Abstract: The choice of a relevant colour space is a crucial step when dealing with image processing tasks (segmentation, graphic recognition…). From this fact, we address in a generic way the following question: What is the best representation space for a computational task on a given image? In this article, a colour space selection system is proposed. From a RGB image, each pixel is projected into a vector composed of 25 colour primaries. This vector is then reduced to a Hybrid Colour Space made up of the three most significant colour primaries. Hence, the paradigm is based on two principles, feature selection methods and the assessment of a representation model. The quality of a colour space is evaluated according to its capability to make colour homogenous and consequently to increase the data separability. Our framework brings an answer about the choice of a meaningful representation space dedicated to image processing applications which rely on colour information. Standard colour spaces a re not well designed to process specific images (ie. Medical images, image of documents) so a real need has come up for a dedicated colour model. (More)
