The Research Of Infrared Image Preprocessing And Small Target Detection Under Complex Background

In recent years, with the quick development of computer and digital image processing technology, the infrared image technique start to be extensive apply in many fields like making to lead, follow, automatic control, artificial intelligence etc. As the infrared target has the characteristics that the distance is far, the area is small, the shape characteristic is weak, the detail characteristic is part lose and the SNR is low etc., it is much more important and difficult to do the job of infrared image preprocessing and detection. How to take full advantage of the infrared image preprocessing and target detection techniques to increase the distance of target detection is an important factor in the field of infrared lead.We discuss about the problem of infrared small target processing in complex background at three aspects. Firstly, we present the part of preprocessing of infrared image. As it is usual that there exists noise in the original image, how to make full use of the characteristic of infrared imaging, remove the noise from the image itself and other factors...
