A knowledge based architecture for the virtual restoration of ancient photos
2017
Abstract Historical images are essential documents of the recent past. Nevertheless, time and bad preservation corrupt their physical supports. Digitization can be the solution to extend their “lives”, and digital techniques can be used to recover lost information. This task is often difficult and time-consuming, if commercial restoration tools are used for the purpose. A new solution is proposed to help non-expert users in restoring their damaged photos. First, we defined a dual taxonomy for the defects in printed and digitized photos. We represented our restoration domain with an ontology and we created some rules to suggest actions to perform in case of some specific events. Classes and …
Filling-in Gaps in Textured Images Using Bit-Plane Statistics
2008
In this paper we propose a novel approach for the texture analysis-synthesis problem, with the purpose to restore missing zones in greyscale images. Bit-plane decomposition is used, and a dictionary is build with bit-blocks statistics for each plane. Gaps are reconstructed with a conditional stochastic process, to propagate texture global features into the damaged area, using information stored in the dictionary. Our restoration method is simple, easy and fast, with very good results for a large set of textured images. Results are compared with a state-of-the-art restoration algorithm.

Restoration of Digitized Damaged Photos using Bit-Plane Slicing
2007
Digital image restoration aims to recover damaged zones of a digital image, using surrounding information. In this paper we propose a novel approach, based on bit-plane slicing decomposition, with the purpose to make information analysis and reconstruction process easy, fast and effective. Tests have been made on digitized damaged old photos to restore several classes of typical defects in old photographic prints.
Texture Synthesis for Digital Restoration in the Bit-Plane Representation
2007
In this paper we propose a new approach to handle the problem of restoration of grayscale textured images. The purpose is to recovery missing data of a damaged area. The key point is to decompose an image in its bit-planes, and to process bits rather than pixels. We propose two texture synthesis methods for restoration. The first one is a random generation process, based on the conditional probability of bits in the bit-planes. It is designed for images with stochastic textures. The second one is a best-matching method, running on each bit-plane, that is well suited to synthesize periodic patterns. Results are compared with a state-of-the-art restoration algorithm.
Restoration of out of focus images based on circle of confusion estimates
2002
In this paper a new method for a fast out-of-focus blur estimation and restoration is proposed. It is suitable for CFA (Color Filter Array) images acquired by typical CCD/CMOS sensor. The method is based on the analysis of a single image and consists of two steps: 1) out-of-focus blur estimation via Bayer pattern analysis; 2) image restoration. Blur estimation is based on a block-wise edge detection technique. This edge detection is carried out on the green pixels of the CFA sensor image also called Bayer pattern. Once the blur level has been estimated the image is restored through the application of a new inverse filtering technique. This algorithm gives sharp images reducing ringing and c…
La giustizia riparativa: i nuovi e molteplici incroci con il rito penale
2023
The "organic discipline" of restorative justice represents one of the most significant innovations introduced by the "Cartabia reform" (L. Nr. 134/2021; D.Lgs. Nr. 150/2022). Many norms will require an interpretative effort in the context of the case-law. Among the most debated points emerge, in particular, those concerning the confidentiality of the reparative programs, the complaint and its withdrawal, as well as respect for the presumption of innocence and the impartiality of the judge. La "disciplina organica" della giustizia riparativa rappresenta una tra le più significative novità introdotte dalla "riforma Cartabia" (L. n. 134/2021, D.lgs. n. 150/2022). Molti profili richiederanno un…
Nuove prospettive per la Restorative Justice in seguito alla Direttiva sulla vittima: verso un “diritto alla mediazione”? Germania e Italia a confron…
2015
Gli strumenti di "restorative justice" sono stati recentemente oggetto di attenzione da parte del legislatore dell'Unione europea, soprattutto mediante la Direttiva 2012/29/UE. Quest'ultima sollecita un'evoluzione dei diversi sistemi nazionali che inevitabilmente tende verso obiettivi variabili, a seconda dei modelli conciliativi e mediativi attualmente previsti. In particolare, in Germania, si mira al riconoscimento di un "diritto di accesso" della vittima alle pratiche mediative e a un loro perfezionamento; in Italia, si punta invece ad un'operatività più diffusa degli istituti di "restorative justice", oggi ancora limitati a pochi ambiti, e ad una maggiore tutela delle garanzie individua…
