This paper developed an algorithm for rendering high-quality integral videography (IV) images for use in autostereoscopic three-dimensional (3-D) surgical display system. IV is an animated extension of integral photography, which provides 3-D images without having to use any supplementary glasses or tracking devices. Despite IV's many advantages, the quality of its spatial image has thus far been poor. We proposed a high-quality image rendering method with oversampling technique to enhance the resolution of elemental IV image and a low-pass-filter to smooth the image. Testing of the method using a high-resolution IV display and a test pattern showed that the qualities of the anti-aliased IV images were better than that of images rendered using a conventional method. An image-guided surgery display system incorporating the proposed algorithm would enable identification of optimum process for producing high-quality 3-D images for planning of and guidance during minimally invasive surgery.
