This paper describes a technique to effectively visualize three-dimensional (3-D) images commonly given as sequences of two-dimensional (2-D) slice images such as microscopic serial section images and multiple CT slices. The method is based on the principle of binocular stereoscopy and the idea of semi-transparent viewing. The main problem addressed here is that of computing a stereo pair directly from a set of 2-D gray-level images. A transmitted-light model is introduced for determining each pixel value in the stereo images. Effectiveness of the method is verified in 3-D view of biomedical section images.
