HiGrade DPI - A modern tool for placer gold exploration
HiGrade DPI is a novel analysis tool for placer gold that relies on modern image processing to identify gold particles in a high resolution image. Gold particle count, size and shape are instantly presented in a report. Based on that, the calibrated tool calculates the gold content of the sample in g/t or g/m3
Applications
