Variational image segmentation using boundary functions

IEEE Transactions on Image Processing, 1998
A general variational framework for image approximation and segmentation is introduced. By using a continuous "line-process" to represent edge boundaries, it is possible to formulate a variational theory of image segmentation and approximation in which the boundary function has a simple explicit form in terms of the approximation function.

The Boundary Functions Method

2000
Consider the following Cauchy problem : $$ \frac{{d{x_1}}}{{dt}} = {F_1}(x,t,\mu ),{\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {x_1}{|_{t = 0}} = x_1^ \circ (\mu ),{\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mu ^{{K_i}}}\frac{{d{x_i}}}{{dt}} = (x,t,\mu ),{\mkern 1mu}

Linked Boundary Functions: Examining the Role of ‘Research for Development’ Organizations in Integrating Levels of Resource Governance

Society & Natural Resources, 2018
Natural resource management practices such as community-based resource management (CBRM) are well-established bottom-up approaches to developing adaptive governance systems.

DeepSDF: Learning Continuous Signed Distance Functions for Shape Representation

Computer Vision and Pattern Recognition, 2019
Computer graphics, 3D computer vision and robotics communities have produced multiple approaches to representing 3D geometry for rendering and reconstruction. These provide trade-offs across fidelity, efficiency and compression capabilities. In this work,

Boundary shape functions methods for solving the nonlinear singularly perturbed problems with Robin boundary conditions

, 2020
For a second-order nonlinear singularly perturbed boundary value problem (SPBVP), we develop two novel algorithms to find the solution, which automatically satisfies the Robin boundary conditions.

Functional twin boundaries

Phase Transitions, 2013
Functional interfaces are at the core of research in the emerging field of ‘domain boundary engineering’ where polar, conducting, chiral, and other interfaces and twin boundaries have been discovered. Ferroelectricity was found in twin walls of paraelectric CaTiO3.
