一种基于图像融合的红外图像预处理算法
A Method for Infrared Images Pre-processing based on Image Fusion
摘要
Abstract
In the traditional filtering method to preprocess the image, the edges of target and background are usually blurred while the noise information being weakened, which is not conducive to the further processing of the image information. Aiming at this problem, this paper proposes image preprocessing techniques based on image fusion:firstly applying improved median filtering algorithm and improved Sobel edge extraction algorithm respectively on the same degraded infrared image, then using the pixel level image fusion algorithm to combine the two processing results. The final fusion results show a clear image with significantly enhanced edge portion with a simple operation. In a word, this preprocessing method is conducive to the target detection and recognition in following treatment and achieves the image preprocessing requirements.关键词
