1. A system comprising:

  • a database storage;

    at least one processor; and

    at least one memory coupled to the at least one processor having stored thereon instructions which, when executed by the at least one processor, causes the at least one processor to perform operations comprising;

    managing, in the database storage, a watch list that includes sorted biometric data for persons in the watch list and associations to additional biometric data for the persons in the watch list;

    accessing multiple images of a potential suspect to use to determine if the potential suspect matches one of the persons in the watch list;

    determining at least one criterion relevant to the multiple images of the potential suspect based on at least one of sensor and camera data;

    selecting two or more images to use in pre-processing based on the at least one criterion;

    controlling parallel pre-processing of the selected two or more images of the potential suspect to enhance a quality of each of the selected two or more images;

    based on the pre-processing, determining an image of the potential suspect to use in matching against the watch list;

    using the determined image of the potential suspect to search the sorted biometric data included in the watch list;

    identifying a subset of persons from the watch list based on the search of the sorted biometric data included in the watch list;

    controlling parallel analysis of the determined image of the potential suspect against biometric data associated with the subset of persons in the watch list;

    determining whether the potential suspect matches a person in the subset of persons in the watch list using a result of the controlled parallel analysis of the determined image of the potential suspect against the biometric data associated with the subset of persons in the watch list; and

    outputting a result based on the determination of whether the potential suspect matches a person in the subset of persons in the watch list.
