    摘要: A method for automatically setting a rendering parameter for a virtual endoscope for rendering images for virtual endoscopy, comprises deriving a data set corresponding to an inside view of a viewing frustum of the endoscope; calculating a histogram from the data set; correlating features of the histogram with known physical regions wherein the endoscope is situated; and selecting a transfer function positioned relative to the features of the histogram for providing image differentiation between respective rendered images of the physical regions in the images.
