We lay out a theoretical framework to evaluate watermarking techniques for intellectual property protection (IPP). Based on this framework, we analyze two watermarking techniques ...
Diffusion curves are a powerful vector graphic representation that stores an image as a set of 2D Bezier curves with colors defined on either side. These colors are diffused over...
A very undesirable behavior of any heuristic algorithm is to be stuck in some specific parts of the search space, in particular in the basins of attraction of the local optima. Wh...

Given a simple graph G, a harmonious coloring of G is a proper vertex coloring such that each pair of colors appears together on at most one edge. The harmonious chromatic number i...
To demonstrate the performance of color image processing algorithms, it is desirable to be able to accurately display color images in archival publications. Our previous work [1],...
