Abstract :
Presents a model based method to recognize objects. Firstly hypotheses are generated from shape primitives and (their) Boolean operations to predict a complex object, and then are verified by finding the minimum cost in parameter space. A number of optimization techniques are considered and then applied to practical search on real-world data. The authors emphasize parameter estimation and consider the procedure as a numerical optimization problem. A technique for finding global minima is reported, and its efficiency is proven by applying the method for recognition of landuse patches in images of agricultural fields
