Francesco Petrarca, the mocap experiment in Blender

This post is related with the Wikipedia editathon we are organizing for the open source exhibition "Imago Animi", a project derived from the previous experience of "Facce. I molti volti della storia umana".

This time I will write about the experiment in facial MoCap we performed with the 3D model of the FFR (Forensic Facial Reconstruction) of Francesco Petrarca. The poet was indeed one of the five historical personalities connected with the city of Padua, who were the protagonist of a specific session within the exhibition "Facce". Moreover Petrarch is also present in "Imago Animi", due to the fact that its mortal remains were studied by the scientist Giovanni Canestrini, born in Revò, a town very close to Cles (Trentino - Italy), where the exhibition is currently open to visitors.

The image below (Creative Commons Attribution 4.0 International License) is the result of the Forensic facial Reconstruction of Francesco Petrarca, performed starting from the cast of the skull, found in 2005 in the "fondo Canestrini" at the University of Padua.

The FFR portrait of Francesco Petrarca

This cast is the only data available for the FFR, because, as the 2013 recognition on the mortal remains revealed, the skeleton of Petrarch is currently buried with a female skull, dated (with the C14 techniques) between 1134 and 1280 (almost one century before the life of the poet). The aDNA analysis performed in 2004 by Prof. David Caramelli (University of Florence) confirmed this thesis (the skeleton had a male DNA, while the skull a female DNA) [1].

In 2015 Arc-Team has been commissioned to perform the Forensic Facial reconstruction of Petrarca and other historical personalities, in order to prepare the open exhibition "Facce". The work started with the 3D documentation of the cast of the "fondo Canestrini", done (with SfM techiques) by Luca Bezzi (Arc-Team). The cast was previously validated by Dott. Nicola Carrara (of the Anthropological Museum of the Univesrity of Padua), with osteometric measurements based on the drawing published by Giovanni Canestrini on his study about the mortal remains of the poet [2]. Cicero Moraes, the forensic specialist of Arc-Team, later performed the FFR in Blender, with the techniques developed during the years starting from this first post in ATOR: Forensic Facial Reconstruction with Free Software.

Once achieved the final 3D model, we decided to test Blender potentialities in facial MoCap, starting from previous experiences. In this case the idea was a short video in which Francesco Petrarca would have "reciting" one of its poetry and, in particular, the proemial sonnet of the Canzioniere ("Voi ch'ascoltate in rime sparse il sono...").

The video below shows the final result...

... while this video shows the "making of".

For the two open exibitions ("Facce" and "Imago Animi") has been chosen a combination of the previous videos, in order to show also the technique of facial MoCap. The final product, you can see here below, has been performed by Cicero Moraes (Arc-Team) using the facial MoCap tools of Blender, starting from the original video registered by Luca Bezzi (Arc-Team), with the technical help of Dott.ssa Emma Varotto and Dott. Nicola Carrara (Anthropological Museum of the Univesrity of Padua), which recorded the excellent performance of the actor Antonello Pagotto.

This post wants to be also a tribute to all the people involved in the project, for their professionalism and kindness!
Have a nice day!

Arcaheological Forensic Facial Reconstruction with FLOSS

Last week the CAA conference 2015 (Computer Applications and Quantitative Methods in Archaeology) took place in Siena (Italy). It has been a good occasion to meet old friends, share opinions and speak with colleagues from all over the world.

This year Arc-Team participated with three oral presentations and a poster and, of course, we will share these contributions with free licenses (CC-BY) also in ATOR.
Today I upload the poster, which is self-explanatory, thanks to the text added to summarize our experience with Archaeological Forensic Facial Reconstruction (FFR). If you are a regular reader of ATOR, there will be few news for you about our work, but you will find some extra contents which we had not yet time to share through our blog (e.g. a gallery of some of the reconstructions for the open source exhibition "Facce. I molti volti della storia umana"; the video of the FFR of St. Anthony, presented during the "Giugno Antoniano", or the Mocap experiment with Franceso Petrarca).

Here is the poster, I hope you will find it useful:

Have a nice day!

Antrocom NPO patronises the exhibit "FACES. The Many Visages of Human History"

Antrocom nonprofit organization patronises the exhibit FACES. The Many Visages of Human History, which is held in the exhibition halls of the University Centre for Museums in Padua from February 14 to June 14, 2015.

