Abstract
This thesis investigates the problem of producing non-photorealistic digital images especially for aesthetic purposes; this research field has not an ``official'' name yet within the larger realm of Computer Science, some people call it Artistic Rendering (AR), [Col04], some others, Computational Aesthetics (CA), [Com06], someone else Non-Photorealistic Rendering (NPR). In this thesis I prefer the term ``Computational Aesthetics'' because I think that this term better explains the ``essence'', the purpose and the aim of this field: to reproduce the aesthetic essence of human arts by mean of computational tools. Specifically, I address the problem of mosaics rendering, proposing novel algorithms for fast mosaics creation starting from real images. In this thesis I present several methods (together with many improvements) to transform a raster input image into good quality mosaics: artificial (or ancient) mosaics, photomosaics and puzzle image mosaics. The main goal of all methods is to produce good results in an acceptable time and without (or with a minimal) user intervention. Examples reported in this thesis show how the right mixture of mathematical and computational tools may lead to impressive aesthetic results.
