Detailed Description

Type information.

The structure contains information about one of the standard or user-defined types. Instances of the type may or may not contain a pointer to the corresponding CvTypeInfo structure. In any case, there is a way to find the type info structure for a given object using the cvTypeOf function. Alternatively, type info can be found by type name using cvFindType, which is used when an object is read from file storage. The user can register a new type with cvRegisterType that adds the type information structure into the beginning of the type list. Thus, it is possible to create specialized types from generic standard types and override the basic methods.
