ABSTRACT: CWe describe a method and software to analyze the content of images and build their colorimetric profile as perceived by the user.
First, images are being processed relying on a standard or initial set of parameters using the fuzzy set theory and the HLS color space (Hue, Lightness, Saturation). The number of these parameters is considerable and they present the different colors and properties of colors in combinations i.e. red pale, blue dark. Access is done pixel by pixel and at the end of this phase each image will have a detailed initial colorimetric profile.
Second, we present a method that will recalculate the amount of colors in the image based on another set of parameters, so the colorimetric profile of the image is being modified accordingly. Avoiding the repetition of the process at the pixel level is the main target of this phase, because reprocessing each image is time consuming and turned to be not feasible.
Finally we present the software used to process images and recalculate their colorimetric profiles with some examples.
