Abstract
A system and method for automated print identification is described. In particular, the method includes providing an active search record, arranging the prints of the active search record according to print quality to generate a filtered active file database, providing the filtered active file database as the input to a match algorithm, detecting a print correlation corresponding to a print contained in the active file database, determining if a print match has been made, determining the strength of a match if a print match has been made, and determining the active search file record to be added into the active database or the matched active file records to be updated.
Claims22
A method for automated print identification, said method comprising the steps of:
- providing an active search record comprising a plurality of prints;
- arranging the prints of said active search record according to print quality to generate a filtered active file record database comprising a plurality of active file records;
- providing said filtered active file record database as the input to a match algorithm;
- detecting a print correlation corresponding to a print contained in said filtered active file record database;
- determining if a print match has been made;
- determining the strength of a match if a print match has been made;
- determining whether the active search record is to be added into the filtered active file record database;
- and
- determining whether at least one matched active file record is to be modified;
- and
- the method further comprising at least one of the steps of:
- detecting missing fingerprints in accordance with at least one of image dynamic range and match score;
- detecting whether a print is at least one of registered in a wrong box or registered in a wrong sequence in accordance with match score;
- detecting whether a print registers as a duplicate in accordance with match score;
- at least one of replacing and substituting a print in accordance with at least one of print quality and match score;
- grading each print in accordance with at least one of print quality and match score between a slap print and a corresponding roll print;
- selecting the best quality prints from an active search record and identified active file records to form said active file record;
- selecting the best quality prints from at least one of slap prints and rolled prints to form said active search record;
- linking an active file record to an identity file records via a link list;
- and
- compiling an active file record for at least a subset of best quality prints from said link list corresponding to substantially similar identity file records.
