Modified MPEG-2 video coders with efficient multi-layer scalability
The paper describes a multi-layer video coder based on spatiotemporal scalability and data partitioning. The coder consists of two parts: a low-resolution coder and full-resolutio...

Constant pace skimming and temporal sub-sampling of video using motion activity
We describe a "constant pace" framework for video summarization via fast playback or temporal subsampling. The pace of the summary serves as a parameter that enables pro...

An evolving localised learning model for on-line image colour quantisation
Although widely studied for many years, colour quantisation remains a practical problem in image processing. Unlike previous works where the image can only be quantised after the ...

FM halftoning via block error diffusion
Error diffusion halftoning is a popular method of producing frequency modulated (FM)halftones. In FM halftoning the dot size and shape is fixed (equal to one pixel) and the dot fr...

Use of a probabilistic shape model for non-linear registration of 3D scattered data
In this paper we address the problem of registering 3D scattered data by the mean of a statistical shape model. This model is built from a training set on which a principal compon...
