Java program for contouring images


I am trying to write a program in Java that will be able to recognise the contour of an image. An image is a two-dimentional table of boolean values (true=black, false=white), and the contour is the list of points which form the outer edge of the image.

Two files are attached. The first is my class Image, and the second is a test class which tries it out on an example. As you can see if you execute my program, I get a list of points and directions, but they are not quite correct.

I think there are only small changes to be made, and I would be very grateful if you could show me what to change so that it works properly.

Thanks for your help!

PS - In order to compile and execute the attachments, you have to change the name of the files from Image.txt to, and from Test.txt to I had to save them as .txt, otherwise Brainmass wouldn't allow me to attach them!
