Green Image
<p><b>Abstract</b>—This paper compares the Hough Transform and the UpWrite for the detection of lines, circles, and ellipses. Both ideal and noisy images are tested. The UpWrite is found to be more robust for images containing perturbation noise. For ideal images and images with speckle noise, the results are found to depend on the complexity of the object being detected, with more complex objects favoring the UpWrite. A program allowing the reader to experiment with these algorithms can be found at the following World Wide Web address: <url></url>.</p>
