CreateImagePyramid_Gauss


Header: FIL.h
Namespace: fil
Module: FoundationBasic

Creates an array of images, each downsampled from the previous, gauss-smoothed one.

Applications: Frequently used to create scale-invariant image analysis algorithms. Reduces impact of pixel aliasing.

Syntax

C++
C#
 
void fil::CreateImagePyramid_Gauss
(
	const fil::Image& inImage,
	fil::GaussKernel::Type inGaussKernelSize,
	int inMinPyramidLevel,
	int inMaxPyramidLevel,
	fil::DownsampleFunction::Type inFunction,
	ftl::Array<fil::Image>& outImagePyramid
)

Parameters
