Automatic grain segmentation in cross-polarized photomicrographs of sedimentary rocks using psychophysics inspired models

The present work analyses the effect of three spatial filters, modelling the psychophysics data on brightness perception, when applied to a difficult computer vision problem. This pertains to the automatic grain-matrix segmentation of cross-polar images of sedimentary rock thin sections, gathered through petrographic microscopy. These three filters are assumed to be modelling three modes of vision, viz. vision-at-a-glance (VG, through...
