Abstract: Two-dimensional and three-dimensional data of a physical scene are combined and analyzed together to identify physical objects physically present in the physical scene. Image features obtained from the two-dimensional data and geometric features obtained from the three-dimensional data are combined with one another such that corresponding image features are associated with corresponding geometric features. Automated object detection mechanisms are directed to the combination of image and geographic features and consider them together in identifying physical objects from the physical scene.

Abstract: A method and apparatus are provided for modulating a signal. The method includes the steps of providing a radio frequency signal, determining a set of delta-sigma modulation coefficients based upon a frequency of the provided signal and delta-sigma modulating the generated radio frequency signal within a delta-sigma modulator using the generated set of delta-sigma modulation coefficients.
