Abstract: Objects within two-dimensional video data are modeled by three-dimensional models as a function of object type and motion through manually calibrating a two-dimensional image to the three spatial dimensions of a three-dimensional modeling cube. Calibrated three-dimensional locations of an object in motion in the two-dimensional image field of view of a video data input are determined and used to determine a heading direction of the object as a function of the camera calibration and determined movement between the determined three-dimensional locations. The two-dimensional object image is replaced in the video data input with an object-type three-dimensional polygonal model having a projected bounding box that best matches a bounding box of an image blob, the model oriented in the determined heading direction. The bounding box of the replacing model is then scaled to fit the object image blob bounding box, and rendered with extracted image features.

Abstract: Traffic flow control. A method identifies traffic in an area. The traffic includes traffic objects. The identifying obtains identifiers of traffic objects in the area.

Abstract: A safety light system on an excavator or parked vehicle that is manually operated by the excavator operator. The unit is typically controlled by a single button located in the excavator cab. The excavator operator presses the button. A green LED, or other green light, projects a green beam of light toward the rear of the truck. This signals the truck driver that he can begin backing toward the excavator. At a predetermined distance, the excavator operator again pushes the button. The unit switches to an orange light. Finally, in a final position, the excavator operator again presses the button to project a red light. As the truck driver backs toward the excavator, he first sees green, then orange and finally red. Upon seeing red, he knows to stop backing. A fourth push can again project a green light signaling a safe condition for drive-away.

Abstract: Methods and systems for reducing the required footprint of SNoW-based classifiers via optimization of classifier features. A compression technique involves two training cycles. The first cycle proceeds normally and the classifier weights from this cycle are used to rank the Successive Mean Quantization Transform (SMQT) features using several criteria. The top N (out of 512 features) are then chosen and the training cycle is repeated using only the top N features. It has been found that OCR accuracy is maintained using only 60 out of 512 features leading to an 88% reduction in RAM utilization at runtime. This coupled with a packing of the weights from doubles to single byte integers added a further 8× reduction in RAM footprint or a reduction of 68× over the baseline SNoW method.
