In observing a virtual 3D object displayed stereoscopically on a large screen, there often exists a difference between the calculated depth and the perceived depth of an object. This paper presents a method for reducing such differences of depth. This is performed by modifying both the viewing position and the screen position in the stereoscopic(More)
We had been researching and developed the original caricature generation system PICASSO. We realized an automated PICASSO system called PICASSO-2. We exhibited the robot that used PICASSO-2 system in the named COOPER in which PICASSO-2 is fabricated, at Aichi Expo EXPO2005. This robot acquires the face image of the visitor, extracts the facial features(More)
It is undesirable for car designers to wait long for a physical mockup, or to learn a difficult CAD interface. This paper presents a Spatial Sketch System that provides a sketch-like modeling interface, and realizes 3D drawing for human oriented industrial design, such as car styling. The designer can draw lines and surfaces directly and freely in the(More)
We have not yet completed the automatic recognition of facial parts by image processing. Even if once we get the edge image for the contour of facial parts, due to the existence of the noise, the results are quite frequently not sufficient both in local and global aspects. This is caused mainly by the lack the top-down mechanism for compensating the(More)
Tracking the maximum power point (MPP) of a photovoltaic array is an essential operation for any PV system. Thus, changing the environmental conditions causes different maximum power point (MPP) driving for non-uniform power feeding for the load. So, researchers have developed many MPPT algorithms to maximize and stabilize the power derived for the load.(More)
