Paper published on PLOS ONE

We are pleased to announce that the results of our work on ASEMI have been published on PLOS ONE. This includes a technical description of the tool we developed to automatically perform the laborious process of segmenting the scanned volumes into the various component materials, such as textiles, organic tissues, balm resin, ceramics, and bones. Using the developed software, the human specialist only needs to manually segment a small sample of the volumetric image. This is used to train and automatically optimise a machine learning system, which can then segment the whole volume in a fraction of the time previously required. The accuracy obtained by the ASEMI segmenter approaches the results of off-the-shelf commercial software using deep learning, at a much lower complexity. Following the principles of “Open Innovation, Open Science, Open to the World”, the developed algorithms, data sets, and results have been made freely available to the general public.

First research visit at the ESRF

Two members of the UM team, Johann A. Briffa and Marc Tanti, have recently visited the ESRF in Grenoble, France. During the visit, Johann and Marc received training on manually segmenting high-resolution 3D X-rays of animal mummies, a laborious task to identify and mark the different parts of the mummy. In this case, the objective is to separate the bones, soft tissue, textiles, and other components. Once the various components are labelled, it becomes possible to view the separate components in 3D, allowing archaeologists to study the mummy without damaging it.

The UM contribution to this project involves the development of artificial intelligence algorithms to automate the segmentation process. This would considerably reduce the time it takes to obtain a segmented image, making it possible to analyse more specimens.
