Enhanced stereographic x-ray images.
This project extends previous work on stereographic projection of 2D x-ray images and aims to overcome a number of problems, namely: confusing stereo cues; distortion between stereo pairs; and increased radiation exposure from additional x-ray images. Images are distortion corrected and a polygonal representation of a bone fitted to the x-ray image, to approximate the bone surface. The polygonal representation is rendered and blended with the x-ray image to add surface detail, without obscuring salient features within the original x-ray. A reduction in x-ray exposure by using a stereo pair of computer-generated polygonal bone images blended with a mono x-ray image is investigated. An experiment provides evidence that depth perception is increased with the inclusion of bone surface rendering, and is achievable with a mono x-ray image.
