基于susan算法的边缘提取

代码说明:

susan.m实现运用susan算子进行边缘检测;susan_threshold.m的功能是设定susan算法的阀值。阀值threshold表示所能检测边缘点的最小对比度,也是能忽略的噪声的最大容限。t越小,可以从对比度越低的图像中提取特征。因此对不同对比度和噪声情况的图像,应取不同的t值。

  • svm_new
    MATLAB的SVM算法实现,Matlab Support Vector Machine Toolbox,This toolbox was designed as a teaching aid, which matlab is particularly good for since source code is relatively legible and simple to modify. However, it is still reasonably fast if used with the supplied optimiser. However, if you really want to speed things up you should consider compiling the matrix composition routine for H into a mex function. Then again if you really want to speed things up you probably shouldn t be using matlab anyway... Get hold of a dedicated C program once you understand the algorithm.(MATLAB-SVM algorithm, Matlab Support Vector Machine Toolbox, This toolbox was designed as a teaching aid, which matlab isparticularly good for since source code is relatively legible andsimple to modify.
