Embodiment Construction
[0046] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0047] refer to figure 1 , which shows a flowchart of a method for selecting an insertion point position in a video advertisement according to an embodiment of the present invention, and the method may specifically include:
[0048] Step 101 , by comparing the similarity between adjacent video frames in the video, find the video shot switching point in the video.
[0049] The shot switching point in the video can be obtained by comparing the similarity between video frames. By calculating the similarity between two adjacent video frames in the video, the change of the similarity value is further compared. When the similarity is small, the shot can be considered A cut occurs, in other words, a video shot cut point refers to a posi...

The invention provides a method and a device for selecting a position to insert a point in a video advertisement. The method comprises steps of searching a video shot switching point in the video by comparing the similarity between adjacent video frames in the video, searching a mute point area in the video according to the video audio frequency information, performing sorting on the video shot switching points with the most front queuing time in the mute point, and choosing the video shot switching point, the time interval of which accords with the preset condition after the sorting, as a inserting point in the video advertisement. The automatic selection method provided by the invention can realize the high efficiency processing on the large batch of the videos, can reduce the choosing labor of the worker and reduce the labor cost.
Description
technical field [0001] The invention relates to the field of video technology, in particular to a method for selecting an insertion point position in a video advertisement, and a device for selecting an insertion point position in a video advertisement. Background technique [0002] In TV and video websites, it is often necessary to insert advertisements during video playback, and the time point at which advertisements are inserted in the video is called the middle insertion point. [0003] In the current video editing work, the position of the interpolation point mainly relies on manual selection. With the increase of the number of videos, due to the low efficiency of manual selection, it cannot meet the needs of mass processing of videos. Therefore, it is necessary to provide a mechanism for automatically selecting the insertion position of advertisements to achieve efficient processing of mass videos. Contents of the invention [0004] The invention provides a method a...
