Local Spherical Harmonics for Facial Shape and Albedo Estimation

IEEE Access, 2020
In this paper, we present a novel facial albedo and 3D shape recovery method with a local spherical harmonic illumination model. From a face in an image, the proposed method can produce a high-quality 3D shape and albedo using a novel parameterization of

Data-Driven Shape Analysis and Processing [PDF]

, 2015
Data-driven methods play an increasingly important role in discovering geometric, structural, and semantic relationships between 3D shapes in collections, and applying this analysis to support intelligent modeling, editing, and visualization of geometric

Scalable Dense Monocular Surface Reconstruction

, 2017
This paper reports on a novel template-free monocular non-rigid surface reconstruction approach. Existing techniques using motion and deformation cues rely on multiple prior assumptions, are often computationally expensive and do not perform equally well

A neural network approach for the blind deconvolution of turbulent flows

, 2017
We present a single-layer feedforward artificial neural network architecture trained through a supervised learning approach for the deconvolution of flow variables from their coarse grained computations such as those encountered in large eddy simulations.

Formulation of Heat-Induced Whey Protein Gels for Extrusion-Based 3D Printing

Foods, 2020
This study investigated the extrusion-based 3D printability of heat-induced whey protein gels as protein rich food inks. In particular, the effects of ionic strength by the addition of NaCl (0–250 mM), protein content (10%, 15%, 20%), fat content (0%, 10%
