Translucent Material Transfer Based on Single Images

彬彬

1 Introduction

Extraction and re-rendering of real materials give large contributions

to various image-based applications. As one of the key properties

of modeling the appearance of an object, materials mainly

focus on the effects caused by light transportation. Therefore, understanding

the characteristics of a complex material from a single

photograph and transferring it to an object in another image becomes

a very challenging problem.

Khan et al. [2006] present an image-based material editing method

which can produce translucent or transparent materials in place of

the original diffuse objects or re-render the objects with arbitrary

BRDFs in a single high dynamic range photograph. However, the

experiential models in their system sometimes is not convenient to

create very realistic images, using real materials as input should

be considered. Moreover, this approach employs a re-texturing

method instead of simulating the real mechanism of light transport

in translucent material, that will also affect the synthesis quality.

In this paper, we present a novel framework to transfer real translucent

materials such as fruits and flowers between single images. We

define a group of information which can model the attributes during

the extraction and transfer process. Once we extract those information

from both the source and target images, we can easily produce

a realistic photograph of an object with target-like materials and

suitable shading effects in the environment of sources.
