Embodiment Construction
[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0034] see figure 1 , figure 2 The object of the high-definition video content retrieval method in this embodiment is the retrieval of high-definition video content for sea vessel channel cruising. Of course, the method of the present invention is not limited to this embodiment. Please refer to figure 1 , the implementation of high-definition video content retrieval for channel cruising of sea vessels is implemented according to the following procedures.
[0035] (1) Preliminary analysis of the obtained high-definition video of ship cruising, dividing individual information frames and group information frames; according to the information of interest and the complexity of the sea scene when the ship is cruising at sea, the threshold of the moving target can be set to 1. That is, when there is one or less than one moving object in ...

The invention discloses a method for retrieving a high-definition video content, which is characterized by comprising the following steps of: (1) dividing the high-definition video content into a group information frame and an individual information frame initially, and storing the corresponding video frame information to establish a video index file; (2) constructing a high-level semantic library, and establishing a semantic library comprising various events and a plurality of pieces of target information by using the conventional knowledge; (3) performing video retrieval on an individual information frame according to the high-level semantic library, and establishing an individual information content index file; (4) performing the video retrieval on a group information frame according to the high-level semantic library, and establishing a group information content index file; and (5) merging the individual information content index file and the group information content index file to form an index file for the entire video content.
Description
technical field [0001] The present invention relates to the technical field of video retrieval, in particular to a high-definition video content retrieval method and system. Background technique [0002] With the development of multimedia technology and the progress of manufacturing and processing technology, the video available to people has been greatly improved and improved both in quantity and quality. At the same time, people's requirements for the clarity and detailed information of video images are also increasing, and ordinary standard-definition videos cannot meet people's needs. High-definition video has the characteristics of good picture quality, high picture definition, and highlighting detailed information, which are exactly what people need, so gradually high-definition video will become the mainstream. Then, in the face of a large amount of high-definition video data, how people can get the content they are interested in without spending too much time has be...
