Claim 12:
13. 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;
creating, by the processor, a first edge map using information from the first set of images, and creating, by the processor, a second edge map using information from the second set of images;
localizing, by the processor, the first joint in the first set of images based on the first edge map, and localizing, by the processor, the second joint in the second set of images based on the second edge map;
matching, by the processor, specific locations of the first joint in the first set of images to corresponding specific locations of the second joint in the second set of images;
comparing, by the processor, temperatures at the specific locations in the first joint to temperatures at the 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.
