Apparatus and method for enhancing photorealism of computer graphic image

摘要

An apparatus and method for enhancing photorealism of a computer graphic (CG) image. Since color distribution maps of the CG image and a realistic image are extractable, a color distribution map of an input CG image may be adjusted, thereby enhancing photorealism of the CG image.

1. A method of enhancing a computer graphic (CG) image, the method comprising:
receiving, by a processor, an input of the CG image; obtaining a color distribution map of the input CG image; and adjusting the color distribution map of the input CG image by rotating a reference axis related to an average vector according to an average hue and the average vector of the input CG image such that a point including the average hue and the average vector is within a threshold range of a color distribution map of pre-stored realistic image group in lieu of a threshold range of a color distribution map of a pre-stored CG image group, wherein the color distribution map of the input CG image is adjusted to be positioned within the threshold range close to the color distribution map of the realistic image group.
