An exact method of correcting the rolling shutter (RS) effect requires recovering the
underlying geometry, ie the scene structures and the camera motions between scanlines or …

Traditional intrinsic image decomposition focuses on decomposing images into reflectance
and shading, leaving surfaces normals and lighting entangled in shading. In this work, we …

We examined visual estimation of surface roughness using random, computer-generated,
three-dimensional (3D) surfaces rendered under a mixture of diffuse lighting and a punctate …

A video stream for a scene for a virtual reality or augmented reality experience may be
stored and delivered to a viewer. The video stream may be divided into a plurality of units …

We present a new approach for generating global illumination renderings of hand-drawn
characters using only a small set of simple annotations. Our system exploits the concept of …

This paper tackles the photometric stereo problem in the presence of inaccurate lighting,
obtained either by calibration or by an uncalibrated photometric stereo method. Based on a …

Lightness perception is the perception of achromatic surface colors: black, white, and
shades of grey. Lightness has long been a central research topic in experimental …

We used functional magnetic resonance imaging to investigate the human cortical areas
involved in processing 3-dimensional (3D) shape from texture (SfT) and shading. The stimuli …
