Abstract
Systems, methods, etc., that assist a print examiner to thoroughly search and compare a print or substantial portion thereof against a known print database contained within an AFIS system. In certain embodiments, the prints can be definitively matched to a corresponding same print in the database. A result of a more thorough search and comparison can be a higher hit score and accuracy rate. In certain embodiments, the database comprises a candidate list of previously obtained prints to assist in the identification.
Claims26
A method of analyzing prints comprising:
- a) providing an at least 2-dimensional image of a print;
- b) subjecting the image to magnitude enhancement analysis such that at least one relative magnitude across at least a substantial portion of the print is depicted in an additional dimension relative to the at least 2-dimensions to provide a magnitude enhanced image such that additional levels of magnitudes are substantially more cognizable to a human eye compared to the 2-dimensional image without the magnitude enhancement analysis;
- c) displaying the enhanced image;
- and,
- d) manually reviewing the magnitude enhanced image to place at least one minutiae marker of the print.
A method of analyzing prints comprising:
- a) providing an at least 2-dimensional image of a print comprising minutiae markers determined by an automated minutia marker algorithm to provide automated minutiae markers;
- b) subjecting the image to magnitude enhancement analysis such that at least one relative magnitude across at least a substantial portion of the print is depicted in an additional dimension relative to the at least 2-dimensions to provide a magnitude enhanced image such that additional levels of magnitude are visible to a human eye compared to the 2-dimensional image without the magnitude enhancement analysis;
- c) displaying the enhanced image;
- and,
- d) manually reviewing the magnitude enhanced image to evaluate the correctness of the automated minutiae markers.
A method of analyzing prints comprising:
- a) providing an at least 2-dimensional image of a print;
- b) subjecting the image to magnitude enhancement analysis such that at least one relative magnitude across at least a substantial portion of the print is depicted in an additional dimension relative to the at least 2-dimensions to provide a magnitude enhanced image such that additional levels of magnitude are visible to a human eye compared to the 2-dimensional image without the magnitude enhancement analysis;
- c) dividing the magnitude enhanced image into a plurality of intensity levels;
- d) individually selecting at least one isolated intensity level;
- e) determining at least one AFIS marker from the isolated intensity level.
