Theoretical Model of the Coding Error in MCWT Video Coders
In motion-compensated wavelet based video coders (MCWT), it is known that a precise motion estimation is necessary to minimize the wavelet coefficients energy. However, a motion v...

Scan order and quantization for 3D-DCT coding
Two types of coders dominate the field of video compression research today: well-established hybrid coders, that are in the core of all MPEG and H.26X standards, and emerging thr...

Sparse Coding via Thresholding and Local Competition in Neural Circuits
While evidence indicates that neural systems may be employing sparse approximations to represent sensed stimuli, the mechanisms underlying this ability are not understood. We desc...

Coding structure optimization for interactive multiview streaming in virtual world observation
—While most multiview coding techniques focus on compressing all frames in a multiview video sequence in a ratedistortion optimal manner, in this paper we address the problem of ...

Adaptive Filtering for Video Coding with Focus Change
We propose an adaptive ltering approach for coding video that exhibits localized camera focus changes, e.g., such that different portions of a video frame can undergo different bl...
