Abstract

The invention discloses an image processing method and device. The method comprises steps of receiving data sent by a sending end, and determining a wavelet coefficient according to the received data, wherein the data sent by the sending end comprises a wavelet coefficient obtained through wavelet decomposition performed on an original image; according to the wavelet coefficient, generating a low-resolution image; and according to a neural network, carrying out ultra-resolution reconstruction on the low-resolution image so as to obtain a high-resolution image. According to the invention, a technical problem of a failure to meet quite high compression efficiency and quite high image restoration quality in an image compression method in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] During image transmission, the limitation of bandwidth makes it impossible to take into account the size of the image and the transmission time of the image, and it is usually necessary to compress the image. Traditional image compression methods are limited to removing redundancy from image data from a mathematical point of view. The algorithm design framework is basically fixed, and it is difficult to greatly improve the compression efficiency. The system has no learning function, and the quality of the generated image is fixed. When the bandwidth limit is severe , has a huge impact on image quality. In the prior art, the wavelet transform may be used to compress the image, and super-resolution reconstruction is performed on the compressed low-resolution image after image compression. Wavelet transfor...
