Report title: Variational Energy Function Image Segmentation Model and Applications

Speaker: Prof. Zhifeng PANG (Henan University)

Report time: 9:30-11:00, September 4, 2023

Location:Room702,Huixing Building

Report Content: Two new types of variational energy flooding models are proposed for segmentation problems in medical and natural images. Since the proposed models are non-smooth optimization problems, they are solved by the classical operator splitting type method, and numerical comparisons verify the reasonableness of the models and algorithms.
