Abstract
Systems and methods of re-coloring digital images are disclosed. A system including a processor and a memory can execute stored instructions to obtain luminance information of a first image, e.g., an original grayscale image, and obtain color information of a second image, e.g., a colorized image of the original grayscale image. Multiple segmented image regions can be determined based on the luminance information of the first image. A color seed for each segmented image region can be determined based on the color information of the second image. A third image, e.g., a re-colored image, can be determined based on diffusing the color seeds of the segmented image regions.
