20100265799	COMPRESSIVE SENSING SYSTEM AND METHOD FOR BEARING ESTIMATION OF SPARSE SOURCES IN THE ANGLE DOMAIN - Compressive Sensing (CS) is an emerging area which uses a relatively small number of non-traditional samples in the form of randomized projections to reconstruct sparse or com-pressible signals. Direction-of-arrival (DOA) estimation is performed with an array of sensors using CS. Using random projections of the sensor data, along with a full waveform recording on one reference sensor, a sparse angle space scenario can be reconstructed, giving the number of sources and their DOA's. Signal processing algorithms are also developed and described herein for randomly deployable wireless sensor arrays that are severely constrained in communication bandwidth. There is a focus on the acoustic bearing estimation problem and it is shown that when the target bearings are modeled as a sparse vector in the angle space, functions of the low dimensional random projections of the microphone signals can be used to determine multiple source bearings as a solution of an 1]-norm minimization problem.	10-21-2010

20130183408	POLYETHYLENE GLYCOL LACTID COATING ON FRESH EGG - This process is designed to coat fresh chicken eggs with polyethylene glycol-lactide. The process reduces possible microbial content which may be inside fresh eggs while preventing the contamination of the eggs after being laid. It also extends the shelf life while maintaining the quality of the eggs. In addition, the PEG coating lowers the rate of fractures related to the egg shell while being handled, whether that be during storage, when the eggs are transported, or when the eggs are transferred to a market display.	07-18-2013

20140241624	METHOD AND SYSTEM FOR IMAGE PROCESSING - Various aspects of a system and method for image processing may include a computing device having one or more processors. The computing device may be operable to determine luminance values of multiple pixels in a subset of a frame of a two-dimensional image. The computing device may be operable to determine texture values of the multiple pixels in the subset of the frame. The computing device may be operable to identify a subject region and a background region in the frame of the two-dimensional image based on the determined luminance values and the determined texture values of the plurality of pixels.	08-28-2014
20150317519	OBJECT DETECTION AND EXTRACTION FROM IMAGE SEQUENCES - Object detection and extraction is performed from image sequences utilizing circular buffers for both source images and tracking. The detection and extraction process is performed in relation to the previous and current image, and the current and next image, including: alignment, absolute difference, removal of non-overlaps, and contour detection in difference images. An intersection is performed on these two outputs to retain contours of the current image only. Recovery of missing contour information is performed utilizing gradient tracing, followed by morphological dilation. A splitting process is performed if additional objects are found in a bounding box area. A mask image bounded by object contour is created, color attributes assigned, object verification performed and outliers removed. Then untracked objects are removed from the mask and a mask is output for moving objects with rectangular boundary box information.	11-05-2015
20150317520	METHOD AND APPARATUS FOR EXTRACTION OF STATIC SCENE PHOTO FROM SEQUENCE OF IMAGES - An apparatus and method for extracting a static background image from a non-static image sequence or video sequence having at least three spatially overlapping frames is presented. Obscured static background areas are filled, according to the disclosure, with actual content as the background area becomes visible over time as non-static objects move with respect to the background. Consecutive image frames are stored in tracking buffers from which alignment is performed and absolute differences determined. Object contours are found in the difference image and bounding boxes determined as object masks. The background is then filled from areas outside these object masks to arrive at a static background image.	11-05-2015
20150319375	APPARATUS AND METHOD FOR CREATING REAL-TIME MOTION (STROBOSCOPIC) VIDEO FROM A STREAMING VIDEO - Real-time generation of motion (stroboscopic) video is described which utilizes an object tracking process operating on downsized images in a circular buffer. Utilizing object information from the tracking, a background static scene is extracted into which multiple temporally displaced object images are inserted to create a stroboscopic video frame. Due to its low processing overhead, the apparatus and method is particularly well-suited for implementation on portable devices, such as cameras and cellular phones.	11-05-2015

20160140392	METHOD AND SYSTEM FOR PROCESSING VIDEO CONTENT - Various aspects of a method and system to process video content for extraction of moving objects from image sequences of the video content are disclosed herein. In an embodiment, the method includes determination of one or more object contours of one or more moving objects in the video content. A first object bounding box (OBB) that encompasses a first object contour of a first moving object is created based on the determined one or more object contours. A first object mask for the first moving object is generated in a first destination image frame, based on infilling of the first object contour in the created first OBB.	05-19-2016
20160142730	METHOD AND SYSTEM FOR PROCESSING VIDEO CONTENT - Various aspects of a method and system to process video content are disclosed herein. The method includes determination of a first frame identification value associated with a video content. The first frame identification value corresponds to an average color value of a frame of the video content. The method further includes determination of a second frame identification value associated with the video content. The second frame identification value corresponds to a global motion vector (GMV) value of the frame of the video content. The method further includes determination of a first intermediate frame based on one or both of the first frame identification value and the second frame identification value.	05-19-2016
