Extending the Depth of Field in Microscopy Through Curvelet-Based Frequency-Adaptive Image Fusion
Limited depth of eld is an important problem in microscopy imaging. 3D objects are often thicker than the depth of eld of the microscope, which means that it is optically impossib...

A New Bidirectionally Motion-Compensated Orthogonal Transform for Video Coding
Motion-compensated lifted wavelets have received much interest for video compression. While they are biorthogonal, they may substantially deviate from orthonormality due to motion...

Hash-Based Motion Modeling in Wyner-Ziv Video Coding
Generally, Distributed video coding (DVC) schemes perform motion estimation at the decoder side, without the current frame being available. In order to generate the side-informati...

Rate Allocation Algorithm for Pixel-Domain Distributed Video Coding Without Feedback Channel
In some video coding applications, it is desirable to reduce the complexity of the video encoder at the expense of a more complex decoder. Distributed Video (DV) Coding is a new p...
