Description: AffineTransformation computes and applies the geometric affine transformation to a 2-D image.
The program main functions are:
- Load Image: Load the image to be transformed.
- Transform Image: Computes the transformation matrix from the transformation parameters specified by the user, then it applies the transformation to the loaded image.
- Save Image: Save the transformed image.
- Quit: Exit the program.
The transformation parameters are specified by the user by editing the
values of the rotation, scale (x and y), and shear (x and y). The
translation is not icluded because it can be easily (normalized or) removed from the image by
subtracting the shape cetroid.
The affine matrix and the affinr transformation are computed using Matlab Image Processing Toolbox
functions: maketform and imtransform. So this program is only demonstrates and facilitates the computation and the applying of these functions to a 2-D image.

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: |
