Abstract

The invention relates to the field of information collection and application, in particular to an image compression method and device and a storage medium. The method comprises the following steps: inputting an image sample with a category attribute into a pre-constructed joint learning model; and carrying out joint training on the first initial deep learning model, the second initial deep learning model and the third initial deep learning model of the joint learning model to obtain a compression model comprising an image compression sub-model, an image reconstruction sub-model and a categoryrecognition sub-model. Practical application, and inputting the target image to be compressed into the compression model obtained by training, performing compression processing by utilizing the imagecompression sub-model of the compression model, and obtaining the target compression image corresponding to the target image according to the output of the image compression sub-model. The image compression method and device can realize image compression on the premise of maintaining the original image classification performance.

Description

Technical field [0001] The present invention relates to the field of computer technology, and in particular to an image compression method, device and storage medium. Background technique [0002] Image compression refers to the technique of expressing the original image pixel matrix with fewer bytes. Usually, in order to save storage space when storing images, the images need to be compressed, and the images are restored by decompression when they are actually used or displayed. [0003] At present, tasks such as image classification and image retrieval in computer vision are developing rapidly, but the magnitude of real images is relatively large, and the storage space of images is huge. In the prior art, image compression is used to effectively reduce the amount of data and increase the image transmission rate. However, after the image is compressed, it is difficult to retain all the information of the original image. Therefore, how to compress the image while retaining the or...
