摘要： An image processing system comprises an image processor implemented using at least one processing device and adapted for coupling to an image source, such as a depth imager. The image processor is configured to compute a convergence matrix and a noise threshold matrix, to estimate background information of an image utilizing the convergence matrix, and to eliminate at least a portion of the background information from the image utilizing the noise threshold matrix. The background estimation and elimination may involve the generation of static and dynamic background masks that include elements indicating which pixels of the image are part of respective static and dynamic background information. The computing, estimating and eliminating operations may be performed over a sequence of depth images, such as frames of a 3D video signal, with the convergence and noise threshold matrices being recomputed for each of at least a subset of the depth images.

摘要： In one embodiment, the invention is a method for performing preamble detection in a wireless communication network. The method performs a first dwell, wherein non-overlapping chunks of received data are processed to generate partial correlation values for each possible combination of a signature code and delay. Candidate selection is performed by comparing each of the partial correlation values to a candidate-selection threshold. For each detected candidate, the chunks of received data are processed to generate full correlation values. Each full correlation value is then compared to a preamble-detection threshold to detect a transmitted signature. Generating full correlation values for only the selected candidates reduces the computation complexity over prior-art methods that generate full correlation values for all signatures at all delays.
