	)

Stretch the contrast of a grayscale image.

Parameters

I1	: The first input grayscale image.
I2	: The second output grayscale image.

stretchContrast() [4/4]

VISP_EXPORT void VISP_NAMESPACE_NAME::stretchContrast

(

VISP_NAMESPACE_ADDRESSING vpImage< VISP_NAMESPACE_ADDRESSING vpRGBa > &

I

)

Stretch the contrast of a color image.

Parameters

I	: The color image to stretch the contrast.

stretchContrastHSV() [1/2]

VISP_EXPORT void VISP_NAMESPACE_NAME::stretchContrastHSV	(	const VISP_NAMESPACE_ADDRESSING vpImage< VISP_NAMESPACE_ADDRESSING vpRGBa > &	I1,
		VISP_NAMESPACE_ADDRESSING vpImage< VISP_NAMESPACE_ADDRESSING vpRGBa > &	I2
	)

Stretch the contrast of a color image in the HSV color space. The saturation and value components are stretch so the hue is preserved.

Parameters

I1	: The first input color image.
I2	: The second output color image.

stretchContrastHSV() [2/2]

VISP_EXPORT void VISP_NAMESPACE_NAME::stretchContrastHSV

(

VISP_NAMESPACE_ADDRESSING vpImage< VISP_NAMESPACE_ADDRESSING vpRGBa > &

I

)

Stretch the contrast of a color image in the HSV color space. The saturation and value components are stretch so the hue is preserved.

Parameters

I	: The color image to stretch the contrast in the HSV color space.

Examples
