Research on Two Infrared Point Target Image Preprocessing Techniques Based on Difference
两种基于差分的红外点目标图像预处理技术的研究

The technique of image denoising is one essential part of image processing.Now,a series of relatively mature filter preprocessing techniques have been used in point target detection.In this paper,the preprocessing methods for infrared point target images are analyzed and then two algorithms for background suppression based on difference are given.Finally,these two methods for background suppression are analyzed and compared with each other according to the simulation result.
