image_classification's Introduction

关于工程

本工程使用LibSVM对风景与建筑图片进行分类。很早之前做的了，突然找到，原为本科图像处理课的作业，整理之后放在这里。.docx包括了SVM的原理，参数优化方法。

Code File Discription

  1. main.m 主调用模块
  2. cross_validation.m 交叉验证
  3. eval_func.m 评估函数
  4. eval_predict.m 使用自定义的评估函数进行SVM预测
  5. extractfeature.m 特征提取
  6. svm_girdsearch.m 格点搜索
  7. ./libsvm-3.17 libsvm matlab格式工具包，已在32bit机上编译，在64位机上进入libsvm-3.17/matlab目录使用make重新编译
  8. data.mat 已提取特征后的保存数据，减少每次都从头读取图片的麻烦

NOTES:原始数据文件默认存放在images目录下，包括manmade和nature文件夹
