| Abstract | ||
| Image segmentation is an initiative with massive interest in many imaging applications, such as medical images and computer vision. It is considered as a challenging problem, so we need to develop an efficient, fast technique for medical image segmentation. In this paper, the proposed framework is based on two segmentation methods: Fractional-order Darwinian Particle Swarm Optimization (FODPSO) and Mean Shift segmentation (MS). FODPSO is a favorable method for specifying a predefined number of clusters and it can find the optimal set of thresholds with a higher between-class variance in less computational time. In the pre-processing phase,the MRI image is filtered and the skull is removed. In the segmentation phase, the result of FODPSO is used as the input to MS. Finally, we make a validation to thesegmented image. We compared our proposed system with some state of the art segmentation techniques using brain benchmark data set. The experimental results show that the proposed system enhances the accuracy of the MRI brain image segmentation. | ||
