Original Abstract

The contribution deals with the Matlab application used for television colorimetry and color spaces analysis. The mathematical description of known color spaces (RGB, XYZ, YUV, YIQ, YCbCr, HSV, CMY, CMYK) is introduced including their reciprocal transformation. The application allows selection of input color image, direct and backward transformation into the selected space including MKO, CIE and RG diagram picture analysis. The projection of color image in 2D and 3D color vectors is then possible. The additional functions are evaluation of histogram, gamma correction, picture line selection for the analysis etc. The Color_Spaces application outputs are introduced in examples applied on various test pictures.
