Detailed Description

SoGradientMagnitudeProcessing2d engine

For an introduction to gradient operations, see section Introduction to Gradient.

The SoGradientMagnitudeProcessing2d engine computes the gradient amplitude and orientation from gradient images along X and Y axis. The results depend on the selected gradient mode.

See also: SoGradientOperatorProcessing2d, SoGradientMagnitudeProcessing3d.

Member Enumeration Documentation

enum SoGradientMagnitudeProcessing2d::GradientMode

Enumerator:

AMPLITUDE_MAX_OF_MAGS	This option computes the gradient amplitude as the maximum of magnitudes. Only the outAmplitudeImage output is set using this mode.
AMPLITUDE_EUCLIDEAN	This option computes the gradient euclidean amplitude. Only the outAmplitudeImage output is set using this mode.
AMPLITUDE_AND_ORIENTATION	This option computes euclidean amplitude and the orientation (between -128° and +128°). Both outAmplitudeImage and outOrientationImage outputs are set using this mode.
