An image data processing method is provided. In the method, a first image data set that includes image data arranged according to a first data format is acquired. The first data format has a first number of dimensions. Interleaving and rearrangement are performed on the image data in the first image data set based on a convolution operation to obtain a second image data set. The image data in the second image data set is arranged according to a second data format. The second data format has a second number of dimensions. The second number of dimensions of the second data format is less than first number of dimensions of the first data format. A target output result is generated based on the convolution operation performed on the second image data set and a second weight data set. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

Interleaving and rearrangement to reduce a number of dimensions of image

A video denoising method includes: performing spatial filtering on pixels of a target image in a video to be processed to obtain a first image, the spatial filtering being used for eliminating dependencies between the pixels of the target image; performing, according to a frame difference between the first image and a first denoised image, temporal filtering on the pixels of the target image in parallel to obtain a second image, the first denoised image being an denoised image that corresponds to a preceding frame of the target image; predicting first gain coefficients corresponding to pixels of the second image in a second denoised image according to second gain coefficients corresponding to the pixels of the target image in the first denoised image; and fusing the first image and the second image according to the first gain coefficients to obtain the second denoised image that corresponds to the target image.
