Detect circles with various radii in grayscale image via Hough Transform
Nota del editor: This file was selected as MATLAB Central Pick of the Week
Circular Hough transform based on the gradient field of an image.
1. Operates on grayscale images, NOT B/W bitmaps.
2. NO loops in the implementation of Circular Hough transform, which means faster operation but at the same time larger memory consumption.
3. Detection of radii works for concentric circles as well.
