Abstract: Due to the large scale of the image data，the standard Support Vector Machine（SVM） has a high time complexity in the training process for image segmentation.In this paper，the Ball Vector Machine（BVM） is used for image segmentation in order to reduce the training time.The experimental results show that BVM has a similar segmentation effect and anti-noise performance compared to the standard SVM for image segmentation in the condition of noisy and non-noisy.However，BVM significantly consumes less training time than the standard SVM.BVM can greatly improve the overall performance of image segmentation.
