A Variational Image Segmentation Model based on Normalized Cut with Adaptive Similarity and Spatial Regularization

no code implementations6 Jun 2018 Faqiang Wang, Cuicui Zhao, Jun Liu, Hai-yang Huang

Thus, the segmentation results of the existing Ncut method are largely dependent on a pre-constructed similarity measure on the graph since this measure is usually given empirically by users.
