Function Documentation

◆ stretchContrast() [1/4]

void vp::stretchContrast ( const vpImage< unsigned char > &  I1,
vpImage< unsigned char > &  I2 
)

Stretch the contrast of a grayscale image.

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

Definition at line 446 of file vpImgproc.cpp.

◆ stretchContrast() [2/4]

void vp::stretchContrast ( const vpImage< vpRGBa > &  I1,
vpImage< vpRGBa > &  I2 
)

Stretch the contrast of a color image.

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

Definition at line 539 of file vpImgproc.cpp.

◆ stretchContrast() [3/4]

void vp::stretchContrast ( vpImage< unsigned char > &  I)

Stretch the contrast of a grayscale image.

Parameters
I: The grayscale image to stretch the contrast.
Examples
testImgproc.cpp, and tutorial-contrast-sharpening.cpp.

Definition at line 417 of file vpImgproc.cpp.

◆ stretchContrast() [4/4]

void vp::stretchContrast ( vpImage< vpRGBa > &  I)

Stretch the contrast of a color image.

Parameters
I: The color image to stretch the contrast.

Definition at line 460 of file vpImgproc.cpp.

◆ stretchContrastHSV() [1/2]

void vp::stretchContrastHSV ( const vpImage< vpRGBa > &  I1,
vpImage< 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.

Definition at line 607 of file vpImgproc.cpp.

◆ stretchContrastHSV() [2/2]

void vp::stretchContrastHSV ( vpImage< 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 stetch the contrast in the HSV color space.
Examples
testImgproc.cpp, and tutorial-contrast-sharpening.cpp.
