Inheritance diagram for vetVision:

Public Types
enum
	Ignore this, it's a class-type definition, mostly used by VETLib WorkShop, sintax is a bit more complex than usual because of a VC6 BUG, it's the same as: const int vetClassType = VETCLASS_TYPE_OBJECT;.
Public Member Functions
	vetVision ()
	Default constructor call vetInput constructor which setup frame rate, initialize description arrays and set default name (should be updated).
virtual	~vetVision ()
	Destructor currenly clear only filters description strings.
void	setAlertCall (void *(*functionCall)(void *))
void	setAlertCallArgument (void *arg)
void *	getAlertCallArgument ()
virtual VETRESULT	reset ()=0
	Inherited class must implement this function, should reset all filters' parameters, something like constructor initialization.
virtual VETRESULT	importFrom (vetFrameYUV420 &img)=0
	Inherited class must implement this function, processing frames to specific output (device or stream).
virtual VETRESULT	importFrom (vetFrameRGB24 &img)=0
	Inherited class must implement this function, processing frames to specific output (device or stream).
virtual VETRESULT	importFrom (vetFrameT< unsigned int > &img)=0
	Inherited class must implement this function, processing frames to specific output (device or stream).

Constructor & Destructor Documentation

vetVision::vetVision (   )

Default constructor call vetInput constructor which setup frame rate, initialize description arrays and set default name (should be updated). Parameters: fps  Frame per second value, default is 0, the max input+processing rate. Definition at line 27 of file vetVision.cpp. References alertCallArgument, vetObject::setDescription(), vetObject::setName(), and vetObject::setVersion().

Member Function Documentation

virtual VETRESULT vetVision::importFrom (  vetFrameT< unsigned int > &  img  )  [pure virtual]

Inherited class must implement this function, processing frames to specific output (device or stream). Parameters: [in]  img  Greyscale VETLib Frame to be processed (encoded for example) Returns: VETRET_OK if everything is fine, VETRET_PARAM_ERR if frame is not valid, VETRET_INTERNAL_ERR or VETRET_ILLEGAL_USE else. Note: Input operator (<<) call directly this function. See also: operator << (vetFrameT&)

virtual VETRESULT vetVision::importFrom (  vetFrameRGB24 &  img  )  [pure virtual]

Inherited class must implement this function, processing frames to specific output (device or stream). Parameters: [in]  img  VETLib Cache24 Frame to be processed (encoded for example) Returns: VETRET_OK if everything is fine, VETRET_PARAM_ERR if frame is not valid, VETRET_INTERNAL_ERR or VETRET_ILLEGAL_USE else. Note: Input operator (<<) call directly this function. See also: operator << (vetFrameRGB24&) Implements vetOutput. Implemented in vetMotionIlluminationInvariant, and vetMotionLame.

virtual VETRESULT vetVision::importFrom (  vetFrameYUV420 &  img  )  [pure virtual]

Inherited class must implement this function, processing frames to specific output (device or stream). Parameters: [in]  img  VETLib Cache Frame to be processed (encoded for example) Returns: VETRET_OK if everything is fine, VETRET_PARAM_ERR if frame is not valid, VETRET_INTERNAL_ERR or VETRET_ILLEGAL_USE else. Note: Input operator (<<) call directly this function. See also: operator << (vetFrameYUV420&) Implements vetOutput. Implemented in vetMotionIlluminationInvariant, and vetMotionLame.

virtual VETRESULT vetVision::reset (   )  [pure virtual]

Inherited class must implement this function, should reset all filters' parameters, something like constructor initialization. Returns: VETRET_OK if everything is fine, VETRET_INTERNAL_ERR or VETRET_ILLEGAL_USE else. Implemented in vetMotionIlluminationInvariant, and vetMotionLame.
