報告題目:Minimizing Curvatures for Image Processing
摘要:The curvature regularities are well-known for providing strong priors in the continuity of edges, which have been applied to a wide range of applications in image processing and computer vision. However, these models are usually non-convex, non-smooth, and highly nonlinear, the first-order optimality condition of which are high-order partial differential equations. Thus, numerical computation is extremely challenging. We study different curvature-based regularization methods for image processing tasks, and develop efficient algorithms based on the alternating direction method of multipliers. Numerical experiments on various image reconstruction problems are considered including MR reconstruction, image restoration, inpainting and segmentation.
