基于变分法的图像分割的数值算法(英文)
Numerical algorithm for image segmentation based on variational method
【摘要】 解释一种图像分割问题的数学模型 ,并讨论图像分割问题与Mumford Shah泛函的关系 ,对此问题首先就一维的情形提出一种可行的解法并推广到二维。若干试验结果验证了算法的有效性。
【Abstract】 A mathematical model for image segmentation is presented. The link between Mumford-Shah’s functional and image segmentation is discussed. As there is not an effective numerical method to solve this problem, a feasible algorithm for the variational problem in 1D is developed and then it is extended to 2D (image). A few experimental results proved the efficiency for the case of 1D and 2D.
