In this paper, we present a methodology of locating 3D objects of known shapes from a single gray-scale image, in particular objects with rich textures on the surface. While traditional approaches identify objects by grouping and matching local featu

In wireless systems where half duplex transceivers are employed, most existing practical cooperative protocols achieve a spectral efficiency of 0.5 symbols per channel use (pcu). Recently a decode-and-forward protocol was developed to achieve a spect
