This document discusses using thermal infrared imaging to identify malignant regions in the human body. It begins with an overview of cancer and different imaging techniques used for detection like X-ray, MRI, and optical imaging. The advantages of thermal imaging are discussed, including its ability to detect differences in surface temperature that could indicate abnormal cell growth. The document then focuses on thermal imaging in more detail, outlining the process of preprocessing, feature extraction, and analyzing thermal images to identify potential malignant regions based on changes in temperature. It concludes that thermal infrared imaging shows potential for non-invasive cancer detection but requires further clinical studies to develop standardized protocols.
