CompareGoldenTemplate2


Header: AVL.h
Namespace: avl
Module: FoundationPro

Compares an image with a multi-image model using an ensemble of image features approach.

Applications: Finding general object defects by analyzing brightness deviations from a template image.

Syntax

C++
C#
 
void avl::CompareGoldenTemplate2
(
	const avl::Image& inImage,
	const avl::GoldenTemplate2Model& inModel,
	float inSensitivityA,
	float inSensitivityB,
	avl::Region& outDefects
)

Parameters

Name Type Range Default Description
Input value inImage const Image& Input image
Input value inModel const GoldenTemplate2Model&
Input value inSensitivityA float 0.0 - 1.0f Usually influences small, distinctive defects.
Input value inSensitivityB float 0.0 - 0.95f Usually influences bigger, extensive defects.
Output value outDefects Region&

Description

This filter compares pixels of the input images against a template created by CreateGoldenTemplate2 and creates a region containing only pixels that are different.

The filter expects the object to be positioned precisely and in the same way as object images used to construct the inModel - see CreateGoldenTemplate2.

Sensitivity of the filter can be adjusted using inSensitivityA and inSensitivityB parameters.
