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.
. Strategie e iniziative per il recupero e la valorizzazione: un bilancio sui centri storici siciliani
2020
The present contribution focuses on the strategies carried out to hinder depopulation and facilitate the recovery of the historical city centres in Sicily in the last fifty years. In particular, the essay analyses if the strategies and initiatives fostered in this field had been respectful of the physical characteristics of these small towns. Furthermore, the present study intends to assess if the improvement of the “quality of life” has been considered among the strategies carried out to contrast depopulation. The scarce efficacy of policies and strategies over the last fifty years, which emerges from this analysis, is partially due to the endemic inability of politicians and local communi…
