    摘要： A method, system, and computer program product for detecting objects. Members of a general class of objects are searched for in a number of images. Members of a specific class of objects are searched for in a number of regions in the number of images where the number of regions contains at least a portion of the members of the general class. A member in the members of the specific class is a potential threat to a rotorcraft.

    摘要： Described is a system for registering a viewpoint of an imaging sensor with respect to a geospatial model or map. An image of a scene of a geospatial region comprising an object is received as input. The image of the scene is captured by a sensor having a current sensor state. Observation data related to the object's state is received, wherein the observation data comprises an object behavior of the object given the geospatial region. An estimate of the current sensor state is generated using a probability of an observation from the observation data given the current sensor state x. Finally, the image of the scene is registered with a geospatial model or map based on the estimate of the current sensor state.

    摘要： A method of recognizing features in a 3D environment includes using a sensor that collects a plurality of sensed data points, populating a strip histogram grid having a plurality of strips, each strip having a dx dimension and a dy dimension, by assigning each sensed data point to a strip in the strip histogram grid that has x, y and z dimensions that encompass the spatial coordinate information of the respective assigned sensed data point, and estimating the local ground plane for a strip in the strip histogram grid by using information on each sensed data point assigned to that strip and surrounding strips in the strip histogram grid. Further methods include extracting smooth surfaces, building segmentation, top down segmentation and bottom up segmentation.

    摘要： A method, apparatus, and computer program product for tracking objects. A number of objects is detected in an image to form a number of detected objects. A number of previously identified objects is searched for in the image using a number of signatures for the number of previously identified objects. A number of tracks for the objects is updated using the number of detected objects and a number of reidentified objects. The number of reidentified objects is from searching for the number of previously identified objects.

    摘要： In an embodiment, a grammar-based, cueing method of object recognition is disclosed. The method may include or comprise accessing cells that define a portion of a three-dimensional (3-D) scene, assigning occupation parameters to the cells to define a plurality of occupied cells and at least one vacant cell, and assigning localization parameters to the occupied cells based on the occupation parameters of their respective neighboring cells. The method may further include or comprise characterizing a plurality of the occupied cells as geometric cues based on their respective occupation and localization parameters, and identifying a target geometric shape associated with the geometric cues.

    摘要： An apparatus and method provides application specific multidimensional information to an application running on a user computing device from a plurality of member documents electronically extracted from a library of electronically searchable documents. An information extractor is adapted to extract occurrences of prospective representations of dimensions of application specific multidimensional information and occurrences of non-application specific multidimensional information from the member documents. Also, an encoder is adapted to encode the occurrences of prospective dimensions of application specific and non-application specific multidimensional information contained in member documents. A member document identifier determines document formatting and decides whether to proceed with further processing. An information verification unit optionally verifies the extraction of application specific multidimensional information from the member documents. A database optionally stores and provides access to the application specific multidimensional information, which may for example be scheduled events having dimensions of time, location, identity.
