public CityLandscapeUtilities()

Method Detail

main

public static void main(String[] args)

The main method

Parameters:

args -

runClassifier

public static void runClassifier(String[] args)
                          throws IOException

Method to utilize all necessary classification methods in correct order with given mode which specifies the classifier to be used (loads correct training set). String array args is unchanged from the command line

Parameters:

args -

Throws:

IOException

getOutput

public static String getOutput(org.openimaj.classifier.citylandscape.RecordDetail[] details,
               int output,
               int mode)

Calculates and returns message of given record detail array. Classifier is weighted so that images more closely related to a given image have more classification weighting. This is calculated by 1

Parameters:

details - the records to describe

output - the output mode

mode - the mode

Returns:

the description

classifyImage

public static org.openimaj.classifier.citylandscape.RecordDetail[] classifyImage(ArrayList<Double> query,
                                                                 int k,
                                                                 int mode)

Takes query vector to compare with integer k images from the training set

Parameters:

query - the query vector

k - the number of neighbours

mode - the mode

Returns:

the top k matching records

getImageVector

public static ArrayList<Double> getImageVector(String imageName)

Returns an ArrayList of which each index represents one element of a edge direction coherence vector

Parameters:

imageName -

Returns:

the EDCV

isValidDirectory

public static boolean isValidDirectory(String name)

Checks whether a given directory contains valid images for classification

Parameters:

name -

Returns:

true if valid; false otherwise

isImage

public static boolean isImage(String fileName,
              boolean output)

Obtains a files MIME type and returns true if it is of type image

Parameters:

fileName -

output -

Returns:

true if an image; false otherwise
