use. Usually a group sport is performed in an Human motion recovery and modeling is a demanding technique in various areas such as sports, dancing, virtual reality, video game producing, etc. But the people in this area focus their efforts more on motion recovery of a single person than a group of persons. In this paper, a technique is described for recovering 3-D motions of a group of persons ...

In this paper, a new object recognition algorithm employing a curvature-based histogram is presented. Recognition of three-dimensional (3-D) objects using range images remains one of the most challenging problems in 3-D computer vision due to its noisy and cluttered scene characteristics. The key breakthroughs for this problem mainly lie in defining unique features that distinguish the similari...

The paper aims at designing a novel scheme for sensory data fusion by a mobile robot for reconstructing its 3-D world from their multiple gray images. Extended Kalman filter has been employed for determining the coordinates of the 3-D vertices and equation of the planes of the obstacles in the robot’s workspace from their multiple images. The geometric relations among these 3-D planes are then ...

A unified biomimetic approach to the aglain-forbaglin-rocaglamide classes of natural products is reported. The approach involves photogeneration of oxidopyryliums via excited-state intramolecular proton transfer (ESIPT) of 3-hydroxyflavones followed by [3+2] dipolar cycloaddition to the aglain core. An alpha-ketol (acyloin) rearrangement was employed to transform the aglain core to the rocaglam...
