org.myrobotlab.opencv.OpenCVFilter

org.myrobotlab.opencv.OpenCVFilterFaceRecognizer

All Implemented Interfaces:

java.io.Serializable

public class OpenCVFilterFaceRecognizer
extends OpenCVFilter

This is the OpenCV Face Recognition. It must be trained with a set of images and their labels. These images should be of people faces and their names are the labels. It computes the "distance" from the reference new image to existing images that it's been trained on and provides a prediction of what label applies Based on: https://github.com/bytedeco/javacv/blob/master/samples/OpenCVFaceRecognizer. java

          throws java.io.IOException

Parameters:

filename - the filename to save the current model to.

Throws:

java.io.IOException

load

public void load()
          throws java.io.IOException

load the model from the default filename specified by faceModelFilename.

Throws:

java.io.IOException

load

public void load(java.lang.String filename)
          throws java.io.IOException

Load a face recognizer model from the provided saved filename.

Parameters:

filename - the filename that represents the saved model.
