Abstract
With the advancement of THz technologies, THz imaging has been progressed significantly and has huge potential applications in medical diagnosis, environmental control, remote sensing, chemical and biological identification. In the past, people mainly focused on overcoming the obstacles in the hardware, such as the limitation of resolution, accuracy and speed in THz imaging system. Improvement of imaging quality is of great significance to the application of terahertz imaging system. In this paper, image enhancement which based on quantum probability statistics is employed to enhance the contrast and get the better profile of THz image. The experimental results are analyzed and discussed. It is shown that our method considered both global and local image information and can improve images quality effectively. The method can effectively suppress the image noise while preserved the object structures well.
