Group Testing for Video Compression
Hong and Ladner [6] used context-based group testing to implement bitplane coding for image compression. We extend this technique to video coding, by replacing the quantization an...

Length-Limited Variable-to-Variable Length Codes For High-Performance Entropy Coding
Arithmetic coding achieves a superior coding rate when encoding a binary source, but its lack of speed makes it an inferior choice when true high? performance encoding is needed. ...

Coding for Fast Access to Image Regions Defined by Pixel Range
Many technical imaging applications, like coding "images" of digital elevation maps, require extracting regions of compressed images in which the pixel values are within...

Universal Coding of Function Spaces as a Model for Signal Compression
We address the problem of signal compression, basing on the mathematical model, in which a set of all possible signals is considered as a function space with a metric . The main a...

On the Complexity of Rate-Distortion Optimal Streaming of Packetized Media
We consider the problem of rate-distortion optimal streaming of packetized media with sender-driven transmission over a single-QoS network using feedback and retransmissions. For ...

Global MINMAX Interframe Bit Allocation for Embedded Video Coding
We present three new bit allocation techniques, the MultiStage algorithm, the Ratio algorithm, and the Pseudo I-frame method. The MultiStage and Ratio algorithms are global interf...

Discrete Universal Filtering Through Incremental Parsing
In the discrete filtering problem, a data sequence over a finite alphabet is assumed to be corrupted by a discrete memoryless channel. The goal is to reconstruct the clean sequenc...
