| Abstract: This paper proposes a new portrait image segmentation method based on a combination of improved genetic algorithm and threshold image segmentation. Genetic algorithm, which has higher search efficiency and obvious search accuracy, is used as a basis in the new improved method to improve the accuracy acquisition and the anti-noise ability of image segmentation. While increasing the stability of the threshold value, it improves the speed and accuracy of the threshold value acquisition, so to overcome the shortcomings of unsatisfactory segmentation effect and low segmentation accuracy when traditional algorithms are applied to portrait image segmentation. Experiments verify that the improved algorithm in this paper achieves a better segmentation effect and has better anti-noise ability, thereby shortening the image segmentation time. |
