The DHLAB is presenting the Venice Time Machine project and the Replica App at the Terra Data exhibition at Cité des Sciences in Paris. Terra Data is a true immersion in the world of data. It covers all aspects of the infinite world of data from its production, to its collection and to its many different usages.

Venice in 4D

Public enjoying the video of Venice in 4D

At the exhibition, a video allows the public to explore the 4D evolution through centuries of the Rialto district in Venice. The video is produced by analyzing primary and secondary sources (archival documents and literature) and reshapes all the information by repositioning in a HGIS platform (historical geographic coordinate system).

Replica App

With the Replica App the public can explore the Art History thanks to "deep learning" technologies that today revolutionize our reading of images by using the calculation and learning abilities of networks with several hundred million neurons.

Through non-text searches the Replica App detects pattern similarities and recurrences within very large image databases of works of art. In the app the navigation takes place in a fragment of the "morphograph" of the Art History, the network that binds all images according to criteria of similarity.
