| 摘 要： | 针对可见光和红外图像的配准问题,提出了一种改进的基于感兴趣区域梯度互信息的多模图像配准方法。该算法从两个方面做了改进,首先,为了提高算法性能,对图像做了预处理抑制噪声,然后通过对图像进行灰度级降采样操作,合理选择较少的灰度级达到减少计算量的目的;其次,提取图像中复杂度高的区域作为感兴趣区域来代替整幅图像进行配准,这样不...

| Abstract: | Mutual information(MI) based method has been widely used for solving multi-mode image registration problem.This paper presents an improved multi-mode image registration method based on MI of region of interests(ROIs).Improvements are made from the following two aspects.Firstly,in order to increase the performance of this algorithm,image preprocessing is applied to suppress the effect of noises,and image grey levels down sampling by means of rescaling intensity levels properly is operated to reduce calculati... |
