A multiphase image segmentation model with the noise removal ability is proposed based on the variational level set mehod. The new model can complete the segmentation and the denoising process simultaneously. Therefore it can reduce the execution time of image segmentation. On the other hand, we construct the characteristic function of the regional division based on the decimal-binary number conversion. Finally, the proposed model is applied to the segmentation of the synthetic images and medical images. The experimental results show that the proposed model can extract the targets from the noise image faster than Chan-Vese model.
