A chaos-based video watermarking algorithm

The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...

A Histogram Based Watermarking Algorithm Robust to Geometric Distortions

Most of the histogram-based watermarking methods focused on the geometric invariance feature more while paying less attention to the robustness to some common image processing attacks like JPEG compression. In this paper, we propose a new histogram modification scheme considering the visual quality of the watermarked image while combining block dividing and histogram statistics for the first ti...

A histogram-based algorithm for semiautomated three-dimensional craniofacial modeling.

RATIONALE AND OBJECTIVES I conducted a study designed to facilitate thresholding and reduce volume averaging in three-dimensional (3D) computed tomography (CT) craniofacial modeling. METHODS Three-dimensional CT reconstructions of orbits from two cadavers and seven clinical cases were generated from paired axial and coronal data. A histogram-based algorithm that was based on preliminary phant...

A partition-based algorithm for clustering large-scale software systems

Clustering techniques are used to extract the structure of software for understanding, maintaining, and refactoring. In the literature, most of the proposed approaches for software clustering are divided into hierarchical algorithms and search-based techniques. In the former, clustering is a process of merging (splitting) similar (non-similar) clusters. These techniques suffered from the drawba...
