2-D Filtering based on Visual Resolution for Live-Action Compositing

Abstract

When compositing CG and photographic images, resolution adjustment of the CG images is essential in order to join the two seamlessly. In regular CG production settings, resolution adjustment depends on the sensibility of the operator, which gives rise to variations in the level of live-action compositing. Herein is proposed a technique to simulate resolution characteristics of photographic images by gaussian filtering of CG images using ISO 12233 Resolution measurements Chart. Seamless image synthesis is possible with this technique because the resolutions of the CG and photographic images generally agree.
