构造函数

Mat()

Mat(int rows,int cols,int type)

Mat(Size size,int type)

Mat(int rows,int cols,int type,const Scalar &s)

Mat(Size size,int type,const Scalar &s)

Mat(int ndims,const int *sizes,int type)

Mat(int ndims,const int *sizes,int type,const Scalar &s)

 

常用方法：

void copyTo(Mat outputImg)

void convertTo(Mat dst,int type)

Mat clone()

int channels()

int depth()

bool empty()

uchar* ptr(i=0)
