Deflectometry as a technique to assess reflective surfaces has now existed for some 40
years. Its different aspects and variations have been studied in multiple theses and research …

The method described here for recovering the shape of a surface from a shaded image can
deal with complex, wrinkled surfaces. Integrability can be enforced easily because both …

The photometric-stereo method is one technique for three-dimensional shape determination
that has been implemented in a variety of experimental settings and that has produced …

There are hundreds of welded studs in a car. The posture of a welded stud determines the
quality of the body assembly, thus affecting the safety of cars. It is crucial to detect the …

Photometric stereo is a fundamental approach in computer vision. At its core lies a set of
image irradiance equations each taken with a different illumination. The vast majority of …

Ductile cast iron pipes (DCIPs) are widely utilized in water and gas supply due to their
exceptional mechanical and material properties. Quality control during production is …

In this work we present a novel multi-view photometric stereo (PS) method. Like many works
in 3D reconstruction we are leveraging neural shape representations and learnt renderers …

Leaf venation extraction studies have been strongly discouraged by considerable
challenges posed by venation architectures that are complex, diverse and subtle …

We describe a technique for surface recovery of a rotating object illuminated under a
collinear light source (where the light source lies on or near the optical axis). We show that …
