  • Publication number: 20170301068
    Abstract: 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.

  • Patent number: 9789608
    Abstract: A synthetic representation of a robot tool for display on a user interface of a robotic system. The synthetic representation may be used to show the position of a view volume of an image capture device with respect to the robot. The synthetic representation may also be used to find a tool that is outside of the field of view, to display range of motion limits for a tool, to remotely communicate information about the robot, and to detect collisions.

  • Patent number: 9775499
    Abstract: An endoscope with an optical channel is held and positioned by a robotic surgical system. A capture unit captures (1) a visible first image at a first time and (2) a visible second image combined with a fluorescence image from the light at a second time. An image processing system receives (1) the visible first image and (2) the visible second image combined with the fluorescence image and generates at least one fluorescence image. A display system outputs an output image including an artificial fluorescence image.

  • Patent number: 9526587
    Abstract: The present disclosure relates to systems, methods, and tools for tool tracking using image-derived data from one or more tool-located reference features. A method includes: capturing a first image of a tool that includes multiple features that define a first marker, where at least one of the features of the first marker includes an identification feature; determining a position for the first marker by processing the first image; determining an identification for the first marker by using the at least one identification feature by processing the first image; and determining a tool state for the tool by using the position and the identification of the first marker.

  • Patent number: 9503713
    Abstract: Stereo gaze tracking estimates a 3-D gaze point by projecting determined right and left eye gaze points on left and right stereo images. The determined right and left eye gaze points are based on one or more tracked eye gaze points, estimates for non-tracked eye gaze points based upon the tracked gaze points and image matching in the left and right stereo images, and confidence scores indicative of the reliability of the tracked gaze points and/or the image matching.

  • Patent number: 9492240
    Abstract: Robotic and/or measurement devices, systems, and methods for telesurgical and other applications employ input devices operatively coupled to tools so as to allow a system user to manipulate tissues and other structures being measured. The system may make use of three dimensional position information from stereoscopic images. Two or more discrete points can be designated in three dimensions so as to provide a cumulative length along a straight or curving structure, an area measurement, a volume measurement, or the like. The discrete points may be identified by a single surgical tool or by distances separating two or more surgical tools, with the user optionally measuring a structure longer than a field of view of the stereoscopic image capture device by walking a pair of tools “hand-over-hand” along the structure.

  • Publication number: 20160279801
    Abstract: A robotic system includes a processor that is programmed to determine and cause work site measurements for user specified points in the work site to be graphically displayed in order to provide geometrically appropriate tool selection assistance to the user. The processor is also programmed to determine an optimal one of a plurality of tools of varying geometries for use at the work site and to cause graphical representations of at least the optimal tool to be displayed along with the work site measurements.

  • Publication number: 20160227129
    Abstract: Mixed mode imaging is implemented using a single-chip image capture sensor with a color filter array. The single-chip image capture sensor captures a frame including a first set of pixel data and a second set of pixel data. The first set of pixel data includes a first combined scene, and the second set of pixel data includes a second combined scene. The first combined scene is a first weighted combination of a fluorescence scene component and a visible scene component due to the leakage of a color filter array. The second combined scene includes a second weighted combination of the fluorescence scene component and the visible scene component. Two display scene components are extracted from the captured pixel data in the frame and presented on a display unit.

  • Patent number: 9402690
    Abstract: An apparatus is configured to show telestration in 3-D to a surgeon in real time. A proctor is shown one side of a stereo image pair, such that the proctor can draw a telestration line on the one side with an input device. Points of interest are identified for matching to the other side of the stereo image pair. In response to the identified points of interest, regions and features are identified and used to match the points of interest to the other side. Regions can be used to match the points of interest. Features of the first image can be matched to the second image and used to match the points of interest to the second image, for example when the confidence scores for the regions are below a threshold value. Constraints can be used to evaluate the matched points of interest, for example by excluding bad points.
