Header:	AVL.h
Namespace:	avl
Module:	Photometric

Computes the surface curvature using previously computed normals.

Syntax

void avl::PhotometricStereo_SurfaceCurvature
(
	const avl::Image& inSurfaceNormals,
	avl::CurvatureMeasure::Type inCurvatureMeasure,
	float inSmoothingStdDevX,
	atl::Optional<float> inSmoothingStdDevY,
	float inScale,
	float inOffset,
	avl::Image& outSurfaceCurvature
)

Parameters

Name	Type	Range	Default	Description
