Functions
void	satdump::image::white_balance (Image &img, float percentileValue=0.05f)
	While balance algorithm from Gimp.
void	satdump::image::median_blur (Image &img)
	Median blur. Somewhat equivalent to Gimp's with a radius of 1.
void	satdump::image::kuwahara_filter (Image &img)
	Adaptive noise reduction filter.
void	satdump::image::equalize (Image &img, bool per_channel=false)
	Perform histogram equalization.
void	satdump::image::normalize (Image &img)
	Normalize the current image data. This takes the current min and max values and extends it to the full bit depth range.
void	satdump::image::linear_invert (Image &img)
	Invert the entire image. Blacks becomes white and the opposite.
void	satdump::image::simple_despeckle (Image &img, int thresold=10)
	Despeckle the image. Very basic despeckle algorithm.

Detailed Description

Various processing functions (blur, equalize...)

Function Documentation

equalize()

void satdump::image::equalize	(	Image &	img,
		bool	per_channel = false )

Perform histogram equalization.

Parameters

img	image to equalize
per_channel	if true, performs the equalization separately for each spectral channel

kuwahara_filter()

void satdump::image::kuwahara_filter

(

Image &

img

)

Adaptive noise reduction filter.

Parameters

img	image to process

linear_invert()

void satdump::image::linear_invert

(

Image &

img

)

Invert the entire image. Blacks becomes white and the opposite.

Parameters

img	image to process

median_blur()

void satdump::image::median_blur

(

Image &

img

)

Median blur. Somewhat equivalent to Gimp's with a radius of 1.

Parameters

img	image to blur

normalize()

void satdump::image::normalize

(

Image &

img

)

Normalize the current image data. This takes the current min and max values and extends it to the full bit depth range.

Parameters

img	image to process

simple_despeckle()

void satdump::image::simple_despeckle	(	Image &	img,
		int	thresold = 10 )

Despeckle the image. Very basic despeckle algorithm.

Parameters

img	image to process
thresold	difference over which the pixel is considered bad

white_balance()

void satdump::image::white_balance	(	Image &	img,
		float	percentileValue = 0.05f )

While balance algorithm from Gimp.

Parameters

img	image to white balance
percentileValue	percentile to balance to
