Member Function Documentation

bool w2img::ImageComparator::findError	(	double	orig,
		double	filtered,
		double &	error,
		bool &	origValid,
		bool &	estValid
	)			const [inherited]

Find the error.

The error is (filtered - orig) if both numbers are valid.

Returns:

true if the error returned is a usable number The error will be flagged as Constants::MissingData if both orig and filtered are invalid unless includeNulls was set in the constructor. Definition: An invalid value is a value equal to Constants::MISSING_DATA or less than minValue (if maxIsBetter).

std::vector<Score> w2img::ImageComparator::score	(	const code::Image< float > &	orig,
		const code::Image< float > &	fil
	)			const [inherited]

std::vector<Score> w2img::ImageComparator::score	(	const code::PolarGrid &	orig,
		const code::PolarGrid &	fil
	)			const [inherited]

the two images should be of identical sizes.

std::vector<Score> w2img::ImageComparator::score	(	const code::LatLonGrid &	orig,
		const code::LatLonGrid &	fil
	)			const [inherited]

the two images should be of identical sizes.

std::vector<Score> w2img::ImageComparator::score	(	const code::CartesianGrid2D &	orig,
		const code::CartesianGrid2D &	fil
	)			const [inherited]

the two images should be of identical sizes.

the return is the Score for each of the given kernels.

virtual Score w2img::ProbabilisticImageComparator::scoreFiltered	(	const code::Image< float > &	orig,
		const code::Image< float > &	fil_prob
	)			const [virtual]

uses a fake image based on the probability encoded in fil_prob and calls ImageComparator::scoreFiltered

Reimplemented from w2img::ImageComparator.

void w2img::ImageComparator::updateScore	(	double	orig,
		double	filtered,
		ImageComparator::Score *	score
	)			const [inherited]

Updates this score based on the orig and filtered values if findError returns true.
