virtual bool lti::splitImageToHSV::apply	(	const rgbPixel &	pixel,
		ubyte &	H,
		ubyte &	S,
		ubyte &	V
	)			const [virtual]

split the pixel in hue value H, saturation S and Value V.

The values of each pixel will be between 0 and 255

Parameters:

	pixel	the pixel to be splitted
	H	the hue value
	S	the saturation value
	V	the Value value

Implements lti::splitImage.

virtual bool lti::splitImageToHSV::apply	(	const rgbPixel &	pixel,
		float &	H,
		float &	S,
		float &	V
	)			const [virtual]

split the pixel in hue value H, saturation S and Value V.

The values of each pixel will be between 0.0f and 1.0f

Parameters:

	pixel	the pixel to be splitted
	H	the hue value
	S	the saturation value
	V	the Value value

Implements lti::splitImage.

virtual bool lti::splitImageToHSV::apply	(	const image &	img,
		channel8 &	H,
		channel8 &	S,
		channel8 &	V
	)			const [virtual]

split the image in hue channel H, saturation S and value channel V.

The values of each image will be between 0 and 255

Parameters:

	img	the image to be splitted
	H	the hue channel
	S	the saturation channel
	V	the value channel

Implements lti::splitImage.

virtual bool lti::splitImageToHSV::apply	(	const image &	img,
		channel &	H,
		channel &	S,
		channel &	V
	)			const [virtual]

split the image in hue channel H, saturation S and value channel V.

The values of each image will be between 0.0f and 1.0f

Parameters:

	img	the image to be splitted
	H	the hue channel
	S	the saturation channel
	V	the value channel

Implements lti::splitImage.

virtual functor* lti::splitImageToHSV::clone

(

)

const [virtual]

returns a pointer to a clone of the functor

Implements lti::functor.

virtual bool lti::splitImageToHSV::getThird	(	const image &	img,
		channel8 &	c3
	)			const [virtual]

Returns the third of the three channels into which the image is split.

If you need only one channel, this might be faster than calling apply().

Parameters:

	img	the source image
	c3	the extracted channel

Reimplemented from lti::splitImage.

virtual bool lti::splitImageToHSV::getThird	(	const image &	img,
		channel &	c3
	)			const [virtual]

Returns the third of the three channels into which the image is split.

If you need only one channel, this might be faster than calling apply().

Parameters:

	img	the source image
	c3	the extracted channel

Reimplemented from lti::splitImage.

virtual const char* lti::splitImageToHSV::getTypename

(

)

const [virtual]

returns the name of this type

bool lti::splitImageToHSV::getValue	(	const image &	img,
		channel8 &	value
	)			const

shortcut to get the value channel only The values of each pixel will be between 0 and 255.

Parameters:

	img	the image to be splitted
	value	the value channel

bool lti::splitImageToHSV::getValue	(	const image &	img,
		channel &	value
	)			const

shortcut to get the value channel only The values of each pixel will be between 0.0f and 1.0f.

Parameters:

	img	the image to be splitted
	value	the value channel
