Document Type and Number:
WIPO Patent Application WO/2021/254381
Kind Code:
A1
Abstract:
An image processing method, comprising: according to a position coordinate, in a target image, of any interpolation pixel point to be processed of the target image, determining a position coordinate of the interpolation pixel point in an original image; calculating a two-dimensional image entropy of the interpolation pixel point in an n×n neighborhood of the original image; when the two-dimensional image entropy is greater than or equal to a preset entropy threshold, calculating a pixel value of the interpolation pixel point by a first interpolation algorithm on the basis of all original pixel points within the n×n neighborhood; when the two-dimensional image entropy is less than the preset entropy threshold, calculating gradient values of at least two edge directions within the n×n neighborhood, and determining whether there is a strong-edge direction in the at least two edge directions; if so, calculating the pixel value of the interpolation pixel point by the first interpolation algorithm on the basis of the plurality of original pixel points in the strong-edge direction within the n×n neighborhood; and if not, calculating the pixel value of the interpolation pixel point by a second interpolation algorithm on the basis of all the original pixel points within the n×n neighborhood.
