A nonlinear loop filter for quantization noise removal in hybrid video compression
We propose a high-performance, nonlinear, loop filter that reduces quantization noise over video frames composed of locally uniform regions (smooth, high frequency, texture, etc.)...

Measuring the added high frequency energy in compressed video
A major focus of video quality assessment research has been to quantify the amount of blocking, blurring, and ringing impairments. However, little attention has been paid to anoth...

Data hiding using trellis coded quantization
Information theoretic tools lead to the design and analysis of new blind data hiding methods. A novel quantizationbased blind method, which uses trellis coded quantization, is pro...

Analysis of the efficiency of snr-scalable strategies for motion compensated video coders
In this paper, an analysis of the efficiency of three signal-to-noise ratio (SNR) scalable strategies for motion compensated video coders and their non-scalable counterpart is pre...

Shape adaptation for light field compression
We propose a method of using shape adaptation for compression of light fields of 3-D objects. Shape adaptation is incorporated into two light field coders, both applying disparity...
