Detailed Description

Gamma correction.

Function Documentation

◆ gammaCorrection() [1/4]

VISP_EXPORT void VISP_NAMESPACE_NAME::gammaCorrection ( const VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &  I1,
VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &  I2,
const float &  gamma,
const vpGammaMethod method = GAMMA_MANUAL,
const VISP_NAMESPACE_ADDRESSING vpImage< bool > *  p_mask = nullptr 
)

Perform a gamma correction on a grayscale image.

Parameters
[in]I1: The first grayscale image.
[out]I2: The second grayscale image after gamma correction.
[in]gamma: Gamma value. If equals to -1, use automatic Gamma correction based on a non-linear technique. If equals to -2, use automatic Gamma correction based on a logarithmic technique. If equals to -3, uses automatic Gamma correction based on classification. If equals to -4, uses automatic Gamma correction based on probabilistic.
[in]method: The method to use: either GAMMA_MANUAL if the user wants to use a positive constant gamma factor, or one of the automatic method if gamma is negative.
[in]p_mask: If different from nullptr, permits to indicate which points must be taken into account by setting them to true.

◆ gammaCorrection() [2/4]

VISP_EXPORT void VISP_NAMESPACE_NAME::gammaCorrection ( const VISP_NAMESPACE_ADDRESSING vpImage< VISP_NAMESPACE_ADDRESSING vpRGBa > &  I1,
VISP_NAMESPACE_ADDRESSING vpImage< VISP_NAMESPACE_ADDRESSING vpRGBa > &  I2,
const float &  gamma,
const vpGammaColorHandling colorHandling = GAMMA_RGB,
const vpGammaMethod method = GAMMA_MANUAL,
const VISP_NAMESPACE_ADDRESSING vpImage< bool > *  p_mask = nullptr 
)

Perform a gamma correction on a color image.

Parameters
[in]I1: The first color image.
[out]I2: The second color image after gamma correction.
[in]gamma: Gamma value.
[in]colorHandling: How to handle the colors of the image.
[in]method: The method to use: either GAMMA_MANUAL if the user wants to use a positive constant gamma factor, or one of the automatic method if gamma is negative.
[in]p_mask: If different from nullptr, permits to indicate which points must be taken into account by setting them to true.

◆ gammaCorrection() [3/4]

VISP_EXPORT void VISP_NAMESPACE_NAME::gammaCorrection ( VISP_NAMESPACE_ADDRESSING vpImage< unsigned char > &  I,
const float &  gamma,
const vpGammaMethod method = GAMMA_MANUAL,
const VISP_NAMESPACE_ADDRESSING vpImage< bool > *  p_mask = nullptr 
)

Perform a gamma correction on a grayscale image.

Parameters
[in,out]I: The grayscale image to apply gamma correction.
[in]gamma: Gamma value. If equals to -1, use automatic Gamma correction based on a non-linear technique. If equals to -2, use automatic Gamma correction based on a logarithmic technique. If equals to -3, uses automatic Gamma correction based on classification. If equals to -4, uses automatic Gamma correction based on probabilistic.
[in]method: The method to use: either GAMMA_MANUAL if the user wants to use a positive constant gamma factor, or one of the automatic method if gamma is negative.
[in]p_mask: If different from nullptr, permits to indicate which points must be taken into account by setting them to true.
Examples
testImgproc.cpp, and tutorial-brightness-adjustment.cpp.
