    摘要： An exemplary method includes receiving a frame of raw pixels captured by an image capture sensor, a particular location in the frame of raw pixels including a captured color pixel value of a first color component of a first color space; generating, for the particular location in the frame of raw pixels, a vertical color difference signal and a horizontal color difference signal using information from the frame of raw pixels; determining that the particular location is missing a color pixel value of a second color component of the first color space; generating a reconstructed color pixel value of the second color component based on the vertical color difference signal and the horizontal color difference signal; and transforming the vertical color difference signal and the horizontal color difference signal into chrominance pixel values in a second color space that is different from the first color space.

    摘要： A tool tracking method comprises receiving stereo image data of a tool. The tool includes a tracking marker. The method also comprises receiving first kinematic data for the tool and determining a three-dimensional image-derived pose of the tool from the stereo image data of the tool and the tracking marker. The method also comprises determining a first kinematic pose of the tool from the first kinematic data and determining a pose offset between the image-derived pose of the tool and the first kinematic pose of the tool. The method also comprises determining a corrected first kinematic pose of the tool based on the pose offset and the first kinematic data.

    摘要： 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.
