Differential evolution (DE) is a simple, effective, and robust algorithm, which has demonstrated excellent performance in dealing with global optimization problems. However, different search strategies are designed for fitness landscape conditions to find the optimal solution, there not single strategy that can be suitable all landscapes. As result, developing adaptively steer population based ...

Active contour models have been widely used in image segmentation, and the level set method (LSM) is most popular approach for solving models, via implicitly representing by a function. However, LSM suffers from high computational burden numerical instability, requiring additional regularization terms or re-initialization techniques. In this paper, we use characteristic functions to represent c...
