Digital Refocusing for Wide-Angle Images Using Axial-Cone Cameras
InactiveUS20110316968A1Low costOverall ease of placementImage enhancementTelevision system detailsVirtual imageVirtual camera
A single camera acquires an input image of a scene as observed in an array of spheres, wherein pixels in the input image corresponding to each sphere form a sphere image. A set of virtual cameras are defined for each sphere on a line joining a center of the sphere and a center of projection of the camera, wherein each virtual camera has a different virtual viewpoint and an associated cone of rays, appearing as a circle of pixels on its virtual image plane. A projective texture mapping of each sphere image is applied to all of the virtual cameras on the virtual image plane to produce a virtual camera image comprising circle of pixels. Each virtual camera image for each sphere is then projected to a refocusing geometry using a refocus viewpoint to produce a wide-angle lightfield view, which are averaged to produce a refocused wide-angle image.

Precise endoscopic planning and visualization
InactiveUS20090156895A1Ensure safetyLarge depthImage enhancementImage analysisThree vesselsPostural orientation
Endoscopic poses are used to indicate the exact location and direction in which a physician must orient the endoscope to sample a region of interest (ROI) in an airway tree or other luminal structure. Using a patient-specific model of the anatomy derived from a 3D MDCT image, poses are chosen to be realizable given the physical characteristics of the endoscope and the relative geometry of the patient's airways and the ROI. To help ensure the safety of the patient, the calculations also account for obstacles such as the aorta and pulmonary arteries, precluding the puncture of these sensitive blood vessels. A real-time visualization system conveys the calculated pose orientation and the quality of any arbitrary bronchoscopic pose orientation. A suggested pose orientation is represented as an icon within a virtual rendering of the patient's airway tree or other structure. The location and orientation of the icon indicates the suggested pose orientation to which the physician should align during the procedure.

InactiveUS20090141140A1Overcome limitationsAdd depthImage enhancementTelevision system detailsImaging processingPerformed Imaging
An electro-optic color imaging system includes an optical subsystem, a detector subsystem and a digital image processing subsystem. The system is used to image a color-correlated object. In the optical subsystem, the image surfaces for different color channels of the object are substantially separated. Thus, one color channel may be in focus while others are out of focus. The detector subsystem is located at a fixed image distance from the optical subsystem and captures the different color channel images of the object. The image processing subsystem estimates the image of the object by combining the captured color channel images based at least in part on an a priori estimate of the correlation between the color channels.
