Abstract:

In order to further improve the segmentation accuracy and speed up the segmentation, a 2D Otsu multi-threshold image segmentation scheme based on the adaptive differential evolution algorithm with optional external archive, with neighborhood search (JADE-GL for short). Firstly, aiming at the problem of the original JADE algorithm such as slow convergence speed and easy to fall into local optimum, an improved mutation strategy based on neighborhood radius search is proposed to improve the global exploration and development ability of the algorithm. Then, the propesed algorithm is compared with existing segmentation methods and other JADE variant algorithms for 2D Otsu multi-threshold segmentation comparison experiments. Finally, the performance of the algorithm is quantitatively analyzed by function convergence curve, segmentation distance measure and peak signal to noise ratio (PSNR). The experimental results show that the proposed algorithm has more significant advantages in terms of convergence speed, segmentation accuracy and the effect of segmentation images as the number of thresholds increases.

Key words: image segmentation, 2D Otsu, multi-threshold, neighborhood search, adaptive differential evolution algorithm with optional external archive (JADE)
