The geometrical concept of the Voronoi diagram was used to create an image filter providing a “stained glass” or mosaic effect on an image. The Voronoi diagram was calculated by exploiting its dual relationship with the Delaunay triangulation, which was in turn calculated using a randomized incremental algorithm and stored in a DCEL. Various methods were tried for selecting the points, includin...

I propose to develop an algorithm for generating physically accurate stained glass images. I will study the chemistry and the optics of stained glass and analyze the optical properties of lead. I will implement a physics-based stained glass modeling algorithm and a distributed ray tracer, which will increase the realism. The output software will be able to generate stained glass images from mod...

The main problem of photographing stained glass windows is setting the correct exposure. An overall average exposure setting frequently results in the highlight areas being overexposed, or dark area being under-exposed, or both. It is therefore necessary to provide a suitable set of image processing tools to correct the image defects. In this work describe several algorithms to solve this probl...
