Parameter estimation for an H.264-based distributed video coder
In this paper we present a statistical model used to select coding parameters for a mixed resolution Wyner-Ziv framework implemented using the H.264/AVC standard. This paper exten...

A New Rotation Search for Dependent Rate-Distortion Optimization in Video Coding
We present a novel search algorithm which is suitable for optimizing functions with a high-dimensional discrete-valued parameter vector. The algorithm is designed to find a funct...

Dependency Channel Modeling for a LDPC-Based Wyner-Ziv Video Compression Scheme
Research in distributed video coding for low complexity encoding has shown that without knowledge of the correlation between source and side information (i.e. the behavior of the ...

A Frame-Layer Rate Control Algorithm for H.264 Using Rate-Dependent Mode Selection
Since the H.264 video coding standard becomes quite popular for transmission of diverse multimedia data due to its high coding efficiency, bit allocation and buffer management sche...

Rate-distortion estimation for H.264/AVC coders
In a video coder, the optimal coding mode decision for each coding block could be achieved by exhaustively calculating the Lagrange cost (which includes the coding distortion plus...
