Circle Detection in MATLAB Environment

Detecting circles in MATLAB typically involves processing binary images after binarization, for example using edge detectors. Standard functions usually require specifying the exact circle radius. The circle_hough function enables circle detection by specifying a range of radii, eliminating the need for precise prior knowledge of the radius. This approach can be faster than repeatedly calling standard functions with different radii. The algorithm can detect multiple circles by finding peaks in a 3D accumulator array, with circle_houghpeaks function provided for peak detection and circle parameter extraction.
