Study on Hyperthyroidism using Thermal Image Analysis

Hyperthyroidism is supposed to impact three major areas of the body: the eye, the neck, and the shin. The participants are examined, with a thermal camera, potentially non-invasive, less expensive technique to measure the level of temperature distributed in the eyes, neck, and shin region due to hyperthyroidism. The temperature distribution is seen through the color map of the images which indicates the minimum and maximum temperatures. The heat distribution in the eye, neck and shin region is studied and a qualitative and quantitative analysis is performed. The pre-processing techniques include cropping of the acquired image using the required threshold values. Then the cropped image are normalized and masked in the eyeball region, left and right eye respectively .The surface plot of the preprocessed image is obtained for visualization of the intensity distribution. The sum of extrema (SX) is computed from the masked image. On the other hand the gradient operator is applied to the normalized image and fractal dimensions (FD) are computed using Higuchi algorithm .The intensity levels are analyzed in the red, green and blue regions respectively. The temperature distribution pattern of the hyperthyroid participant and normal participants are determined using the FD and SX. The statistical analysis is also performed to study the complexities in each of the regions for healthy and hyperthyroid participants.
