opencv Basic Structures DataType
Example
The primitive types in OpenCV are unsigned char, bool, signed char, unsigned short, signed short, int, float, double.
Any data type in OpenCV is defined as CV_<bit-depth>{U|S|F}C(<number_of_channels>) where U: unsigned, S:signed and F:floating point.
For example, CV_32FC2 is a 32-bit, floating-point, and 2-channels structure. and the definition of basic, one channel types are
#define CV_8U 0
#define CV_8S 1
#define CV_16U 2
#define CV_16S 3
#define CV_32S 4
#define CV_32F 5
#define CV_64F 6
#define CV_USRTYPE1 7
The other types with higher channel are produced from these by the following definition:
#define CV_MAKETYPE(depth,cn) (CV_MAT_DEPTH(depth) + (((cn)-1) << CV_CN_SHIFT))
Using these datatypes other structures can be created.
