Description and recognition of curved objects
WebAug 30, 1992 · The author presents an approach to the approximation of curves for the description and recognition of curved objects. One needs only to make a rotation and a … WebThe recognition system is extended to recognize and locate curved objects. The extension is done in two dimensions, and applies to the recognition of 2-D objects from 2-D data, or to the recognition of the 3-D objects in stable positions from 2-D data. References {1} H.

WebDec 1, 1988 · A robotic system for object recognition is described that uses passive stereo vision and active exploratory tactile sensing. The complementary nature of these sensing modalities allows the system to discover the underlying 3 … WebAbstract This paper describes data structures and algorithms for the automatic generation of adaptive subgrids, a technique used with adaptive mesh refinement for solving partial differential equations. Our algorithms generate a nested sequence of finer and finer grids on an underlying coarse grid. There are two aspects to the data structures.
Webincluding curved objects, using relations within a two-dimensional image. However, none of these efforts really addresses the problem of "shape" representation and description. Work on outdoor scene analysis is also concerned with non-polyhedral objects ([Bajcsy], [Yakimovsky]), but again no attention has been paid to shape analysis. WebThis paper describes two similar algorithms one for learning descriptions of objects the other for recognizing partial views of known objects. The input to either algorithm is a two-dimensional array in which the boundaries of the surfaces of the object are marked. Both algorithms use a library of known objects. The learning algorithm sees the whole object …
WebThe complexity of objects used is that of toy animals and hand tools. Recognition is performed by matching these descriptions with stored descriptions of models. A laser … WebAbstract: A method for the description and identification of curved objects is described in this paper. The shape of a curved object is considered as a surface which is an …
WebThis paper discusses how local measurements of three- dimensional positions and surface normals ( recorded by a set of tactile sensors, or by three-dimensional range sensors ), may be used to identify and locate objects from among a set of known objects.
