阈值分割是图像处理中频繁使用的基本灰度变换,把阈值分割方法与Chan-Vese模型进行结合,并用尺度变换的方式加以辅助,以提高Chan-Vese模型的分割速度和效果。实验表明:该方案大大提高了Chan-Vese模型的收敛速度和分割效果,而且重点改善了Chan-Vese模型在图像灰度变化缓慢的边界迭代次数较多、演化速度慢等问题。
Threshold segmentation is a basic grey-scale converting technology of image processing.We combine threshold segmentation with Chan-Vese model with an accompanying scale transformation to improve the segment speed and effect.Experimental results show that this program greatly enhances the convergent speed of the Chan-Vese model,and it focuses on changing the defects of more iterative times and low diffusion speed of Chan-Vese model on the border of the image when its grayscale changes slowly.
