Abstract: Implementations of the present disclosure provide a solution for image/video processing. In this solution, an intermediate image can be obtained from an LR image. Then, a smooth value associated with an image block in the intermediate image could be determined based on a gradient of a target pixel in the image block. Further, an HR image can be generated from the intermediate image based on the smooth value. In this way, the filtering process can be performed based on a smooth value of an image block, thereby improving the efficiency of image/video processing and lowering down the computational and memory costs.
