an improved two-dimensional Otsu algorithm is given through comparing two threshold segmentation algorithms such as traditional two-dimensional Otsu and Otsu double threshold. Aiming at the existing defect of optimal threshold selecting by two-dimensional Otsu algorithm
the overall threshold is redistinguished and combined with the square sum of deviations which is regarded as the fitness function
which can select the best threshold value to boost threshold segmentation effect of the target image. The experimental results show that the proposed algorithm not only meets segmenting the target area on the SF
