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 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...
متن کاملAutomatic Stained Glass Rendering
Based on artistic techniques for the creation of stained glass, we introduce a method to automatically create images in stained glass stylization of images. Our algorithm first applies segmentation, and performs region simplification to merge and simplify the segments. The system then queries a database of glass swatch images and computes an optimal matching subset based on color and texture me...
