A Firefly Algorithm for Two-dimensional Grayscale Image Segmentation

To solve the 2-dimensional (2D) grayscale image segmentation problem, a 2D image segmentation method based on the firefly algorithm is proposed in this paper, which uses a Tsallis entropy as an image segmentation evaluation index and solves the optimal threshold by the firefly algorithm to obtain the optimal image segmentation results. The experimental simulation results show that the proposed 2D image segmentation method based on Firefly algorithm image decomposition results are significantly better than other commonly used methods. The proposed method will have certain application value in image segmentation.
