Abstract

The invention relates to an image data processing method, a device, computer equipment and a storage medium. The method is applied to a graphics processor, and comprises the following steps: a computer device determines the number of thread blocks according to the number of original images and the number of original pixels, determines a global index corresponding to each thread block, and determines the number of thread blocks according to the global index of each thread block, the number of pixels of each original image and the number of original images; calculating indexes of to-be-processed image pixels corresponding to the thread blocks; and calling each thread block, and performing pixel shifting operation according to the index of the to-be-processed image pixel corresponding to each thread block, wherein the to-be-processed image is a preset region in the original image. The method is applied to the GPU, and based on the operating environment of the GPU and the image data processing mode provided by the scheme, the computer equipment can call each thread block to synchronize a plurality of images to be processed for image processing based on the indexes of the pixels of the images to be processed, so that the image processing efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image data processing method, device, computer equipment and storage medium. Background technique [0002] The Fast Fourier Transform (FFT) algorithm is a mathematical tool that is often used in image signal processing, and it is widely used in the changes in the spatial domain and time domain of image processing. FFT shifting is a necessary sub-process of any FFT operation and is used to set the zero frequency of the resulting spectrum at the image origin. [0003] In the prior art, the FFT shift operation is generally performed based on the central processing unit CPU, specifically performing the FFT shift operation on a two-dimensional image once, and then performing subsequent operations on the image processed by the FFT shift operation. [0004] However, in the prior art, the image processing efficiency is low in the manner of performing a shift operat...
