    Description: Documenting Cultural Heritage through the extraction of 3D measures with photogrammetry is fundamental for the conservation of the memory of the past. However, when the heritage has been lost the only way to recover this information is the use of historical images from archives. The aim of this study is to experiment with new ways to search for architectural heritage in video material and to save the effort of the operator in the archive in terms of efficiency and time. A workflow is proposed to automatically detect lost heritage in film footage using Deep Learning to find suitable images to process with photogrammetry for its 3D virtual reconstruction. The performance of the network was tested on two case studies considering different architectural scenarios, the Tour Saint Jacques which still exists for the tuning of the networks, and Les Halles to test the algorithms on a real case of an architecture which has been destroyed. Despite the poor quantity and low quality of the historical images available for the training of the network, it has been demonstrated that, with few frames, it was possible to reach the same results in terms of performance of a network trained on a large dataset. Moreover, with the introduction of new metrics based on time intervals the measure of the real time saving in terms of human effort was achieved. These findings represent an important innovation in the documentation of destroyed monuments and open new ways to recover information about the past.

    Description: The volume, dedicated to the 44th International Conference of the Italian Union for Drawing, investigates the theme of ‘Transitions’, which particularly effectively represents our time and the current condition of the discipline of Drawing. The term, beyond its generic meaning of an intermediate stage in a process in which a condition changes from one state to another, has always been used in various fields, from music to geophysics. In fact, the disciplines of drawing have always been confronted with themes and issues relating to transitions from one condition to another. The history of representation tells us of transformations, even epochal ones, relating to ‘drawing’, with all that such transitions entail: suffice it to think of the evolution of forms of representation, of instrumental apparatuses, of the mutability of supports, of the analogical-digital transition underway, of the new modes of communication on platforms, of the hypertrophic offer of images also on the net that confirms Guy Debord’s intuitions relating to the new spectacularisation of society. Similarly, representation triggers transitions in the prefiguration and communication of design, the anticipation and foreshadowing of future events.The challenges posed by the digital pose open questions whose scope can only be glimpsed, such as the relationship between drawing and the act of modelling, and the construction of new paradigms of visual language and communication. ‘Transitions’, almost implicitly, points to possible futures, the evolution of technique and the search for new modes of expression; at the same time, however, it can suggest silences and reflections in a process of connection between history, theory, criticism and construction.
