Design and Use of Steerable Filters PAMI1991文章的代码，含有测试图像和demo，可运行-It implements a steerable Gaussian filter. This m-file can be used to evaluate the first directional derivative of an image, using the method outlined in: W. T. Freeman and E. H.

支持向量机SVM可以使用多分类的问题，本次的代码实现的就是这个功能，里面含有训练和测试数据，分别含有12类标签，也就是都分为12类，另外代码采用了神经网络中的one-versus-one的思想，将数据分类K（K-1）/2个子类，分别调用SVM方法实现-It is about the classification in use of SVM for 12 classes. The algorithm contains training data and test data.

此包含有基于TensorFlow平台上的一个分类问题，适合初学者使用。含有实验数据，测试数据，完整代码，优化代码，可视化代码。(This package contains a classification problem based on TensorFlow platform, suitable for beginners to use. Contains experimental data, test data, complete code, optimization code, visua
