Opencv版本更迭过程中遇到的“坑”

/*2.4.10版本*/
normalize(m_V_vector, m_V_vector, 1, 0, NORM_MINMAX, CV_32FC1);//normalize 内部可以自动实现数据类型转换
normalize(m_V_vector, m_V_vector, 255, 0, NORM_MINMAX, CV_32FC1);
m_V_vector.convertTo(m_V_vector, CV_8UC1);
imshow("m_V_vector", m_V_vector);
cvWaitKey(0);

/*3.1.0版本*/
//OPENCV 3.1.0 库内限制性更高，输入和输出一致； 2.4.10内部有
m_V_vector.convertTo(m_V_vector, CV_32FC1);//输入数据提前转换好
normalize(m_V_vector, m_V_vector, 1, 0, NORM_MINMAX);//normalize 内部无法实现自动数据类型转换
normalize(m_V_vector, m_V_vector, 0, 255, NORM_MINMAX);
m_V_vector.convertTo(m_V_vector, CV_8UC1);
imshow("m_V_vector", m_V_vector);
cvWaitKey(0);
