A Paint System of Monochromatic Moving Images

概要

A method for painting a sequence of monochromatic images is proposed. In this method, a color model, whose base components are hue, saturation and intensity, is used to keep the lightness of images unchanged before and after painting. Two successive frames in the monochromatic image sequence and a colored image of the first frame which is interactively painted, are analyzed in order to paint the next monochromatic frame. The painting process is composed of two phases, that is, an automatic coloring phase and an interactive retouching phase. In the automatic coloring phase, hierarchical image segmentation and region matching procedures are performed, and the two attributes of hue and saturation are mapped from the painted image of the first frame to the next image. In the retouching phase, using an interactive paint system based on the color model, users can modify the chromatic components of pixels whose colors were not mapped correctly. Several experiments show that our method is very effective in reducing tedious painting.
