3D-reconstruction is one of the most classic computer vision tasks. The term stereovision, which etymologically means vision of 3D-shapes, is often confused with stereoscopy, which is one technique of 3D-reconstruction among others. The 3D-reconstructions obtained by recent projects like PMVS (Patch-based Multi-view Stereo), CMVS (Clustering Views for Multi-view Stereo), ARC (Automatic Reconstruction Cloud) or Photosynth, which all rely on stereoscopy, are indeed very impressive.

However, such softwares are not guided by accuracy considerations, and are more destined to augmented reality than to industrial applications, which requires accurate 3D models.

The proposed workshop is dedicated to another computer vision technique than stereoscopy, named Photometric Stereo (PS), which uses the camera sensor as a measuring instrument. Moreover, the images are taken under very controlled conditions. This is why PS is considered as an active vision technique, as opposed to passive vision.

All contributions related to PS are welcome, from theory to industrial applications. More precisely, please find hereafter a (non-exhaustive) list of topics which will be favorably considered:

• PS models
• PS with 1 image (shape-from-shading) or 2 images
• Uncalibrated PS
• PS under general lightings
• PS in the presence of shadows
• Integration of normals/gradients
• PS for non-opaque objects
• Outdoors PS
• Coupling PS with other 3D-reconstruction techniques
• Industrial applications of PS
