Problems solved by technology
[0003] In the existing technology, the super-resolution method is mainly used to improve the resolution of the image. However, with the development of deep learning technology, the effect of traditional super-resolution methods (such as double-three interpolation, spline interpolation, etc.) has lagged behind greatly. , the reason is that the super-resolution image reconstruction method based on a single image has less available information on the target, which makes it very difficult to effectively improve the super-resolution effect, and lacks an effective description of edges and textures, thus make the resulting image blurry

The embodiment of the invention discloses an image processing method and device used for optimizing the effect of converting a low-pixel image into a high-pixel image. The method comprises the steps that target images are acquired, and key regions in the target images are determined; deep characteristics in the key regions are extracted according to a pre-generated multi-scale image model, whereinthe multi-scale image model comprises deep characteristic information of all the target images in the key regions under at least one size; and the target images and the deep characteristics in the key regions are processed to obtain high-resolution target images corresponding to the target images. Through the technical scheme, key characteristics in the target images can be sufficiently mined, the finally obtained high-resolution target images can fully depict edges and texture of the key regions, and the effect of increasing the resolution of the target images is optimized.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] With the development of technology, how to use computer image processing technology and computer vision technology to generate a high-pixel face from a low-pixel face has become another important development direction in the fields of security and detection. As the main basis for security and detection, face recognition has received more and more attention in recent years. However, due to the limited number of pixels that can be covered by the actual camera, under the condition of ensuring the breadth, it will inevitably lose the coverage of the target pixels, and the low-pixel image will inevitably lead to a decrease in accuracy when performing face recognition. Therefore, how to convert a low-pixel face image into a high-pixel face becomes more and more important. [0003] In the existing te...
