Claim 0:
1. A method for detection of arthritis based on temperature asymmetry estimation in joints, the method comprising:
recording, using an optical camera and a thermal camera, a first set of images including an optical image and a thermogram corresponding to a first joint of the joints, and a second set of images including an optical image and a thermogram corresponding to a second joint of the joints, the second joint being contralateral to the first joint;
receiving, by a processor, the first set of images and the second set of images;
aligning, by the processor, the optical image and the thermogram corresponding to first joint and aligning, by the processor, the optical image and the thermogram corresponding to the second joint;
identifying, by the processor, a location of the first joint in the first set of images, and identifying, by the processor, a location of the second joint in the second set of images;
comparing, by the processor, temperatures at specific locations in the first joint to temperatures at corresponding specific locations in the second joint to identify candidate locations at which a temperature of the first joint is greater than a temperature of the second joint by at least a predetermined temperature threshold; and
determining, by the processor, that arthritis of the first joint has occurred based on the temperatures at the candidate locations.
