[OpenCV] Samples 10: imagelist_creator

yaml写法的简单例子。将 $ ./ 1 2 3 4 5 命令的参数（代表图片地址）写入yaml中。

 

写yaml文件。

参考：[OpenCV] Samples 06: [ML] logistic regression 读xml文件。

         * Jeff --> Load xml.
         *          transform to Mat.
         * FileStorage.

        cout << "loading the dataset...";
        // Step 1.
        FileStorage f;
        if(f.open(filename, FileStorage::READ))
        {
            // Step 2.
            f["datamat"] >> data;
            f["labelsmat"] >> labels;
            f.release();
        }
        else
        {
            cerr << "file can not be opened: " << filename << endl;
            return 1;
        }
        // Step 3.
        data.convertTo(data, CV_32F);
        labels.convertTo(labels, CV_32F);
 
        cout << "read " << data.rows << " rows of data" << endl;
    }
