Abstract
This paper presents a method for integrating synthetic objects in real-world photographs. We take a set of pho-
tographs of a real scene and build a simple image-based model. We use high dynamic range images to build an
accurate representation of the lighting in the scene. Then we insert a synthetic object into the model and compute
its illumination and shading using the lighting information. Illumination changes produced by the synthetic object
are also applied to the background plane in the real-world photograph. We show how easy it is to achieve photo-
realistic results without specialized hardware. Our approach takes advantage of techniques like automatic camera
calibration, high-dynamic range image capture and image-based lighting.
We show preliminary results obtained with our application. We also present two improvements that we are cur-
rently studying. They are aimed at improving the quality of the resulting images and decreasing the computational
resources needed by the process.
Categories and Subject Descriptors (according to ACM CCS): I.3.3 [Computer Graphics]: Display algorithms I.3.7
