Abstract: Systems and methods which provide generation of image depth maps which more accurately represent the local depth discontinuity within images through use of image global depth maps adapted based upon image global motion and/or localized depth analysis utilizing relative relationships of attributes across depth discontinuities in the image are disclosed. Embodiments utilize a full global depth map which is larger than or equal to the image being converted in order to accommodate image global motion, in generating an image global depth map. In operation according to embodiments, an image global depth map is identified within the full global depth map, such as based upon global motion within the image. Localized depth analysis, using pixel attribute relative relationships, is applied with respect to the image global depth map according to embodiments to generate an image depth map which more accurately reflects the local depth discontinuities within the image.

Abstract: The present embodiments are directed to systems and methods for detecting random access channel requests, while excluding false random access signals using search windowing and distance-based peak suppression techniques. The present embodiments additionally include further techniques for suppression of fake random access signals, including amplitude thresholds and preamble-based signal exclusion. Beneficially, the present embodiments significantly reduce the false alarm rate, while maintaining a low hardware complexity requirements. In some embodiments, worst-case false alarm rates can be reduced from as much as 20% down to nearly 0.1%.

Abstract: Disclosed are systems and methods which establish a referral gateway for facilitating multi-media content, or other rich content, exchange among users and user devices. Embodiments connect a WLAN, or any specific local area network, with a mobile cellular network for efficiently transmitting messages including rich content. In operation, a sending user does not need to download particular content to form a message, but instead sends a code to a referral gateway which compiles the message and arranges for delivery, such as over a fixed network, a cellular network, etcetera. Using such systems and methods neither the receiver nor the sender are limited by their respective network and/or user device capabilities.
