融入邻域距离与隶属度模糊聚类图像分割算法

Fuzzy Clustering Algorithm by Incorporating Local Distance and Membership for Image Segmentation

  • 摘要: 为提升图像分割算法的抗噪性和准确性, 提出融入邻域距离与隶属度的模糊聚类算法.首先结合像素邻域灰度信息自适应地对噪声图像进行滤波以构建新的滤波图像, 然后在聚类过程中将像素邻域与聚类中心的距离做平滑处理以提高算法的鲁棒性, 接着为平衡边界与噪声关系对全局隶属度和邻域隶属度进行结合产生新的权重隶属度函数和新的聚类中心, 最后利用加噪的人工合成图像、真实图像进行分割实验.相比其他模糊聚类算法, 从定性方面来看, 所提算法能够去除更多的噪声点, 显示出更好的视觉效果; 从定量方面看, 所提算法在分割准确率和ARI指标上有进一步的提升.

     

    Abstract: Due to limitation of the fuzzy clustering algorthm, a new fuzzy clustering algorithm is proposed by incorporating local distance and membership for image segmentation so as to enhance the segmentation accuracy and robustness. Firstly, combining the neighborhood gray information of pixels, the noise image is adaptively filtered to construct a new filtering image, Secondly, the neighborhood distances between local gray values and clustering centers are smoothed for improving the anti-noise capability, and then a weighted membership function, incorporating local and global spatial membership, is emerged to control the tradeoff between boundary and noise, and as a result the new clustering centers is formed. Finally, the obtained segmentation algorithm is carried out on synthetic image, and real images in different levels of noise. The segmentation results not only can reduce the number of spurious blobs and show better visual effects qualitatively, but also demonstrate the higher segmentation accuracy and ARI quantitatively compared with others common fuzzy clustering algorithms.
