  • Patent number: 8233741
    Abstract: A method for reducing building lean in stitched images includes accessing overlapping images of a geographic area, and calculating a pixel preference cost for each pixel region of a plurality of pixel regions in each image based on a location of the respective pixel region in a three-dimensional projection of each image. The method also includes selecting a pixel region from the images for each of a plurality of pixel region positions in the geographic area by reducing a cost function that includes the pixel preference cost, and assigning the respective selected pixel region to each of the pixel region positions to create the stitched image containing the building with reduced lean. In another embodiment, the pixel preference cost includes a distance from center cost that is based on a distance to the respective pixel region from the center of the image. Corresponding systems and computer readable media are also disclosed.

  • Patent number: 5544282
    Abstract: Method and apparatus for automatically planning motions of robot manipulators. The invention rapidly finds a collision-free path in a cluttered robot environment, if one exists, from any starting configuration of the robot manipulator to any ending configuration. The time to solution of a motion planning problem is not uniform, but proportional to the complexity of the problem.
