Member Function Documentation

void w2qcref::LocalStatistics::compute	(	const code::PolarGrid &	value,
		const code::Length &	targetGateWidth,
		int	targetNumGates
	)			[virtual]

compute, and store, statistics from this polar grid.

Reimplemented from w2qcref::BasicStatistics.

Reimplemented in w2qcref::BlobTextureStatistics.

void w2qcref::LocalStatistics::fillNNInput

(

std::vector< code::Image< float > > *

params

)

[virtual]

copy the stored statistics into the passed-in vector.

Reimplemented from w2qcref::BasicStatistics.

Reimplemented in w2qcref::BlobTextureStatistics.

int w2qcref::Statistics::getElevation

(

)

const [inline, inherited]

static int w2qcref::Statistics::getGateIncrement	(	const code::Length &	inGateWidth,
		const code::Length &	targetGateWidth
	)			[static, inherited]

Number of gates we have to skip to get the targetGateWidth.

For example, if the input grid has a resolution of 0.25km, but the target is 1km, the gate increment is 4.
