WebHough Circle. The same idea is applied for other shapes. Onces you have parametric equation that describes the shape you can build parameter space and detect that shape. For the circle. r2 = (x−x0)2 +(y−y0)2. Circle parameters are center (x0,y0) and radius r. Your parameter space now is 3D parameter space. WebJul 18, 2024 · This point-to-curve transform is the Hough transform for straight lines. The transform is implemented by quantizing the Hough parameter space into finite bins or battery cells. When the algorithm runs, each (X, Y) is converted to a sampled (r, 0) curve, and the accumulator cells (2D matrices) that lie along this curve are enlarged.
