Chan-Vese Attention U-Net: An Attention Mechanism for Robust Segmentation

Chan-Vese Segmentation

While many segmentation methods rely heavily in some way on edge detection, the “Active Contours Without Edges” method by Chan and Vese [7, 9] ignores edges completely. Instead, the method optimally fits a two-phase piecewise constant model to the given image. The segmentation boundary is represented implicitly with a level set function, which allows the segmentation to handle topological chang...

A Concurrent SOM-Based Chan-Vese Model for Image Segmentation

Concurrent Self Organizing Maps (CSOM s) deal with the pattern classification problem in a parallel processing way, aiming to minimize a suitable objective function. Similarly, Active Contour Models (ACM s) (e.g., the Chan-Vese (CV ) model) deal with the image segmentation problem as an optimization problem by minimizing a suitable energy functional. The effectiveness of ACM s is a real challen...

A local region-based Chan-Vese model for image segmentation

In this paper, a new region-based active contour model, namely local region-based Chan–Vese (LRCV) model, is proposed for image segmentation. By considering the image local characteristics, the proposed model can effectively and efficiently segment images with intensity inhomogeneity. To reduce the dependency on manual initialization in many active contour models and for an automatic segmentati...
