A novel video encryption technique based on secret sharing
The rapid growth of the Internet and digitized content made video distribution simpler. Hence the need for video data protection is on the rise. In this paper, we propose a secure...

Design and performance of a novel low-density parity-check code for distributed video coding
Low-density parity-check (LDPC) codes are nowadays one of the hottest topics in coding theory, notably due to their advantages in terms of bit error rate performance and low compl...

An evaluation of several mesh-generation methods using a simple mesh-based image coder
A simple image coder based on triangle meshes is proposed, and several mesh-generation methods are presented, some previously proposed and some new. Then, our coder is used to eva...

On optimal royalty costs for video compression
Modern video compression includes a mature set of codecs, tools, and techniques that correspond to a variety of coding efficiencies and royalty costs in video delivery. In early ...

Blind deconvolution of video sequences
We present a new blind deconvolution method for video sequence. It is derived following an inverse problem approach in a Bayesian framework. This method exploits the temporal cont...

Perceptual soft thresholding using the structural similarity index
In this paper, we present a novel algorithm for wavelet domain image denoising using the soft thresholding function. The thresholds are designed to be locally optimal with respect...

Compressed sensing for multi-view tracking and 3-D voxel reconstruction
Compressed sensing(CS) suggests that a signal, sparse in some basis, can be recovered from a small number of random projections. In this paper, we apply the CS theory on sparse ba...

Spatio-temporal video interpolation and denoising using motion-assisted steering kernel (MASK) regression
In this paper, we extend a (2-D) data-adaptive steering kernel regression framework for image processing to a (3-D) spatio-temporal framework for processing video. In particular, ...

Exploiting local auto-correlation function for fast video to reference image alignment
Digital images of natural scenes are usually characterized by strong spatial correlation between adjacent pixels which has been successfully exploited in the coding of still and m...
