Color editing with simple encoded images

摘要: In an original image in red, green, blue color space (RGB) defined by a large number of colors, variety the is accomplished displaying reduced representative set. The set produced initially treating each separation individually, to reduce levels defining image, manner which retains much information. Subsequently, separations are combined into index look up table (LUT) having between about 27 and 120 RGB triplets. Each triplet one LUT triplets converted luminance/chrominance value. Modifications made luminance/chrominance, back reload for real time variation image. Upon establishing desirable space, values selected, define new position used change colors single step. then again displayed with derived same as described.
