Problems solved by technology

In the related technology, the video file can be manually downloaded, and after a complete viewing, the specified scene or character rich segment can be recorded, and then the video screenshot can be realized through video editing software. This method is seriously affected by human subjective factors, lacks objectivity, and artificial Downloading videos and watching them is inefficient
It is also possible to screenshot the video frame by frame through a computer program, and manually browse to select an image that meets the expected content, but the storage cost of capturing frame by frame is high, and there are also problems of insufficient objectivity and low efficiency

Abstract

The present disclosure relates to an image generation method and device. The method includes: extracting frames from a video to obtain a video frame image; extracting feature information of the video frame image; selecting a target image in the video frame image according to the feature information, and determining The playback time corresponding to the selected target image; taking a screenshot of the video according to the playback time to generate a screenshot image corresponding to the playback time. According to the image generation method of the embodiment of the present disclosure, by extracting frames from the video and processing the video frame image, the playback time corresponding to the target image can be determined, and a screenshot can be taken according to the playback time, realizing the automatic generation of the screenshot image, The efficiency of generating the screenshot image is improved, and the feature information of the video frame image is used to select the target image, so that the selection of the target image is more objective.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to an image generation method and device. Background technique [0002] During the processing of the video image, it may be necessary to take a screenshot of the image in the video, and obtain a high-definition screenshot as a cover or poster. In the related technology, the video file can be manually downloaded, and after a complete viewing, the specified scene or character rich segment can be recorded, and then video screenshots can be realized through video editing software. This method is seriously affected by human subjective factors, lacks objectivity, and artificial Downloading videos and watching them is inefficient. It is also possible to screenshot the video frame by frame through a computer program, and manually browse to select an image that meets the expected content, but the storage cost of capturing frame by frame is high, and there are also problems of in...
