Syntax

[SerializableAttribute]
[XmlRootAttribute("_")]
public class HaarCascadeStage : ICloneable

<SerializableAttribute>
<XmlRootAttribute("_")>
Public Class HaarCascadeStage
	Implements ICloneable

The HaarCascadeStage type exposes the following members.

Constructors

	Name	Description
	HaarCascadeStage	Constructs a new Haar Cascade Stage.
	HaarCascadeStage(Double)	Constructs a new Haar Cascade Stage.
	HaarCascadeStage(Double, Int32, Int32)	Constructs a new Haar Cascade Stage.

Properties

	Name	Description
	NextIndex	Gets the index of the next stage from this stage.
	ParentIndex	Gets the index of the parent stage from this stage.
	Threshold	Gets or sets the threshold associated with this stage, i.e. the minimum value the classifiers should output to decide if the image contains the object or not.
	Trees	Gets or sets the feature trees and its respective feature tree nodes which compose this stage.

Methods

	Name	Description
	Classify	Classifies an image as having the searched object or not.
	Clone	Creates a new object that is a copy of the current instance.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Extension Methods

	Name	Description
	HasMethod	Checks whether an object implements a method with the given name. (Defined by ExtensionMethods.)
	IsEqual	Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)
	To(Type)	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
	ToT	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)

Remarks

A Haar Cascade Classifier is composed of several stages. Each stage contains a set of classifier trees used in the decision process.
