Abstract

Systems (100) and methods (300, 400) for efficient comparative non-spatial image data analysis. The methods involve ranking a plurality of non-spatial images (1011, 1050, 1231, 1539, 0001, 0102, 0900, 1678, 0500, 0020, 0992, 1033, 1775, 1829) based on at least one first attribute thereof; generating a screen page (1102-1106) comprising an array (1206) defined by a plurality of cells (1208) in which at least a portion of the non-spatial images are simultaneously presented; and displaying the screen page in a first GUI window (802) of a display screen. Each cell comprises only one non-spatial image. The non-spatial images are presented in an order defined by the ranking thereof.

Claims

1. A method for efficient comparative non-spatial image data analysis, comprising:

identifying non-spatial images from a plurality of non-spatial images with first match scores equal to or greater than a pre-defined threshold value, where each first match score indicates an amount of matching between content of a respective non-spatial image of the non-spatial images and content of a reference non-spatial image;

ranking, by at least one electronic circuit, the non-spatial images which were identified from the plurality of non-spatial images, where the ranking is based on at least one first attribute of the non-spatial images, and said first attribute comprises a second match score that indicates at least one of (a) how many minutiae points match each other or are common between at least two finger print images and (b) how many common minutiae points of the at least two finger print images have the same number of ridges connected thereto;

generating, by said electronic circuit, a screen page comprising an array defined by a plurality of cells in which at least two images of said plurality of non-spatial images are simultaneously presented in an order defined by said ranking thereof;

displaying, by said electronic circuit, said screen page in a first GUI window of a display screen;

wherein each of said plurality of cells comprises only one of said non-spatial images.

2. The method according to claim 1, wherein said plurality of non-spatial images are further ranked based on a second attribute that comprises a computed metric that specifies an amount of content of the respective non-spatial image of said plurality of non-spatial images that matches content of the reference non-spatial image.

3. The method according to claim 1, further comprising displaying in said first GUI window at least said first attribute associated with a selected one of said plurality of non-spatial images that is presented therein.

4. The method according to claim 1, further comprising changing content of a second GUI window to include a non-spatial image of a selected one of said plurality of non-spatial images that is presented in said first GUI window.

5. The method according to claim 1, further comprising replacing a selected image of said plurality of non-spatial images that is presented in said first GUI window with an edited version of said selected image.

6. The method according to claim 1, further comprising sorting or filtering said plurality of non-spatial images based on at least one second attribute thereof.

7. The method according to claim 6, wherein said second attribute comprises a print type, a number of minutiae, minutiae characteristics, a number of ridges, a number of broken ridges, a presence of a core in a fingerprint, an area of a fingerprint, a contrast of an image, a brightness of an image, an intensity of an image, a number of pores that are in a fingerprint, or a number of pores of a fingerprint that were filled.

8. The method according to claim 1, further comprising toggling content of one particular cell of the plurality of cells contained in the displayed screen page between two different non-spatial images, wherein said two different non-spatial images comprise a candidate fingerprint image and a reference fingerprint image.

9. The method according to claim 1, further comprising toggling content of one particular cell of the plurality of cells contained in the displayed screen page between two different non-spatial images, wherein said two different non-spatial images comprise color coding indicating differences and similarities between content thereof.

10. The method according to claim 1, further comprising adding a mark or annotation to at least one of the plurality of non-spatial images in response to a user-software interaction.

11. The method according to claim 1, further comprising adding a mark or annotation to all of the plurality of non-spatial images that precede or succeed a selected one of the plurality of non-spatial images in a ranked order or a sorted order.

12. The method according to claim 1, further comprising exporting at least one of the plurality of non-spatial images that has a mark or annotation added thereto to a file or table.

25. The method according to claim 1, wherein the minutiae comprises at least one of ridge endings, spurs, and bifurcations.

26. The method according to claim 1, further comprising:

receiving a user input for selectively toggling content of one particular cell of the plurality of cells contained in the displayed screen page between two different non-spatial images; and

in response to the reception of the user input, toggling the content of the particular cell between the two different non-spatial images, while content of all other cells of the screen page remains unchanged.

13. A system for efficient comparative non-spatial image data analysis, comprising:

at least one electronic circuit configured to;

identify non-spatial images from a plurality of non-spatial images with first match scores equal to or greater than a pre-defined threshold value, where each first match score indicates an amount of matching between content of a respective non-spatial image of the non-spatial images and content of a reference non-spatial image;

rank the non-spatial images which were identified from the plurality of non-spatial images, where the ranking is based on at least one first attribute of the non-spatial images, and said first attribute comprises a second match score that indicates at least one of (a) how many minutiae points match each other or are common between at least two finger print images and (b) how many common minutiae points of the at least two finger print images have the same number of ridges connected thereto;

generate a screen page comprising an array defined by a plurality of cells in which at least two images of said non-spatial images are simultaneously presented in an order defined by said ranking thereof; and

display said screen page in a first GUI window of a display screen;

wherein each of said plurality of cells comprises only one of said plurality of non-spatial images.

14. The system according to claim 13, wherein said plurality of non-spatial images are further ranked by a second attribute that comprises a computed metric that specifies an amount of content of the respective non-spatial image of said plurality of non-spatial images that matches content of the reference non-spatial image.

15. The system according to claim 13, wherein said electronic circuit is further configured to display in said first GUI window at least said first attribute associated with a selected one of said plurality of non-spatial images that is presented therein.

16. The system according to claim 13, wherein said electronic circuit is further configured to change content of a second GUI window to include a non-spatial image of a selected one of said plurality of non-spatial images that is presented in said first GUI window.

17. The system according to claim 13, wherein said electronic circuit is further configured to replace a selected image of said plurality of non-spatial images that is presented in said first GUI window with an edited version of said selected image.

18. The system according to claim 13, wherein said electronic circuit is further configured to sort or filter said plurality of non-spatial images based on at least one second attribute thereof.

19. The system according to claim 18, wherein said second attribute comprises a print type, a number of minutiae, minutiae characteristics, a number of ridges, a number of broken ridges, a presence of a core in a fingerprint, an area of a fingerprint, a contrast of an image, a brightness of an image, an intensity of an image, a number of pores that are in a fingerprint, or a number of pores of a fingerprint that were filled.

20. The system according to claim 13, further comprising toggling content of a particular cell contained in the displayed screen page between two different non-spatial images, wherein said two different non-spatial images comprise a candidate fingerprint image and a reference fingerprint image.
