1. Installing Octave3.2
    
    Install octave3.2 and octave3.2-headers
    Then go to pkgs directory, enter octave3.2 shell
    Type in 'pkg install image.tar.gz'. Using the same way to install strings.

2. Run the program
    
    octave3.2 -q main.m 5 3 100
    5 - k value in KNN
    3 - Shrinking original image 3 times before dimensionality reduction
    100 - Optional. Manually set the reducted dimension d to 100.

3. Troubleshotting

    If matrices dimensions are not matched, try 'rm imageDb.data' and run the program again.
