Abstract: Systems and methods for calculating coherent bearing that allow one to reduce the number of TCAS antenna elements. In one embodiment, the bearing calculation takes into account signal-to-noise ratio (SNR) difference experienced from top and bottom antennas mounted on a vehicle.

Abstract: A system and method of processing an image including black text data and non-black text data are described. The system and method use a parametric analysis for discrimination of halftones, texts, and photographs. The parametric analysis provides results that track measurable image metrics without the inherent risk of errant decision making during classification. The creation of symbolic representations is intrinsically a classification process that is subject to error. It represents a fundamental departure from fuzzy logic image segmentation. In the parametric analysis, no pattern matching, no auto-correlation, no screening parameter calculation, and no conventional edge detector (such as a high pass filter) are used.

Abstract: The illustrated embodiment processes scanned image data with a resolution of 600 dpi or higher. Image detection algorithms are used to detect the probable presence of halftone image data, large text image data, small text image data and photographic image data. The image detection algorithms are designed specifically for the amount of data contained in an image with a resolution of 600 dpi or greater. Once an image has been analyzed, the illustrated embodiment provides the correspondingly appropriate image process to the scanned image.
