A study on evolutional shape modeling: parameter tuning

The technique of generating suitable shape model automatically using GA and FFD have already been developed. The technique has proposed using the control points of an FFD lattice as the chromosome representing evolved shapes. In the FFD technique, the shape of an object is deformed by altering the positions of the control points on the FFD lattice. The hybrid evolutional shape modeling system of GA and FFD has brought a fruitful result. However, since various parameters exist in GA and FFD, specification of those parameters is not easy, and the actual condition is depending on a human's intuition. Then, in this paper, in order to brush up the ability of the system, various parameters are tuned up experimentally.
