This paper describes a new approach to realize grasping of an unknown object by a dexterous hand robot among freely placed multiple unknown objects even if they are occluded each other. This technology consists of major three functions: 1) image-based 3D reconstruction and separation of multiple objects using graph-cut theory, 2) recognition of the shape,(More)
Object recognition technology has matured to a point at which exciting applications are becoming possible. Indeed, industry has created a variety of computer vision products and services from the traditional area of machine inspection to more recent applications such as video surveillance, or face recognition. In this chapter, several representatives from(More)
In this paper, we present a new approach for scene understanding by an autonomous robot, using imaging sensors only. Our goal is to build in real-time a 3D representation of the scene which is suitable for further 3D interaction. We assume the scene is composed of a mix of known and unknown objects. We present a strategy to automatically build online a(More)
