Abstract
The present disclosure provides an image processing method and apparatus, a device, and a medium, and relates to the field of image and video processing technologies. An implementation solution includes: performing frequency domain transform on a target image and obtaining a frequency coefficient matrix of the target image, the frequency coefficient matrix including at least one non-zero frequency coefficient; determining a non-zero block in the frequency coefficient matrix based on a position of the at least one non-zero frequency coefficient; determining a corresponding transform submatrix and a corresponding transposed submatrix of the non-zero block; and determining an inverse transform result of the frequency coefficient matrix based on the transform submatrix, the non-zero block, and the transposed submatrix.
