在函数cvCreatMTStumpClassifier中遇到了CV_IS_ROW_SAMPLE,网上查了下资料,很少,现在我总结如下,希望能帮助大家理解。如大家对cvCreatMTStumpClassifier不理解的,请参考我博客中的文章http://blog.csdn.net/ding977921830/article/details/46356789和http://blog.csdn.net/ding977921830/article/details/46412465。
// 函数功能:计算最优弱分类器 CvClassifier* cvCreateMTStumpClassifier( CvMat* trainData, // 训练样本HAAR特征值矩阵 int flags, // 1.按行排列,0.按列排列 CvMat* trainClasses, CvMat* /*typeMask*/, CvMat* missedMeasurementsMask, CvMat* compIdx, CvMat* sampleIdx, CvMat* weights, CvClassifierTrainParams* trainParams ) { ....... }
/* columns of <trainData> matrix are training samples */ //矩阵traindata的列是训练样本,对应上述的flags=0 #define CV_COL_SAMPLE 0 /* rows of <trainData> matrix are training samples */ //矩阵traindata的行是训练样本,对应上述的flags=1 #define CV_ROW_SAMPLE 1 #define CV_IS_ROW_SAMPLE(flags) ((flags) & CV_ROW_SAMPLE)
宏CV_IS_ROW_SAMPLE(flags)是带有参数的宏,当flags=0时,宏CV_IS_ROW_SAMPLE的含义是0,当flags=1时,宏CV_IS_ROW_SAMPLE的含义是1.
可以看出在opencv的开源库中,c++的编程是非常灵活的,而且内容是具有一定含义和代表性的。
