20140044310 | METHOD OF IDENTIFYING AN OBJECT IN A VISUAL SCENE - An image of a visual scene, comprising a plurality of pixels. is acquired and an associated range map is either determined therefrom or separately acquired. Elements of the range map comprise distances from the camera for each pixel of the image. In one aspect, either the image or the range map is processed with a connected-components sieve filter that locates clusters of pixels or elements that are connected to one another along either adjacent rows, columns or diagonally. In another aspect, a cross-range value of range-map element is compared with a down-range-responsive cross-range threshold of a boundary of a collision-possible space and the pixel or element is nulled or ignored if associated with a location that is not in the collision-possible space. The collision-possible space is responsive to an operating condition of a vehicle from which the image is acquired. | 02-13-2014 |
20140037145 | METHOD OF IDENTIFYING AN OBJECT IN A VISUAL SCENE - A profile of an object is extracted from an image of a visual scene and a center of the profile is then determined. A measurement vector is determined comprising a plurality of distances to the profile from the center, at a plurality of angles relative to and through the center. The measurement vector is filtered with a central moving average filter, and then compared with at least one stored vector representative of at least one type of reference object, wherein the central moving average filter is responsive to the type of the at least one type of reference object, responsive to which a determination is made as to whether or not the object corresponds to at least one reference object, so as to provide for identifying the object in the visual scene. | 02-06-2014 |
20120045119 | METHOD OF IDENTIFYING AN OBJECT IN A VISUAL SCENE - A plurality of features determined from at least a portion of an image containing information about an object are processed with an inclusive neural network, and with a plurality of exclusive neural networks, so as to provide a plurality of inclusive probability values representing probabilities that the portion of the image corresponds to at least one of at least two different classes of objects, and for each exclusive neural network, so as to provide first and second exclusive probability values representing probabilities that the portion of the image respectively corresponds. or not. to at least one class of objects. The plurality of inclusive probability values, and the first and second exclusive probability values from each of the exclusive neural networks, provide for identifying whether the portion of the image corresponds, or not, to any of the at least two different classes of objects. | 02-23-2012 |
20090010495 | Vulnerable Road User Protection System - A range map of a visual scene generated by a stereo vision and associate image processing system, and is filtered to remove objects beyond a region of interest and for which a collision is not possible, and to remove an associated road surface. Objects clustered in range bins are separated by segmentation. A composite range map is generated using principle components analysis and processed with a connected components sieve filter. Objects are identified using one or more of a harmonic profile and other features using an object recognition processor using a combination of inclusive, exclusive and harmonic networks to generate a classification metric. | 01-08-2009 |
20090001976 | MAGNETIC CRASH SENSOR - A time-varying signal is applied to at least one coil in magnetic communication with at least a portion of a vehicle susceptible to deformation responsive to a crash. A sense resistor in series with the at least one coil provides for detecting a current therethrough responsive to a voltage thereacross. The current is responsive to a magnetic condition affecting the magnetic field generated by the at least one coil, responsive to the reluctance of a magnetic circuit with which the at least one coil is in magnetic communication, and responsive to associated eddy currents in proximal conductive elements, responsive to the magnetic field generated by the at least one coil. | 01-01-2009 |
