New region force for variational models in image segmentation and high dimensional data clustering
Ke Wei, Ke Yin, Xue-Cheng Tai +1
We propose an effective framework for multi-phase image segmentation and semi-supervised data clustering by introducing a novel region force term into the Potts model. Assume the p…
