Abstract :
[en] Abstract. A new method for automatic counting of etched fission tracks in minerals is
described and presented in this article. Artificial intelligence techniques
such as deep neural networks and computer vision were trained to detect
fission surface semi-tracks on images. The deep neural networks can be used
in an open-source computer program for semi-automated fission track dating
called “AI-Track-tive”. Our custom-trained deep neural networks use the YOLOv3
object detection algorithm, which is currently one of the most powerful and
fastest object recognition algorithms. The developed program successfully
finds most of the fission tracks in the microscope images; however, the user
still needs to supervise the automatic counting. The presented deep neural
networks have high precision for apatite (97 %) and mica (98 %). Recall
values are lower for apatite (86 %) than for mica (91 %). The
application can be used online at https://ai-track-tive.ugent.be (last access: 29 June 2021), or it can be downloaded as an offline application
for Windows.
