  • Astigmatic depth from defocus imaging using intermediate images and a merit function map
    Patent number: 9532032
    Abstract: A rangefinder has a depth camera and a computer. The depth camera is positioned to receive electromagnetic energy from a scene. Imaging optics and a sensor in the camera generate an input image based on electromagnetic energy. The computer receives the input image, calculates intermediate images by applying differentiation operators along different axes to the input image, creates a merit function map, and computes a depth map from the merit function map.

  • Image feature analysis
    Patent number: 8144964
    Abstract: A method for localizing hard objects in soft tissue utilizing a computer based system includes receiving ultrasound data from an ultrasound scanner and converting on the computer based system the ultrasound data into a reflectivity image. The method also includes selecting voxels from the reflectivity image that exceed an adaptive threshold, locating disjointed voxel clusters formed by the selected voxels, and outputting to an external processor locations of the voxel clusters that form a desired shape to an external processor.
