    摘要: A method of decoding a coherent RGB color barcode captured by a RGB camera includes: displaying a coherent RGB color barcode on the RGB display; capturing an image of the displayed barcode; performing a pilot block RGB color interference cancellation process to estimate a per pixel color interference; applying the per pixel color interference to the image of the displayed coherent RGB color barcode to extract each separate barcode of the coherent RGB color barcode; binarizing each of the three separate monochrome grey images of each barcode of the coherent RGB color barcode; and decoding each of the three separate binarized monochrome grey images to provide a decoded data for each barcode of the coherent RGB color barcode displayed on the RGB display. A method of decoding an incoherent RGB color barcode captured by a mobile device RGB camera is also described.

    摘要: Methods for aligning images captured by aerial imaging platforms with a road network described by geo-referenced data, including the steps of: (a) identifying locations of moving vehicles in at least one image; (b) estimating a coordinate transformation that aligns the identified locations with the road network described by the geo-referenced data; and (c) outputting the estimated coordinate transformation or applying the estimated coordinate transformation to at least one image to align the image(s) with the road network described by the geo-referenced data. The methods may classify post-transformation detection as on-road detections or non-on-road detections to improve accuracy and synergistically use transformations and proximity to the road network to improve vehicle detection. The methods may identify vehicle trajectories to further improve accuracy and synergistically use transformations and proximity to the road network to improve estimates of vehicle trajectories.
