Abstract

The invention provides a micro-video retrieval method and device based on a micro-video feature database. The micro-video retrieval method and device are mainly used for rapid retrieval of a huge number of micro-videos. The method comprises the steps that firstly, the micro-videos are preprocessed, key frames of the micro-videos are extracted, video frames are formed, and the correlation between each frame and the micro-videos is marked; then, the video frames serve as input of an own coding neural network, feature extraction is carried out through depth network learning, and a binary code base of each frame of the micro-videos is formed; finally, retrieval is carried out based on the Hamming distance k-nearest neighbor algorithm. Compared with the prior art, the depth learning technology is adopted, the manual interference process of video feature extraction is omitted, and rapid and effective retrieval can be carried out on the micro-videos.

Description

technical field [0001] The invention relates to the field of information retrieval, mainly refers to the establishment of a database server and the information reading and sorting in the database, in particular to a video image retrieval method and device. Background technique [0002] With the continuous improvement of mobile communication technology and terminal hardware level, the mobile Internet has developed rapidly, and the Internet has blown a spring breeze of reform. With the increasing popularity of the mobile Internet and smart phones, micro-videos have once again entered people's sights, and various related products have begun to appear on the market.
