  • Image edge enhancement processing method and application thereof
    Patent number: 12430770
    Abstract: This application discloses an image edge enhancement processing method and application thereof. This application relates to the technical field of digital image processing. The method includes: receiving an input image separated into a luminance signal and a chrominance signal; obtaining a first edge value by processing the input luminance image with a first set of parameters applicable to non-facial skin tone points, and obtaining a second edge value by processing the input luminance image with a second set of parameters applicable to facial skin tone points; obtaining a skin tone weight value for each skin tone point, and obtaining the facial skin tone weight value for each point according to the face region information of the input image; blending the first edge value with the second edge value according to the facial skin tone weight value, and combining the blended edge value with the input luminance value for edge enhancement.
    Type: Grant
