An image data processing method and device are disclosed, which are applied to a first electronic device. The method includes: extracting a first intermediate image block in a first image, where the first image includes M rows and N columns of pixels, and the first An intermediate image block includes I rows and J columns of pixels, M≥I, N≥J; calculate the sum of pixel values of each row of pixels in the first intermediate image block, and store I first values; use the stored I first values, and sequentially calculate the average pixel value of each first image block in the (I-m+1) first image blocks in the first intermediate image block, wherein the first image block includes m rows Pixels in column J, I>m. By extracting a first intermediate image block in the first image that is larger than the image block used for correlation calculation, performing data analysis and calculation on the first intermediate image block and saving the intermediate calculation result, and using the intermediate calculation result for the first intermediate image block In the correlation calculation of a plurality of first image blocks included in , multiplexing of computing resources is achieved.
Description
technical field [0001] The present invention relates to the technical field of image processing, and more particularly relates to an image data processing method and device. Background technique [0002] In image processing such as image encoding, image decoding, and moving image analysis, it is generally necessary to calculate the correlation between image blocks in two images. When calculating the correlation between image blocks in two images, generally, a fixed-size image block is selected as the calculation object. Such as figure 1 As shown, the first image block in the first image and the second image block in the second image are shown, figure 1 Both the first image block and the second image block in are image blocks of 9×9 pixels. [0003] Taking the calculation of the correlation between the first image block in the first image and the second image block in the second image as an example, the correlation between the first image block and the second image block c...
