Detailed Description

BowTie correction for multi-line instruments.

Function Documentation

correctGenericBowTie()

Image satdump::image::bowtie::correctGenericBowTie	(	Image &	inputImage,
		const int	channelCount,
		const long	scanHeight,
		const float	alpha,
		const float	beta,
		std::vector< std::vector< int > > *	reverse_lut = nullptr )

Performs instrument bowtie correction, required for instruments such as MERSI, MODIS and such.

Parameters

inputImage	the input image
channelCount	number of channels in the image (inputImage.channels())
scanHeight	the height of each scanline group
alpha	value, representing the slant increase of the correction
beta	value, being the offset of the correction
reverse_lut	optionally, generates a LUT to get back the original image pixel positions (eg, for calibration)

Returns

the corrected image
