Free open-source tools: Automated petrographic image analysis by supervised and unsupervised machine learning methods. Interesting paper from Azzam, Blaise and Brigaud (2024).
“We present two novel software tools: GrainSight, which utilizes a supervised deep learning model (FastSAM) for automated grain detection and morphological characterization; and PetroSeg, which employs an unsupervised segmentation approach to explore rock properties and calculate porosity.”
