New Results on Efficient Optimal Multilevel Image Thresholding
Image thresholding is one of the most common image processing operations, since almost all image processing schemes need some sort of separation of the pixels into different class...

Digital Image Forensics for Identifying Computer Generated and Digital Camera Images
We describe a digital image forensics technique to distinguish images captured by a digital camera from computer generated images. Our approach is based on the fact that image acq...

Improved Unsymmetric-Cross Multi-Hexagon-Grid Search Algorithm for Fast Block Motion Estimation
We develop a set of new motion estimation (ME) algorithms based mainly on Unsymmetric-Cross Multi-Hexagon-Grid Search (UMH). The original algorithms are improved by applying the S...

Content Adaptive Wyner-ZIV Video Coding Driven by Motion Activity
In distributed video coding (DVC), the video statistics are exploited, partially or totally at the decoder. A particular case of DVC, WynerZiv video coding deals with lossy source...

Studying Temporal Correlation Noise Modeling for Pixel Based Wyner-Ziv Video Coding
Wyner-Ziv (WZ) video coding ? a particular case of distributed video coding (DVC) ? is a new video coding paradigm based on two major Information Theory results: the Slepian-Wolf ...
