This survey paper discusses the three-dimensional image processing challenges posed by
present and future immersive telecommunications, especially immersive video conferencing …

We propose a method for analyzing photometric factors, such as diffuse reflection, specular
reflection, attached shadow, and cast shadow. For analyzing real images, we utilize the …

Owing to human labor shortages, the automation of labor-intensive manual waste-sorting is
needed. The goal of automating waste-sorting is to replace the human role of robust …

For object recognition under varying illumination conditions, we propose a method based on
photometric alignment. The photometric alignment is known as a technique that models both …

Tubes are used widely in aerospace vehicles, and their accurate assembly can directly
affect the assembling reliability and the quality of products. It is important to measure the …

We propose a new method for synthesizing an illumination normalized image from a face
image including diffuse reflection, specular reflection, attached shadow and cast shadow …

This chapter focuses on correctly recognizing faces in the presence of large illumination
variation. Our aim is to do this by synthesizing an illumination normalized image using …

In mixed reality, especially in augmented virtuality which virtualizes real objects, it is
important to estimate object surface reflectance properties to render the objects under …

In this paper, we introduce the Virtual Photometric Environment which is one of mixed reality
systems. The Virtual Photometric Environment enables arbitrarily control over the lighting …

Abstract Shape from Shading and Photometric Stereo are famous approaches to recover the
3D shape from image (s). These approaches can obtain 3D shape from observed gray scale …
