Parametric Model
- Parametric model can represent a class of instances where each is defined by a value of the parameters(e.g. Lines, circles, or even a parameterized template)
- Fitting a parametric model
(a) Choose a parametric model to represent a set of features
(b) Membership criterion is not local: Can’t tell whether a point in the image belongs to a given model just by looking at that point.
(c) Computational complexity is important: Not feasible to examine possible parameter setting.
