Model-based sparsity projection pursuit for lattice vector quantization
In this work we present an efficient coding scheme suitable for lossy image compression using a lattice vector quantizer (LVQ) based on statistically independent data projections...

Detecting Digital Image Forgeries by Measuring Inconsistencies of Blocking Artifact
Digital images can be forged easily with today’s widely available image processing software. In this paper, we describe a passive approach to detect digital forgeries by checkin...

Constrained and Unconstrained Simplification of Image Partitions Encoded with the Method of Transition Points
The encoding of image partitions plays a key role in the overall efficiency of the so-called region-based image coding techniques. Recently, a method based on the novel concept o...

Selective And Scalable Encryption Of Enhancement Layers For Dyadic Scalable H.264/avc By Scrambling Of Scan Patterns
This paper presents a new selective and scalable encryption (SSE) method for intra dyadic scalable coding framework based on wavelet/subband (DWTSB) for H.264/AVC. It has been ach...
