Detailed Description

Function Documentation

EqualizeHistogram()

void oevislib_net.Image.EqualizeHistogram ( Optional< Region > inRoi = null, float inSaturateBrightestFraction = 0::0f, float inSaturateDarkestFraction = 0::0f )

inline

Update the image's pixels to new values to achieve a uniform distribution of intensities in the range (0, 255).

The image must have UInt8 pixel type and a single channel.

Parameters

inRoi	Region of interest.
inSaturateBrightestFraction	Fraction of brightest pixels skipped during normalization. Range: [0, 1].
inSaturateDarkestFraction	Fraction of darkest pixels skipped during normalization. Range: [0, 1].

Normalize()

void oevislib_net.Image.Normalize ( Optional< Region > inRoi = null, float inNewMinimum = 0::0f, float inNewMaximum = 255::0f, float inSaturateBrightestFraction = 0::0f, float inSaturateDarkestFraction = 0::0f, float inMinValue = 0::0f, float inMaxValue = 255::0f, Optional< float > outA = null, Optional< float > outB = null, Optional< Region > outLinearNormalizedRegion = null )

inline

Normalizes the image (in-place) so that its minimum becomes inNewMinimum and the maximum becomes inNewMaximum.

Parameters

inRoi	Region of interest.
inNewMinimum	New minimum value.
inNewMaximum	New maximum value.
inSaturateBrightestFraction	Fraction of brightest pixels skipped during normalization. Range: [0, 1].
inSaturateDarkestFraction	Fraction of darkest pixels skipped during normalization. Range: [0, 1].
inMinValue	Value under which pixels will not be considered.
inMaxValue	Value above which pixels will not be considered.
outA	Multiplicative parameter obtained by the linear transformation.
outB	Additive parameter obtained by the linear transformation.
outLinearNormalizedRegion	Region of pixels that have been normalized.

NormalizeLocalContrast()

void oevislib_net.Image.NormalizeLocalContrast ( Optional< Region > inRoi = null, float inTargetMean = 128::0f, float inTargetVariance = 50::0f, int inUniformnessRadius = 1, float inBrightnessPreserveRatio = 0::0f )

inline

Normalizes the local contrast of the image.

Enhances the contrast of small regions in the image while leaving the overall contrast unchanged. This can be useful for improving the visibility of details in an image, such as the edges of objects or the texture of surfaces.

Parameters

inRoi	Region of interest.
inTargetMean	Target local mean.
inTargetVariance	Target local variance. Range: [0.1, +inf).
inUniformnessRadius	Radius of the neighborhood to uniformize. Range: [1, +inf).
inBrightnessPreserveRatio	How much of the original brightness to keep. Range: [0, 1].

Sharpen()

void oevislib_net.Image.Sharpen ( KernelShape inKernel = KernelShape::Box, int inRadiusX = 1, Optional< int > inRadiusY = null, float inContrastFactor = 1::0f )

inline

Enhances the contrast of the image to make it look sharper.

Parameters

inKernel	Kernel shape.
inRadiusX	Kernel's width. Range: [0, +inf).
inRadiusY	Kernel's height (equal to inRadiusX if not specified). Range: [0, +inf).
inContrastFactor	Strength of the contrast enhancement. Range: [0, +inf).
