WebIn the case where the parameter space for a parameter $\theta$ takes on an infinite number of possible values, a Bayesian must specify a prior probability density function $h(\theta)$, say. Entire courses have been devoted to the topic of choosing a good prior p.d.f., so naturally, we won't go there! WebThe actual step of θ is defined by the function parameter, so if you use the usual math.pi / 180.0 value of theta, the algorithm will compute ρ 180 times in total for just one edge pixel in the image. If you would use a larger theta, there would be fewer calculations, fewer accumulator columns/buckets and therefore fewer lines found.
