1. A method, comprising:
calibrating, via an analysis and control system, one or more photographs that depict a plurality of cuttings;
identifying, via the analysis and control system, one or more individual cuttings of the plurality of cuttings depicted in the one or more calibrated photographs;
extracting, via the analysis and control system, morphological, color, texture, grain size, and grain distribution data from each individual cutting of the one or more individual cuttings;
performing, via the analysis and control system, lithological classification of the one or more individual cuttings at a plurality of hierarchical levels based at least in part on the extracted morphological, color, texture, grain size, and grain distribution data; and
presenting, via the analysis and control system, a consolidated results summary of the lithological classification of the one or more individual cuttings at the plurality of hierarchical levels via the analysis and control system.
