Problems solved by technology

However, for video files, at present, only keywords such as the name of the video file can be used to search, and the search result is often a whole section of video corresponding to the keyword, and it is impossible to search for specific content in a video file. For example, surveillance cameras are installed in various occasions such as roads, residences, and shopping malls. When users need to find a specific person or scene in a surveillance video captured by a surveillance camera, they can only pass through many lengthy video recordings. Continuously watch to find out what you need, facing a large number of video files, the search task is difficult to complete

Abstract

A video search method includes: displaying an input interface; building a model image as the key image according to at least one input parameters if at least one parameter is input through the input interface; extracting information as to features of the key image; comparing the features of the key image with features in each frame of each stored video file to determine whether the features shown in one or more frames of each stored video file match with the features of the key images; determining that a video file is a target video file if at least one frame of the video file matches with the features of the key image; and presenting the target video files or other processing. A computing device and a storage medium for searching video files are also described.

Description

technical field [0001] The invention relates to a file retrieval system and a retrieval method, in particular to a video file retrieval system and a retrieval method. Background technique [0002] With the development of network technology, people can quickly find the text and picture content they need in the network through search engines. However, for video files, at present, only keywords such as the name of the video file can be used to search, and the search result is often a whole section of video corresponding to the keyword, and it is impossible to search for specific content in a video file. For example, surveillance cameras are installed in various occasions such as roads, residences, and shopping malls. When users need to find a specific person or scene in a surveillance video captured by a surveillance camera, they can only pass through many lengthy video recordings. Continuously watch to find out what you need. Faced with a large number of video files, the sear...
