Integration of 3D modelling with photogrammetry applied on historical images for cultural heritage
2023
The recovery of past architecture through 3D modelling is an important challenge today to the preservation of heritage. Decisive support for the interpretation of architecture can certainly come from historical images and old photographs that fix a portion of space at a specific time, keeping it unchanged over the years. This acquisition is decisive for studying architectures of the past that can be reinterpreted and analysed. Photos, in fact, capture the advance of time and the life of a building at a precise historical moment, becoming essential documents for the study and knowledge of heritage. An additional advantage is when these old images can be processed through Structure for Motion…
La digitalizzazione del patrimonio come strumento per la conoscenza, un’esperienza sull’architettura ferroviaria siciliana
2022
The process of digitisation of the artistic and cultural heritage has enriched the possibilities of representation and communication of architecture, increasing the modes of reproduction, fruition as well as the possibilities of protection and preservation. The study of this research draws attention on the continuous progress of technology in the cultural field and highlights the important collaboration that exists between digital and analog representation, identifying, with this synergy, a virtuous path that allows, through the use of different methodologies, to be able to know and analyze the historical phases of a building. In particular, the attention was directed to the Caltanissetta C…
A Set of Low-Level Descriptors for Images Affected by Foxing
2008
Old printed photos are affected by several typical damages, due to age and bad preservation. “Foxing” defects look like red-brownish spots onto the paper of the printed photo. Similar features can be seen in the digitized copies. In this paper we propose a set of low level descriptors to extract features from digitized photos affected by foxing. An image retrieval application, based on information extracted by the proposed descriptors, is developed to discriminate, through comparison, if an image is affected by foxing. Results are compared to those obtained using some standard color descriptors.
