Abstract

The embodiment of the invention discloses a data processing method and device, electronic equipment and a storage medium. The method comprises the steps that a training data set is acquired; the training data set comprises a plurality of images; training the image down-sampling model and the image up-sampling model by using the training data set; wherein in the training process, after a result obtained through processing of the image down-sampling model is subjected to encoding and decoding processing, the image up-sampling model is used for processing. According to the technical scheme, information loss caused by encoding and decoding processes can be reduced, and finally the image down-sampling model and the image up-sampling model which enable the image quality recovery effect to be relatively high can be obtained.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a data processing method, device, electronic equipment, and storage medium. Background technique [0002] In some video playback scenarios such as live broadcast scenarios, due to the impact of user equipment (mainly referring to hardware codec equipment) or network bandwidth, high-resolution videos cannot be used for playback. For example, the common 720P high-definition video (resolution 1280*720) may not be played normally due to the influence of user equipment or the network. In order to solve this problem, the resolution of the image in the video is usually down-sampled. The interpolation method with better quality in the traditional down-sampling method is bicubic linear interpolation (BI). For example, down-sampling 720P HD video twice can To obtain 360P standard definition video (resolution 640*360), the amount of data can be reduced through the above-ment...
