Hole-Filling for DIBR Based on Depth and Gradient Information

International Journal of Advanced Robotic Systems, 2015
Depth image-based rendering (DIBR) is a method for generating new virtual images from known viewpoints. However, holes often appear in the rendered virtual images due to occlusion and inaccurate depth information.

An expanded mixed finite element simulation for two-sided time-dependent fractional diffusion problem

Advances in Difference Equations, 2018
In this paper, we consider a time-dependent diffusion problem with two-sided Riemann-Liouville fractional derivatives. By introducing a fractional-order flux as auxiliary variable, we establish the saddle-point variational formulation, based on which we ...

Estimation of Changes of Forest Structural Attributes at Three Different Spatial Aggregation Levels in Northern California using Multitemporal LiDAR

Remote Sensing, 2019
Accurate estimates of growth and structural changes are key for forest management tasks such as determination of optimal rotation times, optimal rotation times, site indices and for identifying areas experiencing difficulties to regenerate. Estimation of

Novel solitonic structure, Hamiltonian dynamics and lie symmetry algebra of biofilm

Partial Differential Equations in Applied Mathematics
In this study, the Lie point symmetries and optimal system have been established. We discuss the biofilm model’s soliton solutions. To examine a nonlinear dynamical biofilm system, which is simply a bistable Allen–Cahn equation with quartic potential, to

The Optimal Auxiliary Functions Method for Semi-Analytical Solutions of the MHD Mixed Convection Stagnation-Point Flow Problem

Symmetry
The present paper treats the problem of steady laminar MHD flow of an incompressible viscous fluid for mixed convection stagnation-point flow over a vertical stretching sheet in the presence of an externally magnetic field. By means of the Optimal Auxiliary Functions Method (OAFM), the resulting nonlinear ODEs are semi-analytically solved.

Near-Optimal Tracking Control of a Nonholonomic Mobile Robot with Uncertainties

International Journal of Advanced Robotic Systems, 2012
A combined kinematic/torque control law is developed by using a backstepping design approach for a nonholonomic mobile robot with two driving wheels mounted on the same axis to track a reference trajectory.
