A novel fuzzy Hough transform for shape representation
Soodamani Ramalingam, Z.Q. Liu · 2002
Three techniques of straight line Hough transform are proposed by a generalised mathematical formulation of the Hough transform in terms of aggregation and weight functions. Amongst these techniques, inclusive of the conventional Hough transform, it is shown by experimental results on a set of 3D nonparametric objects, and in a controlled and inherent noise environment, that the fuzzy Hough transform approach performs the best, as a global shape descriptor.
