20120321175 | LOCATION-AIDED RECOGNITION - A mobile device having the capability of performing real-time location recognition with assistance from a server is provided. The approximate geophysical location of the mobile device is uploaded to the server. Based on the mobile device's approximate geophysical location, the server responds by sending the mobile device a message comprising a classifier and a set of feature descriptors. This can occur before an image is captured for visual querying. The classifier and feature descriptors are computed during an offline training stage using techniques to minimize computation at query time. The classifier and feature descriptors are used to perform visual recognition in real-time by performing the classification on the mobile device itself. | 12-20-2012 |

20150356368 | ENTRANCE DETECTION FROM STREET-LEVEL IMAGERY - Architecture that detects entrances on building facades. In a first stage, scene geometry is exploited and the multi-dimensional problem is reduced down to a one-dimensional (1D) problem. Entrance hypotheses are generated by considering pairs of locations along lines exhibiting strong gradients in the transverse direction. In a second stage, a rich set of discriminative image features for entrances is explored according to constructed designs, specifically focusing on properties such as symmetry and color consistency, for example. Classifiers (e.g., random forest) are utilized to perform automatic feature selection and entrance classification. In another stage, a joint model is formulated in three dimensions (3D) for entrances on a given facade, which enables the exploitation of physical constraints between different entrances on the same facade in a systematic manner to prune false positives, and thereby select an optimum set of entrances on a given facade. | 12-10-2015 |

20100014713 | Road-lane marker detection - A method is provided for detecting road lane markers using a light-based sensing device. Reflectivity data is captured using the light-based sensing device. A light intensity signal is generated based on the captured reflectivity data. The light intensity signal is convolved with a differential filter for generating a filter response that identifies a candidate lane marker region and ground segment regions juxtaposed on each side of the candidate lane marker region. A weighted standard deviation of the data points within the identified candidate lane marker region and weighted standard deviation of the data points within the ground segment regions are calculated. An objective value is determined as a function of the respective weighted standard deviations. The objective value is compared to a respective threshold for determining whether the identified candidate lane marker region is a lane marker. | 01-21-2010 |
20100014714 | Camera-based lane marker detection - A method is provided for detecting road lane markers in a vehicle road using an imaging device. Road input data is captured using the imaging device. Lighting normalization is applied to the road input data. The method detects the road lane markers in a few main orientations in the normalized input data. In each main orientation, the normalized input data is convolved with an oriented edge detection filter for generating an oriented edge-based filter response. The normalized input data is convolved with an oriented line detection filter for generating an oriented line-based filter response. Candidate lane markers are selected in response to the edge-based filter response and line-based filter response in each main orientation. A transformation technique is applied to the candidate lane markers for identifying the lane markings in each main orientation. | 01-21-2010 |
20100017060 | Road-edge detection - A method is provided for detecting road-side edges in a road segment using a light-based sensing system. Input range data is captured using the light-based sensing system. An elevation-based road segment is generated based on the captured input range data. The elevation-based road segment is processed by filtering techniques to identify the road segment candidate region and by pattern recognition techniques to determine whether the candidate region is a road segment. The input range data is also projected onto the ground plane for further validation. The line representation of the projected points are identified. The line representation of the candidate regions is compared to a simple road/road-edge model in the top-down view to determine whether the candidate region is a road segment with its edges. The proposed method provides fast processing speeds and reliable detection performance for both road and road-side edges simultaneously in the captured range data. | 01-21-2010 |
20100131197 | VISUAL GUIDANCE FOR VEHICLE NAVIGATION SYSTEM - A system and method that provide a video-based vehicle navigation system. The system positions an arrow on the video display that shows the specific turning direction for the vehicle for route guidance purposes. To determine the proper position of the guidance arrow, the process determines a distance from the current vehicle position to the location where the vehicle needs to turn using any suitable information, such as GPS position, range measurements and map information. The process then positions the guidance arrow on the ground at the turning location in world coordinates, and projects the guidance arrow onto the image. The camera can be calibrated to the ground using various techniques, such as an online automatic calibration process that uses detected objects in the scene around the vehicle. | 05-27-2010 |
