Reindexing Techniques. Furht, B., editor In Encyclopedia of Multimedia, pages 768–769. Springer US, 2008. 00000Paper abstract bibtex SynonymsColor palette reorderingDefinitionReindexing techniques refer to imaging algorithms able to reorder the color palette of color-mapped images. Such techniques are able to reduce the overall entropy of the signal attacking the local index redundancy.In color-mapped imaging, higher compression of color-mapped data is often achieved by reducing the local index redundancy. The so-called reindexing techniques aim at finding the optimal reordering without the consideration of all possible color indexing combinations (M! combinations for an image with M colors). The existing reindexing algorithms are devoted to obtain respectively color and index similarity. An extensive survey of popular reindexing techniques can be found in [1].The pixels in the image I with m rows, n columns, and M distinct colors can be represented as I(x,y) = P(I’(x,y)), where P = \S1, S2, ..., SM\ is the set of all the colors in I, and I’ is an m×n matrix of indexes in \1, 2, ..., M\.
