Robust and Fast Normal Mollification via Consistent Neighborhood Reconstruction for Unorganized Point Clouds [PDF]

Sensors, 2023
This paper introduces a robust normal estimation method for point cloud data that can handle both smooth and sharp features. Our method is based on the inclusion of neighborhood recognition into the normal mollification process in the neighborhood of the

A Mollification Regularization Method for the Inverse Source Problem for a Time Fractional Diffusion Equation [PDF]

Mathematics, 2019
We consider a time-fractional diffusion equation for an inverse problem to determine an unknown source term, whereby the input data is obtained at a certain time. In general, the inverse problems are ill-posed in the sense of Hadamard. Therefore, in this

Homotopy analysis method for discrete quasi-reversibility mollification method of nonhomogeneous backward heat conduction problem

Nonlinear Engineering, 2023
In this article, the inverse time problem is investigated. Regarding the ill-posed linear problem, utilize the quasi-reversibility method first. This problem has been regularized and after that provides an iterative regularizing strategy for noisy input ...
