Java Hough Transform for lines and circles

Generate hough transform accumulator images for lines and circles from a BufferedImage. Every pixel lower the threshold can be assumed as black. The output should be a gray scaled image. A basic image processing project. Have a look to these pages as a reference:

[url removed, login to view]

[url removed, login to view]

[url removed, login to view] houghTransformLineAcc

=? gethoughTransformLineAccImage(int threshold; [url removed, login to view] inputImage);

[url removed, login to view] houghTransformCircleAcc

=? gethoughTransformCircleAccImage(int threshold; double radius, [url removed, login to view] inputImage);

Inverse to this I need a function which generates a line or circle image from a hough transform accumulator image. A threshold affects the lines or circles to generate. The background of the inverse image should be black and the lines and circles should be white.

[url removed, login to view] image

=? getImageFromLineAcc (int threshold; [url removed, login to view] houghTransformLineAcc);

[url removed, login to view] image

=? getImageFromCircleAcc (int threshold; [url removed, login to view] houghTransformCircleAcc);

You don't need to generate a GUI. You should generate a main function to test your source.

You can create a command line application and read/write images as a from a file. Each function should be tested. Your source code has to be free.

## Deliverables

Java / Eclipse

Efficient algorithm

Windows XP and Windows 7

Only free source code

You have to test your solution!
