    摘要: A method and system for reducing noise in image and audio signals for processing and output display includes determining noise estimates for a given signal and performing a noise reduction routine for two adjacent data in a signal array. By using a predetermined conversion factor and a permissible delta (deviation) between the two adjacent data, energy may be shifted from the higher valued data to the lower valued data to reduce the noise level without changing the total intensity of the signal array (corresponding to image and/or audio data).

    摘要: A group of wireless device users are notified of an event. A location data determination algorithm is provided to a wireless device, where the algorithm determines a frequency at which the device interacts with network elements to determine its location. The location data is stored in a notification server and used to identify a user at a specific location. When a governmental or commercial entity wishes to issue a notification, a message is provided to those users whose location is identified as being in an area defined by the entity.
