Abstract

The invention relates to an image processing method and device and a computer readable storage medium, and relates to the technical field of image processing. The image processing method comprises thefollowing steps: extracting a plurality of thumbnails from a video file; grouping the plurality of thumbnails according to the resolution of the thumbnails and the maximum resolution supported by thepicture format of the thumbnails; and splicing the thumbnails in each group into a combined graph, so as to process the combined graph of each group in batches. The method and the device can improvethe image processing efficiency and improve the processing performance of the system.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image processing method, device and computer-readable storage medium. Background technique [0002] With the development of cloud computing technology, it is necessary to edit and process a large number of videos, audio and video uploaded by users to the cloud through a browser (for example, delete some clips, add special effects, merge video clips, etc.). [0003] A key operation in the video editing process is that the user can see the thumbnails of each second of each video clip in real time, so as to locate the video content and observe the effect after processing. Therefore, it is necessary to use video thumbnails to quickly preview video content and effects after adding special effects. video thumbnail Figure 1 Generally, a smaller size is used for storage (for example, a resolution of 122x68). A one-hour video typically has 3600 video thumbnails...
