Annual Reports

• 2005.
My intent in this first year was to enrich my background knowledge in restoration imaging and in 3D fluorescence microscopy. I studied the mathematical model of image formation in 3D fluorescence microscopy (Wide-Field, Confocal and Two-Photon-Excitation microscopy) and I started one preliminary work concerning the study of statistical approach algorithms. In particular I used the C language to implement the image formation model and the Expectation-Maximizzation (EM) alghoritm. During my first year I collaborated with Prof. Alberto Diaspro (LAMBS).

• 2006.
The second year of my PhD has been devoted to the study of maximum a-posteriori image restoration approach to 3D confocal microscopy. This approach has the potential advantage of incorporation of prior knowledge in the reconstruction process through the prior function. The image field is suitably modeled as a Markov random field resulting in a Gibbs distribution for the prior function. This allows to model characteristics of an object, such as local smoothness or edge, in terms of potential functions. A fuzzy-logic-based potential is employed in the Gibbs prior. Unlike other potentials, the fuzzy potential distinguishes intensity variation due to genuine edges and noise. The proposed approach has generated artifact-free restored confocal microscopy images. Also During this second year I collaborated with Prof. Alberto Diaspro (LAMBS).

• 2007.
In the third year of my PhD I continued to explore the combination of Markov random field (MRF) and maximum a-posteriori approach for the solution of the regularized 3D fluorescence microscopy image restoration problem. A new wide class of non-quadratic potential functions, specially designed for edge-preserving image restoration, are studied and tested both on simulated and on real data-sets. Moreover, a new general approach, called split gradient method (SGM), is extended to the 3D fluorescence microscopy case, and integrated with the MRF approach to produce suitable iterative methods for the solution of the regularized image restoration problem. Also during this third year I collaborated with Prof. Alberto Diaspro (LAMBS).
