Abstract

The invention provides an image zooming processing method and device, equipment, a computer readable storage medium and a computer program product. The method comprises the following steps: updating a first grayscale image of a to-be-processed image based on an edge detection operator to obtain a second grayscale image; determining an energy value of each pixel point in the second grayscale image; according to the energy value of each pixel point in the second grayscale image, determining an energy ray matched with the scaling processing direction in the to-be-processed image, wherein the sum of energy of a plurality of pixel points included in the energy ray meets an energy condition; and performing fusion processing on a plurality of pixel points associated with the energy rays in the to-be-processed image to obtain a scaled image. Through the invention, the image can be adaptively and accurately zoomed, and the method and the device can be applied to scenes such as cloud technology, artificial intelligence, intelligent traffic and auxiliary 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 [...
