Mesoporous titania powders: the role of precursors, ligand addition and calcination rate on their morphology, crystalline structure and photocatalytic activity / Masolo, Elisabetta ; Meloni, Manuela ; Garroni, Sebastiano ; Mulas, Gabriele ; Enzo, Stefano ; Baró, M. D. ; Rossinyol, Emma ; Rzeszutek, Agnieszka ; Herrmann-Geppert, Iris ; Maria Pilo, Maria
We evaluate the influence of the use of different titania precursors, calcination rate, and ligand addition on the morphology, texture and phase content of synthesized mesoporous titania samples, parameters which, in turn, can play a key role in titania photocatalytic performances. [...]

Moving cast shadow detection / Amato, Ariel
Motion perception is an amazing innate ability of the creatures on the planet. This adroitness entails a functional advantage that enables species to compete better in the wild. The motion perception ability is usually employed at different levels, allowing from the simplest interaction with the ’physis’ up to the most transcendental survival tasks. [...]

Exploiting multimedia content : a machine learning based approach / Hassa, Ehtesham
This thesis explores use of machine learning for multimedia content management involving single/multiple features, modalities and concepts. We introduce shape based feature for binary patterns and apply it for recognition and retrieval application in single and multiple feature based architecture. [...]

Colour constancy in natural images through colour naming and sensor sharpening / Vázquez Corral, Javier
Colour is derived from three physical properties: incident light, object reflectance and sensor sensitivities. Incident light varies under natural conditions; hence, recovering scene illuminant is an important issue in computational colour. [...]

Algorithms for selecting parameters of combination of acyclic adjacency graphs in the problem of texture image processing / Viet Sang, Dinh
Nowadays the great interest of researchers in the problem of processing the interrelated data arrays including images is retained. In the modern theory of machine learning, the problem of image processing is often viewed as a problem in the field of graph models. [...]

Monitoring and diagnosing neonatal seizures by video signal processing / Kouamou Ntonfo, G.M.
In this thesis we consider the use of well-known statistical methods to early diagnose, through wire-free low-cost video processing, the potential presence of seizures. For this purpose several approaches, have been proposed: periodicity-based, classification-based and clustering-based approaches.

Monocular depth cues in computer vision applications / Cheda, Diego
In the computer vision field, if image depth information were available, many tasks could be posed from a different perspective for the sake of higher performance and robustness. In our thesis, we have demonstrated how coarse depth information can be integrated in different tasks following alternative strategies to obtain more precise and robust results in three computer vision applications: camera rotation parameters estimation, background estimation and pedestrian candidate generation.
