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.
