Member Function Documentation

Apply() [1/2]

Double Murl::Util::GaussianFilter::Apply ( Double  dValH ) const

inlineoverridevirtual

Apply the filter horizontally.

Parameters

dValH

The horizontal distance in range [-filterWidth .. filterWidth].

Returns

e^((-dValH^2) / (2 * sigma^2)) / (sqrt(2 * Pi) * sigma) or zero if distance is out of range.

Implements Murl::IFilter.

Apply() [2/2]

Double Murl::Util::GaussianFilter::Apply ( Double  dValH, Double  dValV  ) const

inlineoverridevirtual

Apply the filter horizontally and vertically.

Parameters

dValH	The horizontal distance in range [-filterWidth .. filterWidth].
dValV	The vertical distance in range [-filterWidth .. filterWidth].

Returns

e^((-dValH^2 + dValV^2) / (2 * sigma^2)) / (2 * Pi * sigma^2) or zero if distance is out of range.

Implements Murl::IFilter.
