Problems solved by technology

[0003] At present, the super-resolution algorithm is often used for image enlargement. Since the super-resolution algorithm is different from the detection, classification and segmentation algorithms, it is enlarged on the basis of the original input image, which requires a large number of floating-point calculations, resulting in a larger processing model. It may also cause image distortion

Abstract

The invention discloses an image processing method and device, a terminal and a storage medium. The image processing method comprises the steps of obtaining to-be-processed low-resolution image information; acquiring a first feature map according to the to-be-processed low-resolution image information; inputting the first feature map into an image restoration model for processing, wherein the image restoration model is a model obtained by training based on a cascaded residual convolutional neural network; and acquiring the processed restored image information, thus the feature map and the cascaded residual convolutional neural network can be applied to perform image processing, the model size during image processing is reduced, and the image processing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, terminal and storage medium. Background technique [0002] With the development of science and technology, more and more people use video and pictures to commemorate precious moments in life. However, in order to transmit efficiently and save space and time, the video picture files need to be compressed during storage and transmission. The compression will selectively retain the image information, and after the image is enlarged again, the clarity and fidelity will be reduced due to the lack of image information. Therefore, it is necessary to restore and enlarge the compressed image. [0003] At present, the super-resolution algorithm is often used for image enlargement. Since the super-resolution algorithm is different from the detection, classification and segmentation algorithms, it is enlarged on the basis of the original...
