Abstract
The invention relates to the face search technology, in particular to a device and a method for face search in videos. The device comprises a preprocessing module, a face detection module, a face extraction module, a face recognition module and a face indexing and association module which are connected with a system bus module respectively, the system bus module is connected with a data interface module, and the data interface module is connected with a display module. The method includes: obtaining standard video data for preprocessing, conducting face detection on preprocessed data, conducting a face recognition algorithm on key frames to obtain related face information, filing extracted and recognized face images, and correlating the filed images and the starting and ending time of the filed images in the videos. The device and the method effectively solve the problem of browsing and replaying target videos with specific face information fast and accurately from massive video monitoring data; reduces the work load of the work staff as well as operation time, and improves the work efficiency.
Description
Technical field
The present invention relates to face retrieval technology, be specially a kind of device for face retrieval in video.
Background technology
Along with video monitoring system is in the large-scale application in the field such as security protection, commercial production, the video data of magnanimity in system, is had to store all the time, the active situation of these video essential records personnel.In actual applications, staff usually wishes, in the video data of magnanimity, to find occurred target person easily.But want realization to find qualified video, tradition is too simple based on the retrieval mode of control point and time point, after staff recalls the monitor video of somewhere time period, just need artificially to retrieve for examination video pictures omnidistancely.So, very waste of manpower and the time, and also personnel participate in retrieving for examination for a long time, and the possibility missing the appearance of target person is very big.
Summary of the invention
For the problems referred to above, the invention provides a kind of device and method for face retrieval in video, concrete technical scheme is:
