The present application provides an image scaling processing method, device, device, and computer-readable storage medium; the method includes: updating the first grayscale image of the image to be processed based on an edge detection operator to obtain a second grayscale image; determining The energy value of each pixel in the second grayscale image; according to the energy value of each pixel in the second grayscale image, determine the energy line matching the scaling processing direction in the image to be processed, wherein the energy line includes The energy summation of multiple pixel points satisfies the energy condition; multiple pixel points associated with the energy lines in the image to be processed are fused to obtain a zoomed image. Through this application, images can be adaptively and accurately scaled, and the embodiments of this application can be applied to scenarios such as cloud technology, artificial intelligence, intelligent transportation, and assisted driving.
Description
technical field [0001] The present application relates to image processing technology, and in particular to an image scaling processing method, device, equipment, computer-readable storage medium, and computer program product. Background technique [0002] Image scaling refers to reducing the image to be processed by cropping the image to be processed, or enlarging the image to be processed by a difference method. For example, the size of the image to be processed is M*N, and the size of the reduced image is required to be m*n, then the image to be processed needs to be divided into disjoint small blocks of size (M*N) / (m*n) , and calculate the average value of each small block, and use each average value as the corresponding pixel value of the reduced image to realize the reduced image. [0003] However, the image scaling solution in the related art is likely to cause problems such as image deformation, resulting in inaccurate image scaling. Contents of the invention [...
