Abstract
Digital image processing a digital image of sample drill cuttings retrieved from a geological formation and related methods include identifying individual zones in the image that depict at least a predetermined minimum heterogeneity of a first physical property, extracting particles in each identified zone that depict a second physical property within a predetermined quantitative range, and measuring a third physical property of each extracted particle. The first physical property may be texture, size, color, or spectral response within the zone. The second physical property may be brightness, color, contrast, hue, saturation, or wavelet energy. The third physical property may be size or color.
