Constant quality rate-control for video encoding based on activity segmentation
An enhanced, off-line, segment-based rate control approach is proposed for controlling the distortion variation across successive segments of a video sequence when encoding with s...

Video coding using a deformation compensation algorithm based on adaptive matching pursuit image decompositions
Today's video codecs employ motion compensated prediction in combination with block matching techniques. These techniques, although achieving some level of adaptivity in thei...

Prescient R-D optimized packet dependency management for low-latency video streaming
We present an improved, prescient, scheme to deliver pre-encoded video streams at very low latency. We dynamically manage the prediction dependency for a group of packets using a ...

An integrated multiple-substream unequal error protection and error concealment algorithm for Internet video applications
This paper presents a coordinated multiple-substream unequal error protection and error concealment algorithm for SPIHT-coded bitstreams transmitted over lossy channels. In the pr...

Blocking Artefact Free Video Coding Based on a Bilinear Forward Image Warping Model
In this paper a new very low bit rate video coding scheme is presented. It is based on a forward motion estimation technique using an image warping model, thus delivering the basi...
