Method Detail

build

public void build(java.lang.String file,
                  HaarReader haar,
                  double varianceToExplain)
           throws java.io.FileNotFoundException,
                  java.io.IOException

Builds a CLM model from a set of images listed in a file

Parameters:

file - the name of the image list file

haar - a face detector

varianceToExplain - the amount of variance in the patch model

Throws:

java.io.FileNotFoundException

java.io.IOException

delineate

public Template delineate(java.awt.image.BufferedImage bimg,
                          HaarReader haar,
                          Template template,
                          ImageZoomPanel izp)
                   throws PowellException

Delineate am image using this CLM

Parameters:

bimg - the image to delineate

haar - the face detector

template - used to initialise if not null

izp - the image zoom panel to use if animating the searcg

Returns:

returns the estimated template

Throws:

PowellException

getStrip

public FloatImage getStrip(Template tem,
                           FloatImage fimg,
                           java.awt.Rectangle rect)

Gets the patches from all points arranged in a strip

Parameters:

tem - the current template

fimg - the image to sample the patches from

rect - the face detection rectangle, if not null this indicates that the priors should be updated

Returns:

returns the patch strip image

project

public FloatImage project(FloatImage strip)

Projects the sampled patches into the patch model space

Parameters:

strip - the current patch strip

Returns:

returns the closest model patch to the one supplied

processPatches

public boolean processPatches(double varianceToExplain)

Builds the patch PCA model

Parameters:

varianceToExplain - the amount of variance to exmplain in the model

Returns:

returns true if the method was able to build a model, or false if not

read

public void read(java.lang.String file)
          throws java.io.IOException

Reads CLM data from a directory

Parameters:

file - The text file containing the names of the image component files and their variance

Throws:

java.io.IOException - if the file can't be read

write

public void write(java.lang.String file)
           throws java.io.IOException

Writes PCI data to a directory

Parameters:

file - The text file containing the names of the image component files and their variance

Throws:

java.io.IOException - throws IOException if problem writing file
