Artificial mosaics
@article{Blasi2005ArtificialM, title={Artificial mosaics}, author={Gianpiero di Blasi and Giovanni Gallo}, journal={The Visual Computer}, year={2005}, volume={21}, pages={373-383} }
Art often provides valuable insight that can be applied to technological innovations, especially in the fields of image processing and computer graphics. In this paper we present a method to transform a raster input image into a good-quality mosaic: an “artificial mosaic.” The creation of mosaics of artistic quality is challenging because the tiles that compose a mosaic, typically small polygons, must be packed tightly and yet must follow and emphasize orientations chosen by the artist. The…

Mosaic Animations from Video Inputs
- Computer SciencePSIVT
- 2007
A method for generating mosaic animations from input videos that uses a combination of a segmentation algorithm and an optical flow method to enforce temporal coherence in the mosaic videos, thus avoiding that the tiles move back and forth the canvas, a problem known as swimming.
