A nonlinear multigrid method for total variation minimization from image restoration
Image restoration has been an active research topic and variational formulations are particularly effective in high quality recovery. Although there exist many modelling and theoretical results, available iterative solvers ...
Noise removal using smoothed normals and surface fitting
In this work, we use partial differential equation techniques to remove noise from digital images. The removal is done in two steps.We first use a total-variation filter to smooth the normal vectors ...
A unified framework for automated 3D whole cell segmentation of living cells and a comprehensive segmentation
This work presents a unified framework for whole cell segmentation of surface stained living cells from 3-D data sets of fluorescent images. Every step of the process is described, image acquisition, prefiltering, ridge ...
A binary level set model and some applications to Mumford-Shah image segmentation
In this paper, we propose a PDE-based level set method. Traditionally, interfaces are represented by the zero level set of continuous level set functions. Instead, we let the interfaces be represented by discontinuities ...
