Abstract
The use of Differential Evolution (DE) to simultaneously optimize parameter t and middle control points (P1 and P2) of cubic Bézier curve is presented in this paper. The main objective of this research is to reduce the error of the numerical result. In addition, the numerical result from this research also being compared with the previous article [4] and [5]. The main steps involved are boundary extraction and corner point detection of the images. Then, followed by the process of DE in optimizing the parameter t and middle control points. Finally, by using the optimized value, the piecewise cubic Bézier curve is fitted to each segment. In addition, the Sum Square Error (SSE) has been used as an objective function to calculate the distance of the fitted Cubic Bézier curve with the boundary of the original images. The numerical result for this research produced more errors because of two parameter value that were optimized has been run simulataneously. The result that has been obtained does not guarantee that this algorithm is not good because the use of DE is subjective. DE is an interesting algorithm that can be explored in more detail and can be applied in various problems. The new research of DE can be extended more to its various mutation strategies.
