Abstract
The invention relates to a method for comparing photographs and videos based on a computer system of human face identification. The method comprises the following steps: (1) conducting face detection for a photograph of a front stage, extracting a human face, extracting human facial features and forming a human facial template A; (2) analyzing video data of a back stage to obtain a video frame; (3) conducting the face detection for the obtained video frame, extracting a human face, extracting human facial features and forming a human facial template B; (4) comparing the template A and the template B to obtain a similarity; and (5) when the similarity is larger than a set value, the faces in the photograph and the video are supposed to belong to the same person; when the similarity is less than the set value, the comparison between the next video frame and the photograph is followed. With the technical proposal, the method has the advantages that: the method is provided for comparing the photograph of the front stage and the video of the back stage so as to search a similar person in the video according to the human facial features in the photograph, thereby improving the work efficiency of the human face identification.
Description
Technical field
The present invention relates to the correlative technology field of computer face identification, particularly a kind of photograph video comparison method.
Background technology
In the correlative technology field of computer face identification, have only photo template comparison in foreground photo template and the background data base and the photo template ratio in foreground video and the background data base now.There is not the comparison of foreground photo template and backstage video.And in real work, photo and video data are arranged sometimes, and need in video data, search for the people similar with photo, just need the comparison method of a kind of foreground photo and backstage video this moment.
Summary of the invention
The objective of the invention is for a kind of photograph video comparison method is provided, to finish in the video data search people's similar function with photo.
For achieving the above object, the present invention has adopted following technical scheme:
The invention discloses a kind of photograph video comparison method, the computer system based on recognition of face is characterized in that: specifically may further comprise the steps:
1) photo to the foreground carries out the detection of people's face, extracts people's face, extracts face characteristic, forms face template A;
2) video data on backstage is resolved, obtain frame of video;
3) video requency frame data that obtains is carried out people's face and detect, extract people's face, extract face characteristic, form face template B;
4) template A and template B are compared, obtain similarity;
That 5) occur in similarity is thought photo and video during greater than setting value is same individual; When similarity then continues the comparison of next frame of video and photo during less than setting value.
If what occur is same man-hour, confirm that by the user back selects to proceed comparison or termination is compared in similarity is thought photo and video during greater than setting value.
Owing to adopted above scheme, the beneficial effect that the present invention is possessed is: the comparison method that a kind of foreground photo and backstage video are provided, realized in video, searching for the people's similar function, improved the work efficiency of recognition of face to personage's facial characteristics in the photo.
Embodiment
Below in conjunction with embodiment the present invention is further described.
A kind of photograph video comparison method, the computer system based on recognition of face is characterized in that: specifically may further comprise the steps:
1) photo to the foreground carries out the detection of people's face, extracts people's face, extracts face characteristic, forms face template A;
2) video data on backstage is resolved, obtain frame of video;
3) video requency frame data that obtains is carried out people's face and detect, extract people's face, extract face characteristic, form face template B;
4) template A and template B are compared, obtain similarity;
5) if what occur is same man-hour, confirm that by the user back selects to proceed comparison or termination is compared in similarity is thought photo and video during greater than setting value; When similarity then continues the comparison of next frame of video and photo during less than setting value.
This method has realized searching for the people's similar to personage's facial characteristics in the photo function in video, improved the work efficiency of recognition of face.
Claims (2)
1, a kind of photograph video comparison method, the computer system based on recognition of face is characterized in that: specifically may further comprise the steps:
