A Stained Glass Image Filter
Medieval stained glass windows are a stylized artform that has not previously been thoroughly treated in the computer graphics literature. In this paper, we present an automated method for transforming an arbitrary image into a stained-glass version of that image. The key issues in designing a stained glass window are the tile boundaries and tile colors. We use erosion and dilation operators to...
متن کاملImage Stained Glass using Voronoi Diagrams
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...
متن کاملCorrecting image defects of stained glass windows
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...
متن کاملE 90 Project Proposal Stained - Glass Graphics Filter
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...
متن کاملShadow removal from image of stained glass windows
Shadows may be formed on stained glass windows by structural bars supporting the leaded panels, or by external protective wire grilles, or by masonry, such as mullions or buttresses, or external objects, such as trees. The eye tends to ‘‘discount’’ such shadow formations when viewing the actual windows even though in the photographic images they are very clearly visible. This article introduces...
