The Applications of Feature-Based Image Metamorphosis and Eyelashes Removal in the Investigations of Ocular Thermographic Sequences
Ocular surface temperature relates deeply with ocular physiology. It is nowadays looked into mainly by the use of infrared thermography, and occasionally functional infrared imaging. In this study, we recorded ocular thermographic sequences of 60 normal subjects; 30 of them were young and the rest were the elderly. Ocular region in the thermographic sequences was warped to a standardized form, and the eyelashes in each thermographic image were identified and avoided for further analysis. Average horizontal, vertical temperature profiles were unambiguously defined in the warped thermographic sequences. They were extracted, and comparisons were made between the young and the elderly. It was found that the elder subjects exhibited a cooler temperature profile, but their temperature differences between corneal center and limbus were generally higher.
