Realizing Pseudo Color Bleeding with a Deep Composite Image

Compositing two or more digital images without causing viewer discomfort is a difficult task. In this study, we focus on the emerging technology named "Deep Compositing," to consider a method for realizing consistent global illumination effects, such as color bleeding, soft shadows, and caustics within such a framework. In this poster paper, we regard the first onset of each deep pixel sample point as a virtual point light and attempt to realize pseudo color bleeding.

I. Introduction

The principal concept of digital image compositing [1] is “separation.” Separating a scene into several elements makes it possible to render them concurrently and re-render them selectively, constructing a large photorealistic cyberworld efficiently. Figure 1:

Pseudo color bleeding. Elements 1-3 are scene elements rendered separately. Deep compositing allows us to perform compositing on these separately rendered scene elements in a correct positional relationship. In addition, the proposed method provides the effect of pseudo color bleeding with a deep composite image.
