In the Cartesian coordinate system, we can represent a straight line as y = mx + b by plotting y against x. However, we can also represent this line as a single point in Hough space by plotting b against m. For example, a line with the equation y = 2x + 1 may be represented as (2, 1) in Hough space.

WebOnces 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. Think how to extend the basic Hough line transform to detect circles. Web3 de mai. de 2013 · The transformation from any (x, y) pixel in Fig1 to the (r, θ) representation int Fig2 is the following: r = x.cos (θ) + y.sin (θ) Now, if you lean back and think a bit about Fig2. Every possible line can be represented by a unique r and θ. And further, every pixel on a given line will transform to the exact same r and θ for that line.
