Embodiment 1

[0032] figure 1 A schematic flowchart of a video frame selection method provided by an embodiment of the present application is shown. The execution subject of the video frame selection method is an electronic device, and the electronic device includes but is not limited to a computer, a server, a mobile terminal, or a camera. like figure 1 The video frame selection method shown is detailed as follows:

[0033] In S101, a current video frame is acquired.

[0034] In one embodiment, the current video frame is a newly generated video frame in the video stream captured in real time. In another embodiment, the current video frame is a video frame sequentially obtained from a multi-target video, where the multi-target video is a video shot in advance and includes at least two targets. Specifically, a decoding operation is performed on the multi-target video, and each time a frame of video frame is obtained by decoding, that is, the video frame of this frame is input as a current...

Embodiment 2

[0100] figure 2 A schematic structural diagram of an apparatus for selecting a video frame provided by an embodiment of the present application is shown. For the convenience of description, only parts related to the embodiment of the present application are shown:

[0101] The video frame selection device includes: an acquisition unit 21 , a first comprehensive quality score determination unit 22 , an update unit 23 , and a selection unit 24 . in:

[0102] The obtaining unit 21 is used for obtaining the current video frame.

[0103] The first comprehensive quality score determination unit 22 is configured to, if the current video frame includes all the first objects, determine the first comprehensive quality of the current video frame based on the quality of each of the first objects in the current video frame quality score; wherein, the first target is a target existing in the current candidate video frame; the candidate video frame has a corresponding pre-stored comprehen...

Embodiment 3

[0123] image 3 It is a schematic diagram of an electronic device provided by an embodiment of the present application. like image 3 As shown, the electronic device 3 of this embodiment includes a processor 30, a memory 31, and a computer program 32 stored in the memory 31 and executable on the processor 30, such as a video frame selection program. When the processor 30 executes the computer program 32, the steps in each of the foregoing video frame selection method embodiments are implemented, for example, figure 1 Steps S101 to S104 are shown. Alternatively, when the processor 30 executes the computer program 32, the functions of the modules / units in the foregoing device embodiments are implemented, for example, figure 2 The functions of units 21 to 24 are shown.

[0124] Exemplarily, the computer program 32 can be divided into one or more modules / units, and the one or more modules / units are stored in the memory 31 and executed by the processor 30 to complete the this...

Abstract

The invention is suitable for the technical field of video processing, and provides a video frame selection method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a current video frame; if the current video frame contains all the first targets, determining a first comprehensive quality score of the current video frame based on the quality of each first target in the current video frame; the candidate video frame has a corresponding pre-stored comprehensive quality score, and the pre-stored comprehensive quality score is a comprehensive quality score obtained based on the quality of each first target in the candidate video frame; according to a comparison result of the first comprehensive quality score and the pre-stored comprehensive quality score, updating the candidate video frame and the corresponding pre-stored comprehensive quality score; and if it is detected that the current preset period is reached, determining the latest candidate video frame as a first selected video frame. According to the embodiment of the invention, the video frame can be accurately and effectively selected.

Description

technical field [0001] The present application belongs to the technical field of video processing, and in particular, relates to a video frame selection method, device, electronic device and storage medium. Background technique [0002] At present, there are often three steps in video analysis: target detection, target tracking and target selection. Among them, target detection is used to find targets, target tracking is used to continuously track the found targets, and target selection is based on video. In each video frame, select the video frame with the best target capture quality for output. [0003] In the prior art, for a video with multiple targets, the target selection is preferably performed by sequentially selecting the optimal video frames corresponding to each target from the video for output. However, with the increase in the number of targets and the types of targets, the optimal video frames corresponding to each target have a high probability of being diffe...
