Abstract
In this paper we introduce a competitive neural model called Magnitude Sensitive Competitive Learning (MSCL) for Color-Quantization. The aim is to obtain a codification of the color palette taking into account some specific regions of interest in the image, such as salient area, center of the image, etc. MSCL algorithm allows distributing color vector prototypes in the desired data regions according to a magnitude function. This magnitude function can allocate the codewords (colors of the palette) not only in relation to their frequency but also in response to any other data-dependent magnitude tailored to the specific goal. As we show in five different examples in this paper, MSCL is able to surpass the performance of other standard Color Quantization algorithms.
