Adaptive reference filtering for bidirectional disparity compensation with focus mismatches
In this paper, we consider compensation of focus mismatches for frames that are encoded with inter-view bi-prediction (B-frames) in multiview coding (MVC). We start with an analys...

Design of Q-shift complex wavelets for image processing using frequency domain energy minimization
This paper proposes a new method of designing finitesupport wavelet filters, based on minimization of energy in key parts of the frequency domain. In particular this technique is ...

Image coding with iterated contourlet and wavelet transforms
This paper presents a new coding technique based on a mixed contourlet and wavelet transform. The redundancy of the transform is controlled by using the contourlet at fine scales ...
