Abstract

A method, system and computer program product for measuring non-uniformity noise produced in images or videos (e.g., infrared images or videos). Images or videos, such as infrared images or videos, are captured. A model of scene statistics (statistical model of pictures, images or videos representative of pictures, images or videos, respectively, that are captured of the physical world) is utilized to measure the non-uniformity noise in the captured images or videos by exploiting exhibited characteristics for non-uniformity noise in the captured images or videos. A number signifying a magnitude of non-uniformity for each image or video frame is then generated. In this manner, non-uniformity noise produced in images or videos is measured.

First claim

The invention claimed is:

1. A method for measuring non-uniformity noise produced in infrared images or videos, the method comprising:
capturing infrared images or videos;
utilizing, by a processor, a model of scene statistics to measure said non-uniformity noise in said captured infrared images or videos by exploiting exhibited characteristics for non-uniformity noise in said captured infrared images or videos; and
generating a number signifying a magnitude of non-uniformity for each infrared image or video frame.

2. The method as recited in claim 1 further comprising:
accumulating said generated numbers to provide a summary of said non-uniformity in an entire infrared video.

3. The method as recited in claim 1 , wherein said exhibited characteristics comprise a shape and a variance.

4. The method as recited in claim 1 , wherein said scene statistics are natural scene statistics.

5. A computer program product for measuring non-uniformity noise produced in infrared images or videos, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code comprising the programming instructions for:
capturing infrared images or videos;
utilizing a model of scene statistics to measure said non-uniformity noise in said captured infrared images or videos by exploiting exhibited characteristics for non-uniformity noise in said captured infrared images or videos; and
generating a number signifying a magnitude of non-uniformity for each infrared image or video frame.

6. The computer program product as recited in claim 5 , wherein the program code further comprises the programming instructions for:
accumulating said generated numbers to provide a summary of said non-uniformity in an entire infrared video.

7. The computer program product as recited in claim 5 , wherein said exhibited characteristics comprise a shape and a variance.

a processor coupled to the memory unit, wherein the processor is configured to execute the program instructions of the computer program comprising:
capturing infrared images or videos;
utilizing a model of scene statistics to measure said non-uniformity noise in said captured infrared images or videos by exploiting exhibited characteristics for non-uniformity noise in said captured infrared images or videos; and
generating a number signifying a magnitude of non-uniformity for each infrared image or video frame.

10. The system as recited in claim 9 , wherein the program instructions of the computer program further comprise:
accumulating said generated numbers to provide a summary of said non-uniformity in an entire infrared video.

11. The system as recited in claim 9 , wherein said exhibited characteristics comprise a shape and a variance.

12. The system as recited in claim 9 , wherein said scene statistics are natural scene statistics.

13. A method for measuring non-uniformity noise produced in images or videos, the method comprising:
capturing images or videos;

generating a number signifying a magnitude of non-uniformity for each image or video frame.

14. The method as recited in claim 13 further comprising:
accumulating said generated numbers to provide a summary of said non-uniformity in an entire video.

15. The method as recited in claim 13 , wherein said exhibited characteristics comprise a shape and a variance.

16. The method as recited in claim 13 , wherein said scene statistics are natural scene statistics.

17. The method as recited in claim 13 , wherein said captured images or videos are one of the following: X-ray images or videos, magnetic resonance imaging images or videos, millimeter wave images or videos and visible light images or videos.

18. A computer program product for measuring non-uniformity noise produced in images or videos, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code comprising the programming instructions for:
capturing images or videos;
utilizing a model of scene statistics to measure said non-uniformity noise in said captured images or videos by exploiting exhibited characteristics for non-uniformity noise in said captured images or videos; and
generating a number signifying a magnitude of non-uniformity for each image or video frame.

19. The computer program product as recited in claim 18 , wherein the program code further comprises the programming instructions for:
