IconMemberDescription
EigenObjectRecognizer(array<Image<(Of <(Gray, Byte>)>)>[]()[], MCvTermCriteria%)
Create an object recognizer using the specific tranning data and parameters, it will always return the most similar object

EigenObjectRecognizer(array<Image<(Of <(Gray, Byte>)>)>[]()[], array<String>[]()[], MCvTermCriteria%)
Create an object recognizer using the specific tranning data and parameters, it will always return the most similar object

EigenObjectRecognizer(array<Image<(Of <(Gray, Byte>)>)>[]()[], array<String>[]()[], Double, MCvTermCriteria%)
Create an object recognizer using the specific tranning data and parameters

AverageImage
Get the average Image.

CalcEigenObjects(array<Image<(Of <(Gray, Byte>)>)>[]()[], MCvTermCriteria%, array<Image<(Of <(Gray, Single>)>)>[]()[]%, Image<(Of <(Gray, Single>)>)%)
Caculate the eigen images for the specific traning image

EigenDecomposite(Image<(Of <(Gray, Byte>)>), array<Image<(Of <(Gray, Single>)>)>[]()[], Image<(Of <(Gray, Single>)>))
Decompose the image as eigen values, using the specific eigen vectors

EigenDistanceThreshold
Get or set the eigen distance threshold. The smaller the number, the more likely an examined image will be treated as unrecognized object. Set it to a huge number (e.g. 5000) and the recognizer will always treated the examined image as one of the known object.

EigenImages
Get the eigen vectors that form the eigen space

EigenProjection(array<Single>[]()[])
Given the eigen value, reconstruct the projected image

EigenValues
Get the eigen values of each of the training image

Equals(Object)
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Finalize()()()
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
FindMostSimilarObject(Image<(Of <(Gray, Byte>)>), Int32%, Single%, String%)
Given the image to be examined, find in the database the most similar object, return the index and the eigen distance

GetEigenDistances(Image<(Of <(Gray, Byte>)>))
Get the eigen distance between image and every other image in the database

GetHashCode()()()
Serves as a hash function for a particular type.
(Inherited from Object.)
GetType()()()
Gets the Type of the current instance.
(Inherited from Object.)
Labels
Get or set the labels for the corresponding training image

MemberwiseClone()()()
Creates a shallow copy of the current Object.
(Inherited from Object.)
Recognize(Image<(Of <(Gray, Byte>)>))
Try to recognize the image and return its label

ToString()()()
Returns a String that represents the current Object.
(Inherited from Object.)
