Abstract

The invention relates to the field of artificial intelligence, and provides a PPT video segment extraction method and device, equipment and a medium. According to the PPT video segment extraction method and device, the equipment and the medium, one or more key point short videos can be automatically clipped; users can be facilitated to quickly understand video subjects; important reference is provided for later forecast production and the like; a machine learning method is effectively used to establish feature engineering for video analysis; on the basis, coarse segmentation is carried out onan audio file; feature weights are increased through global matching and local matching; fine-grained division is carried out on chapters; and therefore, a large number of training models are not needed, personalized customization can be carried out for a certain vertical field, and operability is higher. The invention also relates to a block chain technology. At least one short video can be stored in a block chain.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a PPT video segment extraction method, device, equipment and medium. Background technique [0002] With the accelerated pace of urban life, users usually want to know the most exciting clips in a short time when watching videos. For example, they can create unforgettable movie trailers through editing, compositing, special effects, etc. Or in some online open courses, use technical means to extract effective information to form short videos, so that users can understand the essence of the video more intuitively. [0003] Currently popular video editing or editing software mainly relies on manual participation in the segmentation of video clips. Usually, the user selects the appropriate frames after watching the video, and finally stitches them together. This requires the editor to fully understand the video content and accurately locate key information. N...
