Abstract

The invention provides an image processing method, device, equipment and system. The method comprises the following steps: acquiring decoded image information; inputting the decoded image information to a first processing network, and processing the decoded image information by the first processing network to obtain a distorted image corresponding to the decoded image information; and inputting a target image corresponding to the distorted image to a second processing network, so that the second processing network performs artificial intelligence processing for realizing intelligent analysis according to the target image, wherein the first processing network is obtained by training according to the features of the sample image before coding and the features of the distorted sample image corresponding to the decoded sample image. Through the technical scheme of the invention, the compression loss in the image can be avoided or reduced.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image processing method, device, equipment and system thereof. Background technique [0002] During image processing, processing such as filtering, data rounding, and quantization may cause intensity shifts in pixel values, resulting in visual disturbances or artifacts. To avoid or mitigate the above problems, images can be post-processed using de-distortion filters to restore pixel intensity shifts and mitigate visual loss. Traditional de-aliasing filters usually generalize the characteristics of distorted images artificially, use the features to construct de-distortion filters, artificially design the structure of the distortion filter, and configure the coefficients of the distortion filter based on experiments and experience. [0003] In recent years, deep learning networks have developed rapidly. Driven by training data, deep neural networks can ad...
