图像融合算法
针对电气设备同一场景的红外与可见光图像间一致特征难以提取和匹配的问题,提出了一种基于斜率一致性的配准方法。首先通过数学形态学方法分别提取红外与可见光图像的边缘,得到粗边缘图像;然后通过SURF算法提取两幅边缘图像的特征点,根据正确的匹配点对之间斜率一致性的先验知识,进行特征点匹配;最后通过最小二乘法求得仿射变换模型参数并实现两幅图像的配准。实验结果表明,该方法有效提高了匹配点对的正确率,能够对电气设备红外和可见光图像实现高精度的配准。(In this paper, a method based on slope consistency is proposed to solve the problem that the uniform features of infrared and visible images are difficult to extract and match. Firstly, the edges of infrared and visible images were extracted by mathematical morphology, and the rough edge images were obtained. Then, the feature points of two edge images were extracted by SURF algorithm, and the priori knowledge of slope consistency was obtained according to the correct matching point, and the feature points were matched. Finally, the model parameters of affine transformation are obtained by least square method and the registration of two images is realized. The experimental results show that this method can effectively improve the accuracy of matching points, and can realize high precision registration of infrared and visible images of electrical equipment.)

BM3D
说明: 自己实现的BM3D图像去噪算法。它首先把图像分成一定大小的块,根据图像块之间的相似性,把具有相似结构的二维图像块组合在一起形成三维数组,然后用联合滤波的方法对这些三维数组进行处理,最后,通过逆变换,把处理后的结果返回到原图像中,从而得到去噪后的图像。(Image Denosing by Sparse 3-D Transform-Domain Collaborative Filtering.)
