New negative Latin square type partial difference sets in nonelementary abelian 2-groups and 3-groups
A partial difference set having parameters (n2, r(n - 1), n + r2 - 3r, r2 - r) is called a Latin square type partial difference set, while a partial difference set having paramete...

Improved versions of Tardos' fingerprinting scheme
We study the Tardos' probabilistic fingerprinting scheme and show that its codeword length may be shortened by a factor of approximately 4. We achieve this by retracing Tardo...

Object-Based Regions of Interest for Image Compression
A fully automated architecture for object-based region of interest (ROI) detection is proposed. ROI's are defined as regions containing user defined objects of interest, and ...

A Novel Partial Prediction Algorithm for Fast 4x4 Intra Prediction Mode Decision in H.264/AVC
This paper proposes a partial prediction approach for fast mode decision in H.264/AVC 4x4 intra-prediction, exploiting the inherent symmetry existing in the spatial prediction mod...

Simultaneous Encryption/Compression of Images Using Alpha Rooting
Significant work has been done in the areas of image encryption and compression as two independent problems, yet the two areas are strongly interleaved and should be considered si...
