摘要： In one embodiment of the invention, an apparatus is disclosed including an image sensor, a color filter array, and an image processor. The image sensor has an active area with a matrix of camera pixels. The color filter array is in optical alignment over the matrix of the camera pixels. The color filter array assigns alternating single colors to each camera pixel. The image processor receives the camera pixels and includes a correlation detector to detect spatial correlation of color information between pairs of colors in the pixel data captured by the camera pixels. The correlation detector further controls demosaicing of the camera pixels into full color pixels with improved resolution. The apparatus may further include demosaicing logic to demosaic the camera pixels into the full color pixels with improved resolution in response to the spatial correlation of the color information between pairs of colors.

摘要： Provided are a system and method for image sharpening is provided that involves capturing an image, and then decomposing the image into a plurality of image-representation components, such as RGB components for example. Each image-representation component is transformed to obtain an unsharpened multi-resolution representation for each image-representation component. A multi-resolution representation includes a plurality of transformation level representations. Sharpness information is transported from an unsharpened transformation level representation of a first one of the image-representation components to a transformation level representation of an unsharpened multi-resolution representation of a second one of the image-representation components to create a sharpened multi-resolution representation of the second one of the image-representation components. The sharpened multi-resolution representation of the second one of the image-representation components is then transformed to obtain a sharpened image. The improved and sharpened image may then be displayed.

摘要： A robotic surgical system positions and holds an endoscope. A visible imaging system is coupled to the endoscope. The visible imaging system captures a visible image of tissue. An alternate imaging system is also coupled to the endoscope. The alternate imaging system captures a fluorescence image of at least a portion of the tissue. A stereoscopic video display system is coupled to the visible imaging system and to the alternate imaging system. The stereoscopic video display system outputs a real-time stereoscopic image comprising a three-dimensional presentation of a blend of a fluorescence image associated with the captured fluorescence image, and the visible image.

摘要： Apparatus and methods for performing satellite proximity operations such as inspection, recovery and life extension of a target satellite through operation of a “Satellite Inspection Recovery and Extension” (“SIRE”) spacecraft which can be operated in the following modes (teleoperated, automatic, and autonomous). The SIRE concept further consists of those methods and techniques used to perform certain (on-orbit) operations including, but not limited to, the inspection, servicing, recovery, and lifetime extension of satellites, spacecraft, space systems, space platforms, and other vehicles and objects in space, collectively defined as “target satellites”. The three basic types of SIRE proximity missions are defined as “Lifetime Extension”, “Recovery”, and “Utility”. A remote cockpit system is provided to permit human control of the SIRE spacecraft during proximity operations.

摘要： A first image of the eye is generated when the cornea of the eye is exposed to a gas. The cornea is covered with an optic of a patient interface. A second image of the eye with the patient interface over the cornea is generated. In this second image, the patient interface distorts the second image of the eye. One or more of a position or an orientation of the eye is determined in response to the first image and the second image when the patient interface has been placed over the cornea.
