A PAINT SYSTEM OF MONOCHROMATIC MOVING IMAGES

A method for painting a sequence of monochromatic images is proposed. In this method, a color model, whose base components are hue, saturati on and intensity, is used to keep the lightness of images unchanged be fore and after painting. Two successive frames in the monochromatic im age sequence and a colored image of the first frame which is interacti vely painted. are analyzed in order to paint the next monochromatic fr ame. The painting process is composed of two phases. that is. an autom atic coloring phase and an interactive retouching phase. In the automa tic coloring phase, hierarchical image segmentation and region matchin g procedures are performed, and the two attributes of hue and saturati on are mapped from the painted image of the first frame to the next im age. In the retouching phase, using an interactive paint system based on the color model, users can modify the chromatic components of pixel s whose colors were not mapped correctly. Several experiments show tha t our method is very effective in reducing tedious painting.
