基于相位保持的红外图像预处理方法
Phase Preserving Based Infrared Image Preprocessing Method
摘要
Abstract
Noises and non-uniformity may severely affect the infrared image quality, and limits the application of infrared images. Therefore, a simple and effective infrared image preprocessing method is proposed. By combing high -pass filtering with the phase preserving image denoising algorithm, we intend to realize non-uniformity correction (NUC) during the procedure of denoising, thus to obtain clearer infrared image. Experimental results show that with this method, we could effectively depress non-uniformity of intensity and increase the peak signal and noise ratio (PSNR). It could improve the quality of infrared image visually and quantitatively.关键词
