Embodiment Construction

[0069] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0070] Due to the continuous development of software and hardware, people hope to obtain higher-quality multimedia materials, such as classic movies, high-definition remakes of games, and high-resolution low-resolution videos. These requirements have not yet been fully resolved. The first difficulty is that the types and degrees of low-quality multimedia materials in reality are difficult to measure with definite mathematical formulas, and can only be roughly distinguished based on assumptions; the second difficulty is the human eye's perception of multimedia materials. High-quality cognition has certain uncertainties, and there will be many differences in the identification of high-quality.

[0071] The low quality of the image may be caused by various factors, such as the impact of noise, the impact o...

Abstract

The embodiment of the invention provides an image reconstruction method, device and equipment, wherein the method comprises the following steps of obtaining an image to be processed, wherein the imageto be processed is a low-quality image whose image quality does not meet a preset condition; inputting the image to be processed into a pre-trained convolution neural network model, and obtaining a reconstructed image corresponding to the image to be processed, wherein the reconstructed image is a high-quality image whose image quality satisfies the preset conditions, the trained convolution neural network model is obtained by training a plurality of first training samples and a preset second training sample after each first training sample is processed respectively, the first training sampleis a high-quality image whose image quality satisfies a preset condition, and the second training sample is a low-quality image whose image quality does not satisfy the preset condition. Thus, the complexity of the calculation process can be reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image reconstruction method, device and equipment. Background technique [0002] Due to the limitations of previous software and hardware, the quality of multimedia materials will be adversely affected during the production, transmission and storage of pictures, videos and other multimedia materials. Typical examples include shooting distortion caused by obsolete photographic equipment, compression distortion caused by video transcoding and compression, etc. Nowadays, major Internet companies cite each other's multimedia data, resulting in repeated compression of pictures and videos, resulting in low-quality multimedia data. However, due to the continuous development of software and hardware, people hope to obtain higher-quality multimedia materials, such as classic movies, high-definition remakes of games, and high-resolution low-resolution videos.
