Abstract: A method for automatic correction and generation of facial images includes storing, by a computer system, multiple constraints specifying an image quality. The computer system receives a first image of a face of a user from a computer device. The computer system determines that the first image of the face of the user violates at least one constraint of the multiple constraints specifying the image quality. Responsive to the determining that the first image of the face of the user violates the at least one constraint, the computer system generates a second image of the face of the user based on the first image of the face of the user and the at least one constraint, such that the second image of the face of the user satisfies the at least one constraint. A display device of the computer system displays the second image of the face of the user.

Abstract: Provided herein are systems and methods for automatically limiting video surveillance collection to authorized uses and authorized users. To achieve this control, the authorization system can be configured to manage and secure a plurality of crypto keys associated with encrypting a plurality of corresponding video footages and release a crypto key for a video footage at approved times to limit user access to the video footage. In particular, the surveillance system can generate a video collection including a copy of portions of a received video footage that include one or more approved events from a watchlist of a user. Thereafter, the video footage can be encrypted by a first key managed by the authorization system and prevents the user from accessing video content of the video footage once encrypted. Accordingly, the user may be limited to accessing the video collection and not all the portions in the encrypted video footage.

Abstract: A list of possible mated minutiae in a reference fingerprint and a search fingerprint is identified. The list of possible mated minutiae is divided into different groups of mated minutiae using pose grouping based on rigid transformation parameters. For each group, the possible mated minutiae are filtered to get a set of consistent mated minutiae pairs having similar rigid transformation. The topological consistency between groups is determined. If any two groups are topologically consistent to each other, they are merged to form a (virtual) larger group. A non-linear transformation parameters are estimated from the mated minutiae in the merged group. The overall similarity of mated and non-mated minutiae in the overlapping area is determined after non-linear alignment of the two fingerprints, and the maximum similarity is output as the final similarity score between two fingerprints.
