Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a device may receive, from a fingerprint scanner, fingerprint scan data associated with an image that depicts a scanned fingerprint of a user; process, using a model-based iterative reconstruction (MBIR) model, the fingerprint scan data to generate an enhanced image associated with the image; and perform, based at least in part on the enhanced image, a match analysis to authenticate the user. Numerous other aspects are provided.
Claims30
A method, comprising:
- receiving, by a device and from a fingerprint scanner, fingerprint scan data associated with an image that depicts a scanned fingerprint of a user;
- processing, by the device and using a model-based iterative reconstruction (MBIR) model, the fingerprint scan data to generate an enhanced image associated with the image;
- and
- performing, by the device and based at least in part on the enhanced image, a match analysis associated with authenticating the user.
A device for wireless communication, comprising:
- a memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- train a signal model to process an image based at least in part on an image quality metric associated with the image;
- configure a sensor model based at least in part on calibration information associated with a fingerprint scanner;
- and
- configure an optimization model to enhance the image based at least in part on the signal model and the sensor model.
A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a device, cause the device to:
- receive, from a fingerprint scanner, fingerprint scan data associated with an image that depicts a scanned fingerprint of a user;
- process, using a model-based iterative reconstruction (MBIR) model, the fingerprint scan data to generate an enhanced image associated with the image;
- and
- perform, based at least in part on the enhanced image, a match analysis associated with authenticating the user.
An apparatus for wireless communication, comprising:
- means for receiving, from a fingerprint scanner, fingerprint scan data associated with an image that depicts a scanned fingerprint of a user;
- means for processing, using a model-based iterative reconstruction (MBIR) model, the fingerprint scan data to generate an enhanced image associated with the image;
- and
- means for performing, based at least in part on the enhanced image, a match analysis associated with authenticating the user.
