This particular photo-masking application is an experiment as we are attempting to model a square bowl and a potter's wheel pivot excavated in Gird-i-Bazar, Kurdish Autonomous Region of Iraq, province of Sulaymaniyah.
This application enables the creation of a high quality 3D model of an archaeological artefact via process known as photo-masking. There has been a revolution in 3D modelling in recent years and it is now relatively easy to construct such models from ordinary digital photographs. Isolating the object depicted in these photographs, and masking out the background, is an important first step to achieving high quality results. The final 3D model will be made publicly available and is useful not only for basic documentation purposes, but also for graphical displays in museums, for inclusion in gaming and virtual reality environments, or for identifying different sub-styles in otherwise similar types of artefact (that might tell us about the date of the artefact, where it was made, or by whom).
This particular photo-masking application is about a square bowl and a potter's wheel pivot. Both objects were found in Gird-i Bazar, which is part of an Iron Age settlement complex (ca. 1200-600BCE) located in the Kurdish Autonomous Region of Iraq, province of Sulaymaniyah. The objects were excavated in Autumn 2017 during archaeological investigations carried out by LMU Munich's Ancient History Department, which has been running the excavation since 2015.
According to excavators, the square bowl served as a basis for the wheel pivot which was placed on it. On the pivot, a wooden wheel was rotated, on which the clay was fashioned into a pot. This mechanism is known as a potter's slow-wheel. With this crowd-sourcing project, we are asking for your help to assist with the 3D documentation of one of these tools.
We would like people to draw a polygon around the object that they see in each photograph in order to identify its outline and exclude the image background. This allows the 3D modelling process to concentrate on the object itself and ignore irrelevant background information.
