Global Color Composition for Curved Screen Display System

Abstract

We present a novel approach called Global Color Composition (GCC) to improve the visual effect of large image show on curved screen multi-projector display system. Instead of traditional approach only blend overlapped area, our algorithm utilize the global gradient-domain information to get better effect, and as an optimizing of the algorithm to reduced time and memory, we utilize the patches border pixels to construct the passion equation. The solver of this passion equation is result image we desired, which can be solving on parallel GPU threads. Experiment results are given to illustrate the effect of our approach.
