A comparison between the standard Hough Transform and the Mahalanobis distance Hough Transform,is paper presents two related techniques. First, a new Hough function is proposed based on a Mahalanobis distance measure that incorporates a formal stochastic model for measurement and model noise. Thus, the effects of image and parameter space quantisation can be incorporated directly. Given a res作者: ALIBI 時(shí)間: 2025-3-23 03:01
