An Addtive Operator Splitting Method for Microscopic Image Segmentation

An additive operator splitting(AOS) method is employed in the geodesic active contours model for image segmentation. The numerical discretization scheme is semi-implicit and unconditional stable if balloon force is not employed. It overcomes the time step size restriction for explicit scheme. The method can easily be parallelized and one can gain an accelerated convergence. The experiments show that it has a great promising compared to the explicit scheme and makes the scheme attractive for applications such as medical image processing.
