Point cloud filtering, the main bottleneck of which is removing noise (outliers) while
preserving geometric features, is a fundamental problem in 3D field. The two-step schemes …

The need for efficient normal integration methods is driven by several computer vision tasks
such as shape-from-shading, photometric stereo, deflectometry. In the first part of this survey …

This paper presents a surface normal integration method that solves an inverse problem of
local plane fitting. Surface reconstruction from normal maps is essential in photometric …

The need for an efficient method of integration of a dense normal field is inspired by several
computer vision tasks, such as shape-from-shading, photometric stereo, deflectometry …

Photometric 3D-reconstruction techniques aim at inferring the geometry of a scene from one
or several images, by inverting a physical model describing the image formation. This …

Photometric stereo is a fundamental technique in computer vision known to produce 3D
shape with high accuracy. It uses several input images of a static scene taken from one and …

Long-term evolutions of parabolic partial differential equations, such as the heat equation,
are the subject of interest in many applications. There are several numerical solvers marking …

A wide range of research areas have high expectations for the technology to measure 3D
shapes, and to reconstruct the shape of a target object in detail from multiple data. In this …

One of the main problems faced by the photometric stereo method is that several
measurements are required, as this method needs illumination from light sources from …

We propose a new SFS (shape from shading) technique for improved 3D surface
reconstruction and imaging of relatively smooth surface topography using the scanning …
