  • Patent number: 9895230
    Abstract: A method for generating a patient-specific prosthetic implant is disclosed which includes generating, using one or more processors from a medical image of a human anatomical feature, a three dimensional electronic representation of the human anatomical feature including size and surface curvature features matching the human anatomical feature, the surface curvature features including one or more radii of curvature on an outer camming surface of the human anatomical feature. A prosthetic implant template is selected, using the one or more processors, from a database of prosthetic implant templates, and the custom implant is virtually designed to imitate the size and surface curvature features of the three dimensional electronic representation based on the selected prosthetic implant template. Fit of the custom implant is tested, virtually using the one or more processors, using the three dimensional electronic representation of the human anatomical feature.

  • Patent number: 9892317
    Abstract: Extracting financial card information with relaxed alignment comprises a method to receive an image of a card, determine one or more edge finder zones in locations of the image, and identify lines in the one or more edge finder zones. The method further identifies one or more quadrilaterals formed by intersections of extrapolations of the identified lines, determines an aspect ratio of the one or more quadrilateral, and compares the determined aspect ratios of the quadrilateral to an expected aspect ratio. The method then identifies a quadrilateral that matches the expected aspect ratio and performs an optical character recognition algorithm on the rectified model. A similar method is performed on multiple cards in an image. The results of the analysis of each of the cards are compared to improve accuracy of the data.

  • Patent number: 9813597
    Abstract: The present disclosure provides a gaze tracker and a gaze tracking method. The gaze tracker includes: an image acquirer to acquire eye images of a user using two or more cameras and two or more lightings; and a gaze calculator which detects a lighting reflection point from each eye image to extract a cornea central point, detects a pupil central point from each eye image, and calculates a gaze vector. In particular, when lighting reflection points are detected from each eye image, the gaze calculator calculates vectors for connection between each lighting and a corresponding lighting reflection point and detects an intersection point between the calculated vectors. When only one lighting reflection point is detected, the gaze calculator extracts the cornea central point using distance information between a pre-stored lighting reflection point and the cornea central point and the one lighting reflection point.
