Abstract: Infrared thermography is an alternate to the thermometer to measure body temperature. Infrared (IR) camera can map the body temperature into intractable images. This paper provides a survey on the contribution of thermal images to analyze the breast cancer. The features are extracted from the mapped thermogram images for further image processing. This survey mainly concentrates on the comparison of statistical and texture features of normal and abnormal IR breast images, various types of segmentation and Region Of Interest (ROI) extraction, modern IR camera specifications and various classification techniques to early detect the abnormality in the breast using thermal images obtained from the database.
