Abstract

A system for high definition (HD) image recognition of criminals is disclosed. The system includes a plurality of cameras, an image recognition server, investigator user devices, a computing device, a database, and a network. At least one processor of the image recognition server is configured to receive a plurality of photographs of a first individual, perform image processing of the plurality of photographs to extract a first set of physical features, store feature data regarding the first set of physical features in the database, receive suspect data regarding a suspected individual from a first investigator user device, match the suspect data with the feature data stored in the database, and transmit an alert to the computing device in the prison, wherein the alert activates a mobile application on each investigator user device to display match data identifying the suspected individual as the first individual based on the feature data.

Claims

1. A system for high definition (HD) image recognition of criminals, the system comprising:

a plurality of cameras arranged on a motorized track in a booking room of a prison, wherein the motorized track is configured to facilitate movements of each camera, wherein each camera is configured to capture a photograph of a first individual during a booking of the first individual at the prison and prior to incarceration of the first individual at the prison, resulting in a plurality of photographs of the first individual;

an image recognition server comprising at least one processor and memory;

a computing device;

a database; and

a network that communicatively couples the plurality of cameras, the image recognition server, the computing device, and the database,

wherein the at least one processor of the image recognition server is configured to;

receive the plurality of photographs of the first individual captured by the plurality of cameras;

perform image processing of the plurality of photographs to extract a first set of physical features relating to the first individual; and

store feature data regarding the first set of physical features in the database, wherein the feature data is associated with the first individual.

2. The system of claim 1, wherein the plurality of cameras comprise high definition (HD) cameras arranged in the booking room of the prison and configured to capture the plurality of photographs of the first individual from a plurality of angles in the booking room of the prison.

3. The system of claim 1, wherein performing image processing of the plurality of photographs comprises:

analyzing pixels of each photograph in the plurality of photographs;

detecting a region of pixels in at least one of the plurality of photographs that differ in color and intensity values by a predetermined threshold value from an adjacent region of pixels; and

identifying the region of pixels as the first set of physical features.

4. The system of claim 3, wherein the first set of physical features comprises data regarding visual attributes of the first individual, wherein the visual attributes of the first individual comprise tattoos, piercing, scars, or markings on a body of the first individual.

5. The system of claim 1, wherein the at least one processor is further configured to:

apply a cryptographic hashing of the feature data of the first individual; and

store the feature data regarding the first set of physical features in the database based on the cryptographic hashing.

6. The system of claim 1, wherein each of the plurality of cameras is further configured to detect a height of the first individual, and wherein the motorized track is further configured to shift a position of one or more of the plurality of cameras by a predetermined distance based on the height of the first individual.

7. An image recognition server for identifying an individual in a prison, the image recognition server comprising:

a database storing booking data for a plurality of criminals;

a network interface device configured to communicate with the database, a plurality of cameras arranged on a motorized track in a booking room of the prison, and a computing device in the prison, wherein the motorized track is configured to facilitate movements of each camera; and

at least one processor configured to;

receive a plurality of photographs captured by the plurality of cameras during a booking of the individual at the prison and prior to incarceration of the individual at the prison, wherein each photograph depicts the individual;

extract a set of physical features of the individual from the plurality of photographs by performing image processing of each photograph; and

store feature data comprising the set of physical features in the database by cryptographic hashing, wherein the feature data is associated with the individual.

8. The image recognition server of claim 7, wherein the plurality of cameras comprises four high definition (HD) cameras that are mounted on a track arranged in the booking room of the prison.

9. The image recognition server of claim 8, wherein the plurality of photographs captured by the plurality of cameras are captured at predetermined locations along the track arranged in the booking room of the prison.

10. The image recognition server of claim 7, wherein extracting the set of physical features comprises:

analyzing pixels of each photograph in the plurality of photographs;

detecting regions of pixels in each photograph that differ in color and intensity values by predetermined threshold values from adjacent regions of pixels; and

identifying the regions of pixels in each photograph as the set of physical features.

11. The image recognition server of claim 7, wherein the set of physical features of the individual comprise data regarding visual attributes of the individual.

12. The image recognition server of claim 11, wherein the visual attributes of the individual comprise at least one of tattoos, piercings, scars, or markings on a body of the individual.

13. The image recognition server of claim 7, wherein the storing the feature data by cryptographic hashing comprises:

generating a hash value for each physical feature in the set of physical features, wherein the hash value comprises a fixed-length value; and

storing the hash value for each physical feature in the database.

14. A method for performing high definition (HD) image recognition of criminals, the method comprising:

capturing, by a plurality of cameras arranged on a motorized track in a booking room of a prison, a plurality of photographs of an individual during a booking of the individual at the prison and prior to incarceration of the individual at the prison, wherein the motorized track is configured to facilitate movements of each camera;

receiving, from the plurality of cameras by an image recognition server, the plurality of photographs of the individual;

extracting, by at least one processor of the image recognition server, a set of physical features of the individual from at least one photograph by performing image processing of the at least one photograph; and

storing feature data regarding the set of physical features of the individual in a database that stores booking data for a plurality of criminals, wherein the feature data is associated with the individual in the database.

15. The method of claim 14, wherein the plurality of cameras comprise high definition (HD) cameras configured to capture the plurality of photographs of the individual from a plurality of angles in the booking room of the prison.

16. The method of claim 14, wherein the extracting of the set of physical features comprises:

analyzing, by the at least one processor of the image recognition server, pixels of the at least one photograph;

detecting, by the at least one processor of the image recognition server, regions of pixels in the at least one photograph that differ in color and intensity values by predetermined threshold values from adjacent regions of pixels; and

identifying, by the at least one processor of the image recognition server, the regions of pixels in the at least one photograph as the set of physical features.

17. The method of claim 14, further comprising:

applying, by the at least one processor of the image recognition server, a cryptographic hashing of the feature data of the individual; and

storing the feature data regarding the set of physical features in the database based on the cryptographic hashing.

18. The method of claim 14, wherein the set of physical features comprises data regarding visual attributes of the individual, wherein the visual attributes of the individual comprise at least one of tattoos, piercing, scars, or markings on a body of the individual.

19. The method of claim 14, further comprising:
