A Novel Euler's Elastica based Segmentation Approach for Noisy Images via using the Progressive Hedging Algorithm [article]

Lu Tan, Ling Li, Wanquan Liu, Jie Sun, Min Zhang
2019 arXiv   pre-print
Euler's Elastica based unsupervised segmentation models have strong capability of completing the missing boundaries for existing objects in a clean image, but they are not working well for noisy images  ...  This paper aims to establish a Euler's Elastica based approach that properly deals with random noises to improve the segmentation performance for noisy images.  ...  The reason is that in these models there exists a one-toone mapping relationship between the parameters to be evaluated and the noisy images with some probability density distribution.  ...
