Summary

In computer graphics, compositing defines as a technique for merging multiple visual elements to generate a single image. The basic principle of compositing is the separation of visual elements, which can be expected to generate new images by merging visual elements from different scenes. On the other hand, merging separated visual elements may lead to lose visual coherence.

Global illumination (GI) effect is one of the most important factors to enhance photo-realism. GI effect refers to the illumination effect caused by inter-reflection, scattering, refraction, and so on, and it strongly affects visual coherence. Since GI effect is caused by the interaction between the visual elements, it is generally known to be difficult to reproduce it while compositing.

The purpose of this theme is that to reproduce GI effect in digital image compositing. And, we expect that the technique will be applied to high-presence video/AR (Augmented Reality) content.
