Digital imaging of thin sections is an integral part of contemporary geoscience research. Images taken under the petrographic microscope (i.e., photomicrographs) capture mineralogical and textural features—e.g., modal mineralogy, grain size, and fabrics—that can be quantified and interpreted via digital image analysis. However, it can be challenging to capture all the features present in a full thin section, owing to the limited field of view that is possible on a standard petrographic microscope (∼5 mm). These areas can be imaged under the microscope and stitched together into image mosaics (i.e., image mosaicking), but this is...
