavelet packets
We discuss the use of adaptive biorthogonal wavelet packet bases in a probabilistic approach to texture analysis, thus combining the advantages of biorthogonal wavelets (FIR, line...

Rate-distortion optimized image compression using wedgelets
Most wavelet-based image coders fail to model the joint coherent behavior of wavelet coefficients near edges. Wedgelets offer a convenient parameterization for the edges in an ima...

Bayesian high-resolution reconstruction of low-resolution compressed video
A method for simultaneously estimating the high-resolution frames and the corresponding motion field from a compressed low-resolution video sequence is presented. The algorithm in...

A rate-distortion optimal video pre-processing algorithm
Pre-processing algorithms improve the quality of a compression system by removing unimportant data before encoding. This enhances both the visual quality and coding efficiency of ...

Deformable Matching of Hand Shapes for User Verification
Wepresent a method for personal authentication based on deformable matching of hand shapes. Authentication systems are already employed in domains that require some sort of user v...
