Colorization method and apparatus

摘要

A method for colorization of images is presented. The method comprises the following steps: Displaying an image (102); applying multiple color markings (at least two colors are different) to the displayed image (104); automatically coloring the image by applying a constrained optimization to a cost function that is responsive to the marked colors and the intensity differences of the neighborhoods of some of all of the pixels (106); the resultant image is subsequently stored (110), displayed (108), or transferred (112).

主权项

1. An apparatus for colorization of images, comprising:
an image display; a user input adapted to mark an original image displayed on the display with multiple color markings, at least some of which are in different colors, the original image without the color markings; and a controller, which receives the user generated markings and colors at least one non-marked region of the image responsive to the marked colors and the intensity of the original image, the at least one non-marked region of the image between two or more spaced apart markings of different colors is colored by mixing the different colors, the extent of said mixing dependent on differences between the intensity of a pixel located within the at least one non-marked region of the original image, and a function of intensity of neighboring pixels of the original image, the neighboring pixels located within a predefined computational window around the pixel.
