c++中Mat型的一些问题

 CV_8U - 8-bit unsigned integers 

• CV_8S - 8-bit signed integers

• CV_16U - 16-bit unsigned integers

• CV_16S - 16-bit signed integers 

• CV_32S - 32-bit signed integers

• CV_32F - 32-bit floating-point numbers

• CV_64F - 64-bit floating-point numbers 

使用convertTo在格式之间转换，如下所示：

srcImg.convertTo(dstImg, CV_32F);
