| 摘 要： | 针对被噪声严重污染的图像的分割结果很不理想的现象, 提出一类耦合去噪-分割的新模型, 先采用一种组合的去噪模型去噪, 然后用新的分割模型进行分割。实验结果表明, 提出的组合去噪模型(采用AOS算法)比现有的一些去噪模型的去噪效果更好; 而在分割方面，文中提出的耦合去噪-分割的方法也显示出有效性和可靠性, 特别是对含有较高噪声的图像分割比CV模型更有优势。 |

| Abstract: | Due to dissatisfactory results of segmenting the images corrupted by serious noise, a new model coupling denoising and segmentation is proposed. The image is denoised by a fused denoising model, then the denoised image is segmented by a novel segmentation model. Experimental results show that the proposed denoising model (by using AOS schemes)is better than some traditional denoising model .Moreover the excellent segmentation results of some high noise images show that the proposed model coupling denoising and segmentation is effective and reliable and it has an advantage over CV model in segmentation. |
| Keywords: | image denoising image segmentation coupling model |
