Abstract
Embodiments described herein provide a system for facilitating entity recognition. During operation, a camera associated with a computing device captures at least a first image of a to-be-recognized entity under a first imaging condition. The system adjusts the first imaging condition to achieve a second imaging condition, and the camera captures at least a second image under the second imaging condition. The system determines whether the to-be-recognized entity is a physical entity based on the captured first and second images and the first and second imaging conditions.
Claims20
A computer-implemented method for entity recognition, the method comprising:
- capturing, by a camera associated with a computing device, at least a first image of a to-be-recognized entity under a first imaging condition;
- adjusting the first imaging condition to achieve a second imaging condition;
- capturing at least a second image of the to-be-recognized entity under the second imaging condition;
- and
- determining whether the to-be-recognized entity is a physical entity based on the captured first and second images and the first and second imaging conditions.
A computer-implemented method for liveness detection of a user, the method comprising:
- in response to receiving, by a computing device, a request for detecting liveness of the user, capturing, by a camera associated with the computing device, at least a first image of the user under a first imaging condition;
- adjusting a setting of the computing device to achieve a second imaging condition;
- capturing at least a second image of the user under the second imaging condition;
- and
- determining liveness of the user based on the captured first and second images and the first and second imaging conditions.
A computer system, comprising:
- a processor;
- and
- a storage device coupled to the processor and storing instructions, which when executed by the processor cause the processor to perform a method for entity recognition, the method comprising:
- capturing, by a camera associated with a computing device, at least a first image of a to-be-recognized entity under a first imaging condition;
- adjusting the first imaging condition to achieve a second imaging condition;
- capturing at least a second image of the to-be-recognized entity under the second imaging condition;
- and
- determining whether the to-be-recognized entity is a physical entity based on the captured first and second images and the first and second imaging conditions.
