چکیده

In computer graphics, lighting plays an important role in the appearance of a scene. A change in the configuration of light sources can lead to different aesthetics in the final rendered image. Lighting design becomes increasingly complex when using sophisticated global illumination techniques. In this paper, we present a new approach to automatically design the lighting configuration according to the aesthetic goal specified by the user as a set of target parameters. Target parameters are used to set up an objective function which is minimized using an optimization method. The results show that our method can be used to automatically design a lighting configuration that will give to the final image a classic photographic look.

Eecient Color Segmentation under Varying Illumination Conditions

Video-based human body tracking using color segmentation often causes problems due to movements of the object or changes in the global illumination parameters. In this paper the innuence of varying lighting conditions and large object movements in space is measured and analysed. For color segmentation an eecient technique for histogram-classiication is used. Based on the measurement results we ...

Lighting Networks - A New Approach for Designing Lighting Algorithms

In the past, new global illumination algorithms have usually been designed as a single module that was responsible for the simulation of all aspects of illumination in a scene. A recently developed alternative is the design of small and specialized algorithms (lighting operators) together with an infrastructure for creating more complex algorithms by connecting these building blocks – the Light...
