Title:
METHOD FOR PROCESSING IMAGE EDGE, ELECTRONIC DEVICE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/200657
Kind Code:
A1
Abstract:
Disclosed is a method for processing an image edge, comprising: extracting a luminance component from an inputted image; performing, according to the luminance component, calculation to obtain an edge probability (mp) of each pixel in the image; performing, according to the edge probability (mp), calculation to obtain an enhancement coefficient λ for each pixel; performing, according to the luminance component, noise detection to determine whether each pixel in the image is a noise point; if the pixel is not a noise point, performing logarithm-based processing on the pixel to obtain w; enhancing an edge of the image according to λ, w and the luminance component; and after compositing luminance components according to luminance component data obtained after the enhancement, outputting the enhanced image. Also disclosed in an embodiment of the present invention are an electronic device, and a computer readable storage medium. The invention can enhance the profile of an image to sharpen the image, thereby improving image quality.
