High quality autostereoscopic surgical display using anti-aliased integral videography imaging

Abstract

This paper presents an autostereoscopic three-dimensional (3-D) surgical display with high quality integral videography (IV) rendering algorithm. IV is an animated extension of integral photography, which provides 3-D images without using any supplementary glasses or tracking devices. Despite IV's many advantages, the quality of its spatial image has thus far been poor. We developed a high quality image rendering method with oversampling technique for enhancing the resolution of elemental IV image and low-pass-filter for smoothing the image. Furthermore, we manufactured a high-resolution IV display for evaluating the feasibility of proposed method. The experimental results show the quality of anti-aliased IV image is improved. We also integrated the developed IV image into image-guided surgery display system. This approach will allow us to acquire the optimum process to produce high quality 3-D image for planning and guidance of minimally invasive surgery. © Springer-Verlag Berlin Heidelberg 2004.
