4.4 Matrix-valued Images co-domain in Rn x m. For example Diffusion Tensor Magnetic Response Imaging. 4.5 Image Sequence this increases the dimensionality of the domain from m to m+1 summary: Digital images have a discrete domain (sampling) and a discrete co-domain (quantisation) generalisation...
Image quality Human mental searchMetaheuristicColour quantisation is a common image processing technique to reduce the number of distinct colours in an image which are then rep- resented by a colour palette. The selection of appropriate entries in this palette is a challenging issue while the ...
Colour quantisation is very often used as an auxiliary operation in colour image processing, e.g. this operation can reduce the complexity of image segmentation process. In this chapter the results of segmentation preceded by a colour quantisation have been compared with segmentation without such ...
