Description: 指南针边缘检测算法是当前质量最高的边缘检测方法，比CANNY算子效果还要好。具有边缘定位准确，边连续，完整的特点。程序能够得到每一个像素的边的朝向，有利于做进一步的优化应用，例如图像分割等。具体算法过程可参考斯坦福大学麦克博士发表的论文。主要思路就是以每个像素为中心，像罗盘一样转动边，一直找到两边差异最大的朝向。最后把所有的最优朝向连起来成为边缘。
代码用VC驱动，核心部分用matlab编写-Compass edge detection algorithm is currently the highest quality of edge detection methods, than CANNY operator even better results. With edge positioning accuracy, while continuous, full features. Program can be a pixel for each side towards is beneficial for further optimization of applications, such as image segmentation and so on. Specific algorithms may make reference to Stanford University Maikeboshi the published papers. Main idea is to each pixel as the center, the same rotation as the compass edge, has been to find the greatest difference between both sides of the orientation of. Finally all the best to link into the edge towards. Code using VC-driven, the core part of the preparation with matlab Platform: |

Description: 本程序集合了互信息配准，PV差值，powell算法，基于小波变换的图像融合的一整套算法。只需要在GUI界面输入两幅图像，即可自动完成图像的配准融合。程序包含Matlab源代码。用Matlab打开imagefusion.m，即会弹出gui界面。融合前要输入参考和浮动图像。图像要求像素的 长＊宽 一样。否则会报错。程序只能处理灰度图像，彩色图像也会转化成灰度图像处理。程序代码已经有详细的注释，方便读者理解。-The procedures set of mutual information, PV difference, powell algorithm, based on wavelet transform image fusion set of algorithms. Only need to enter the two images in the GUI interface, you can automatically complete the image registration fusion. Program contains Matlab source code. Using Matlab open imagefusion.m, gui interface will pop up. Fusion before the input reference and floating images. Image requires the same pixel length* width. Otherwise incorrect. Can only handle grayscale images, color images into gray image processing also. Program code has detailed notes, to facilitate understanding. Platform: |
