R-D Optimized Frame-Layer Bit Allocation for H.264
— The frame-layer bit allocation problem for H.264 is studied in this work. We first impose a GOP (Group of Pictures) structure on the underlying H.264 video, and then develop a...

A global optimization framework for meeting summarization
We introduce a model for extractive meeting summarization based on the hypothesis that utterances convey bits of information, or concepts. Using keyphrases as concepts weighted by...

Wireless Video Transmission: A Single Layer Distortion Optimal Approach
In this paper, we introduce an analytical expression for the expected distortion of a single layer encoded video bit-stream. Based on the expected distortion model, we propose a d...

Bit Allocation in Sub-linear Time and the Multiple-Choice Knapsack Problem
We show that the problem of optimal bit allocation among a set of independent discrete quantizers given a budget constraint is equivalent to the multiple choice knapsack problem (...

Semi-Fuzzy Rate Controller for Variable Bit Rate Video
A novel semi-fuzzy (SF) rate control algorithm (RCA) for variable bit rate (VBR) video applications is proposed. The proposed RCA is optimized to provide high quality compressed vi...