The exhibition is the natural continuation of the Taung Project that, among other activities, also produced the reconstruction of the face of Saint Anthony, which has had great resonance among national and international media.

The faces tell our identity and our history: a personal story, but also the evolutionary history of our species. The face is anatomy, physics, physiology; but it is also a symbol, culture and interpretation.

The aim of the exhibition is to tell the various meanings that a face has and can acquire, thanks to finds and three-dimensional reconstructions of great visual impact. The scientific direction and supervision of the exposure are committed to Telmo Pievani and Nicola Carrara, while the three-dimensional and technological fulfilments are entrusted to Arc-Team and Cicero Moraes.

It is indeed a very special event that does not stop at mere display of artifacts, but it is a moment of reflection on forensic techniques used for the reconstruction of the face and on their scientific methodology. A moment that takes advantage of the most modern information technologies of modelling and sculptural development, with tests based on tomographies and original casts.

The exhibition seeks to reflect on the problems of management, usability and preservation of artifacts, especially if they are very fragile as the finds of biological origin.

Another peculiarity of the exhibition "FACES" is the will of the organizers to spread the potentialities offered by the open source world: not only using softwares with this kind of license, but by sharing the obtained three-dimensional models in an open and transparent way, with the opportunity to improve the realized work by other researchers scattered in different countries.

The exhibition is organized into five main themes:

1 - Let's face the human diversity: our origins through the casts of the main hominin fossils and their facial reconstructions, recreated with special forensic softwares and presented through augmented reality technologies. The exhibit also will present newly discovered species (Ardipithecus, Australopithecus sediba, Homo floresiensis) and, for the first time ever, the facial reconstructions of early hominins came out of Africa about 1.8 million years ago, discovered in Dmanisi site in Georgia (Homo georgicus).
The list of hominins on display:

• Sahelanthropus
• Ardipithecus ramidus
• Kenyanthropus platyops
• Australopithecus afarensis
• Australopithecus africanus (Mrs. Pless and Taung child)
• Australopithecus robustus (Paranthropus robustus)
• Paranthropus boisei
• Australopithecus sediba
• Homo habilis
• Homo ergaster (Turkana boy)
• Homo erectus (H. pekinensis)
• Homo neanderthalensis
• Homo rhodesiensis (H. heidelbergensis)
• Homo heidelbergensis (Bodo)
• Homo floresiensis
• Homo sapiens (Cro-Magnon)
• Homo sapiens (Idautu)
• Homo georgicus 1 (classic cast, Zvedza)
• Homo georgicus 2 (old)
• Homo georgicus 3 (Mzia)
• Homo georgicus 5 (2005)

2 - One face, one race? Not really: the concept of "human race" is scientifically inconsistent. For example, the difference in DNA between an African pygmy and a European is only slightly higher than that the one we can observe between two pygmies or between two Europeans: we are all relatives and all different. Humanity is one!

3 - Faces from the past: five faces emerge from time. Five faces linked to, in different ways, the city of Padua. The oldest one belongs to an Egyptian priest of the Ptolemaic Period, whose mummy is preserved at the Museum of Anthropology. After the anticipation of June 10, 2014, the exhibit will propose again the reconstruction of the face of St. Anthony, along with the one of  Blessed Luca Belludi. The exhibition will give to the face of Francesco Petrarca, reconstructed for the first time, a voice to read the sonnet that opens the Canzoniere. The face of Giambattista Morgagni introduces the figure of another illustrious Paduan citizen, considered the father of contemporary pathological anatomy.

4 - The face as a mirror: famous people have dealt with physiognomy and phrenology: for a long time - as many popular sayings declare - it was considered that the moral qualities of a person were reflected in the external appearance, particularly in the visage. Removing the tinsels of old theories, the scientific study of the faces is continued over time because, undeniably, the face says a lot about us and our history, from both a personal and species point of view.

5 - From the face to the mask: the symbolic visage: covering the face is a gesture that distinguishes us from other animals. This is not a refined technique of mimicry because, although masked, we interact with others: the masks are rather fascinating symbolic territories. The masks on display are the most significant of the Museum of Anthropology, coming from different ethnographic collections around the world. Further, the contribution from the precious collaboration with the "Amleto and Donato Sartori" International Museum of the Mask at Abano Terme (Padua) enriches the section.
