| 摘 要： | 针对红外图像边缘检测这一难题,提出了一种基于红外图像差值图的模糊边缘检测方法。首先通过计算图中每个像素点与其邻域8像素点灰度值的差值,然后寻找这些差值的最大值得到图像的差值图,接着对差值图像的边缘区域和平滑区域进行模糊划分,利用差值直方图模型确定红外图像差值图的分割阈值,从而实现边缘提取。实验结果表明,该方法用于红外图像边缘检测能获得较好的效果。

| Abstract: | Considering the difficulty on the edge detection of infrared image, a fuzzy edge detection based on infrared image difference chart is introduced.Firstly,the difference chart is constructed by computing the difference value between the pixel and the surround 8 pixels;Secondly,implements fuzzy partition to infrared difference image,gets the edge region and smooth region,and achieves the segmentation value by use of the difference histogram;lastly,the experiment is conducted on various infrared images and the results show that the proposed approach has better performance than some classical edge detection methods based on gradient. |
