Digital Refocusing for Wide-Angle Images Using Axial-Cone Cameras

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

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.

End-to-end design of electro-optic imaging systems for color-correlated objects

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.

Method of forming grating microstructures by anodic oxidation

A method of manufacturing an element having a microstructure of an excellent grating groove pattern or the like is obtained. This method of manufacturing an element having a microstructure comprises steps of forming a metal layer on a substrate, forming a dot column of concave portions on the surface of the metal layer and anodically oxidizing the surface of the metal layer formed with the dot column of concave portions while opposing this surface to a cathode surface thereby forming a metal oxide film having a grating groove pattern. When the interval between the concave portions of the dot column is reduced, therefore, a linear grating groove pattern having a large depth with a uniform groove width along the depth direction is easily formed in a self-organized manner.
