Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0031]Assuming that adjacent pixels with similar brightness values in space have similar color values, the present invention proposes a simple colorization method based on this assumption, which requires neither accurate image segmentation nor accurate region tracking. We then transform this colorization problem into an optimization problem that can be efficiently solved by existing algorithms. In order to get better results, we use the L1 and L2 mixed norm to so...
