Paper Abstract

In this paper, taking the Digital Infrared Thermal Imager as the object of study, infrared thermal image and its noise types and characteristics are researched into in detail, and the image noise theoretical model is described unitedly by the time and space domain stochastic process. On the basis of these, Infrared Thermal Image Processing System is set up. New types of time and space domain image processing theory and technique-interframe comparison denoise process and adaptive mode filter are put forward and taken to suppress infrared thermal image noise. Theoretical and experimental results show that interframe comparison denoise process and adaptive mode filter suppress infrared thermal image noise more effectively than image frame-accumulation method and mode filter. At last, Infrared Thermal Imager Signal and Noise Test and Analysis System is developed specially, and the test and analysis evaluation on the original and processed images are carried out.
