| 摘 要： | 由于红外图像具有高噪声、低分辨率的特点,这使得在红外图像中使用基于区域的匹配方法很难取得较好的视差图.在分析了经相位一致性变换后图像的特征后,提出了一种基于区域的匹配方法.即先对图像进行相位一致性变换,再利用变换后图像进行区域匹配.试验结果表明,相位一致性变换后的新图像,噪声得到了较好的抑制,特征更加明显.对变换后的图像采用区域匹配的方法,可以得到较好的匹配效果.

| Abstract: | Infrared images have higher noise and lower resolution than visible images.This makes it more difficult to achieve a better disparity image in infrared images by using the method based on region matching.After analyzing the phase congruency transformed image,a new region matching method was presented.First,the images were transformed by phase congruency.Next,the images were matched based on region correlation.The experimental result indicates that the noise of images is restrained and the feature is more di... |
