Abstract
A process is operable using a computerized system for grading the clarity of a diamond. The computerized system includes an optical image acquisition device, a processor, a pre-trained neural network and an output module operably interconnected together. The process includes: (i) acquiring via an optical image acquisition device one or more plural axial view images of a diamond with different focus depths; (ii) in a processor, combining the plural axial views to form one or more single optical images; (iii) in a pre-trained neural network, providing a regressive value associated with the clarity grade of the diamond based on the one or more single images acquired during step (i); and (iv) from an output module, providing a clarity grade to the diamond (i) by correlating the regression value from (ii) to a clarity grade.
