This paper presents a simple and effective solution to the longstanding classical multi-view
photometric stereo (MVPS) problem. It is well-known that photometric stereo (PS) is …

This paper studies the discontinuity preservation problem in recovering a surface from its
surface normal map. To model discontinuities, we introduce the assumption that the surface …

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 near-light photometric stereo method for spatially varying
reflectances. Recent studies in photometric stereo proposed learning-based approaches to …

Featured Application The algorithms proposed in this paper can be applied to a wide range
of infrastructure projects in the pre-survey process with the advantages of low cost and high …

Precision measurement and reconstruction of detailed surfaces topography is a challenging
task for non-diffuse complex parts. Although coordinate measurement machines (CMM) with …

Lidar measurements and UAV photogrammetry provide high-resolution point clouds well
suited for the investigation of slope deformations. Today, however, the information contained …

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 …

This paper presents a photometric stereo method that works with unknown natural
illumination without any calibration objects or initial guess of the target shape. To solve this …

This study explores the use of photometric techniques (shape-from-shading and
uncalibrated photometric stereo) for upsampling the low-resolution depth map from an RGB …
