A comparison of lossleess compression results is given for RGB, YCRCB and reversible JPEG 2000 color space. The paper describes the general conditions that rounding errors of a co...
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...
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...
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 ...
This paper presents an efficient method for the estimation and recovering from nonlinear or local geometrical distortions, such as the random bending attack and restricted project...
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...
Wc optimizc thc noisc shaping bchavior of color crror diffusion by designing an optirnizcd crror filtcr bascd on a proposed noisc shaping modcl for color crror diffusion and a gcn...
This paper presents an approach to ameliorate the reliability of the correspondence points relating two consecutive images of a sequence. The images are especially difficult to ha...
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...
