A Rate-Distortion Approach to Wavelet-Based Encoding of Predictive Error Frames
In this paper, we develop a framework for efficiently encoding predictive error frames (PEF) as part of a rate scalable, wavelet-based video compression algorithm. We investigate ...

Algebraic Structures for Bipolar Constraint-Based Reasoning
The representation of both scales of cost and scales of benefit is very natural in a decision-making problem: scales of evaluation of decisions are often bipolar. The aim of this ...

Segmentation Using Saturation Thresholding and Its Application in Content-Based Retrieval of Images
We analyze some of the visual properties of the HSV (Hue, Saturation and Value) color space and develop an image segmentation technique using the results of our analysis. In our me...

A Message Authentication Code Based on Unimodular Matrix Groups
We present a new construction based on modular groups. A novel element of our construction is to embed each input into a sequence of matrices with determinant ±1, the product of w...

Detection of Illegal Behaviors Based on Unfoldings
We show how the branching process approach can be used for the detection of illegal behaviors. Our study is based on the specification of properties in terms of testers that cover...
