Abstract
An image management method includes: after a video stream sent by a camera is obtained, recognizing a face image in the video stream through face recognition; comparing the image with a face image that is in an area in which the camera is located in a database; and if the comparison fails, expanding the area in which the camera is located around, and then comparing the face image with face images in an area obtained after the area in which the camera is located is expanded.
Claims20
An image management method, the method comprising:
- receiving image data sent by a first camera, the image data comprising at least one face image, and the at least one face image comprising a first face image;
- obtaining the first face image in the image data;
- comparing the first face image with a face image in a first area in a database, the database being a database storing face images in each area, and the first area being an area in which at least one camera comprising the first camera is located;
- based upon determining that the face image in the first area in the database does not comprise a face image of a photographed person corresponding to the first face image, comparing the first face image with face images in a second area in the database, the second area being an area obtained by expanding around the first area, the second area being an area in which a plurality of cameras comprising the first camera are located, and a quantity of cameras in the second area being greater than a quantity of cameras in the first area;
- and
- based upon determining that the face images in the second area in the database comprise a face image of the photographed person corresponding to the first face image, clustering the first face image and the face image of the photographed person corresponding to the first face image.

A computing device, the computing device comprising:
- a memory storing computer executable instructions;
- and
- a processor connected to the memory and configured to execute the computer executable instructions to perform operations comprising:
- receiving image data sent by a first camera, the image data comprising at least one face image, and the at least one face image comprising a first face image;
- obtaining the first face image in the image data;
- comparing the first face image with a face image in a first area in a database, the database being a database storing face images in each area, and the first area being an area in which at least one camera comprising the first camera is located;
- based upon determining that the face image in the first area in the database does not comprise a face image of a photographed person corresponding to the first face image, comparing the first face image with face images in a second area in the database, the second area being an area obtained by expanding around the first area, the second area being an area in which a plurality of cameras comprising the first camera are located, and a quantity of cameras in the second area being greater than a quantity of cameras in the first area;
- and
- based upon determining that the face images in the second area in the database comprise a face image of the photographed person corresponding to the first face image, clustering the first face image and the face image of the photographed person corresponding to the first face image.

A non-transitory computer-readable storage medium, the computer-readable storage medium storing a computer program, and the computer program being configured such that, when executed on a computer, the computer is enabled to implement a method comprising:
- receiving image data sent by a first camera, the image data comprising at least one face image, and the at least one face image comprising a first face image;
- obtaining the first face image in the image data;
- comparing the first face image with a face image in a first area in a database, the database being a database storing face images in each area, and the first area being an area in which at least one camera comprising the first camera is located;
- based upon determining that the face image in the first area in the database does not comprise a face image of a photographed person corresponding to the first face image, comparing the first face image with face images in a second area in the database, the second area being an area obtained by expanding around the first area around, the second area being an area in which a plurality of cameras comprising the first camera are located, and a quantity of cameras in the second area being greater than a quantity of cameras in the first area;
- and
- based upon determining that the face images in the second area in the database comprise a face image of the photographed person corresponding to the first face image, clustering the first face image and the face image of the photographed person corresponding to the first face image.
