Beginners need a long time before being able to play correctly violin. Learning the bowing technique appears to be a difficult task and retains most of the attention of beginners. Besides this point, the finger placement is also an important part of the learning but often under estimated. One difficulty is that the fingerboard of the violin does not have frets. In this on-going work, we present a...
Optical consistency between the real world and the virtual objects is one of the important issues in Augmented Reality (AR). This paper proposes a method to estimate illuminations from an object shadow and incomplete object shape information captured by an RGB-D camera. The environmental illumination can be estimated without any prior knowledge of the object shape. The radiance of each light source...
A calibration method for a structured light system by observing a planar object from unknown viewpoints is proposed. A structured light system captures a 3D shape by a camera that observes a light stripe on an object illuminated by a projector. The 3D shape, obtained from the system defined by a pinhole model for the projection of a light stripe, is solved using the equation of a plane model for the...
