  • Patent number: 9031317
    Abstract: An adequate solution for computer vision applications is arrived at more efficiently and, with more automation, enables users with limited or no special image processing and pattern recognition knowledge to create reliable vision systems for their applications. Computer rendering of CAD models is used to automate the dataset acquisition process and labeling process. In order to speed up the training data preparation while maintaining the data quality, a number of processed samples are generated from one or a few seed images.

  • Patent number: 8786549
    Abstract: A gyroscope-based device uses a probability model to assign probability of the device being in an intended static state to each received sample of gyroscope data. A new drift error compensation offset and new hand jitter factor are computed for each sample of gyroscope data based on the assigned probability. In this manner, the magnitude of the hand jitter factor varies with the probability of the device being in an intended static state.

  • Patent number: 8467596
    Abstract: A pose of an object is estimated from an from an input image and an object pose estimation is then stored by: inputting an image containing an object; creating a binary mask of the input image; extracting a set of singlets from the binary mask of the input image, each singlet representing points in an inner and outer contour of the object in the input image; connecting the set of singlets into a mesh represented as a duplex matrix; comparing two duplex matrices to produce a set of candidate poses; and producing an object pose estimate, and storing the object pose estimate.

  • Patent number: 8450236
    Abstract: A process for making a catalyst having precious metal nanoparticles deposited on a support includes first providing an aqueous dispersion of support particles. A pre-treatment slurry is prepared by mixing the aqueous dispersion of support particles with a water-soluble precious metal precursor and a reducing agent. The pre-treatment slurry is hydrothermally treated at a temperature in the range of from about 40° C. to about 220° C. for a time sufficient to deposit precious metal nanoparticles on the surface of the support particles, the precious metal nanoparticles having an average particle size less about 50 nm.

  • Patent number: 8442348
    Abstract: Disclosed are methods, devices, and computer program products for image noise reduction. In one example embodiment, a method for reducing noise in a digital image includes several acts. First, one or more objects are identified in an input image. Next, the input image or a portion thereof is processed to produce another image, which may be a blurred version of the input image. Finally, one or more objects in the processed image that correspond to the one or more objects identified in the input image are evaluated to determine whether to discard the one or more objects identified in the input image. For example, if an amount of energy preserved in an object after blurring is less than a threshold, the object may be discarded as noise.

  • Patent number: 8437497
    Abstract: Due to an accumulated error from the pair-wise registration, the stitched image may be blurred or have a gap when a loop is encountered. In order to remove the accumulated error, we identify a closed loop where a first image frame overlaps with a second image frame, the second image frame being captured earlier in a scanning sequence than the first image frame; register the first image frame with the second image frame; and apply a global optimization to adjust registration parameters for the plurality of pair-wise registrations of image frames within the closed loop using global constraints.
