US 11,106,648 B2 · Method and system for providing a clarity grade for a gem

Abstract

A method and system for generating a clarity grading look-up table includes collecting actual inclusion parameter data for a plurality of gems, where the actual inclusion parameter data includes an actual clarity grade and an actual inclusion parameter data combination. A mathematical relationship between a clarity grade and a particular inclusion parameter combination is then extrapolated from the actual inclusion parameter data. A derived clarity grade is then assigned to a plurality of inclusion parameter combinations as a function of the mathematical relationship and a set of inputted inclusion parameters. Also, a method and system for providing a clarity grade includes receiving a plurality of inclusion characteristics associated with a gem and parameterizing each of the inclusion characteristics, so that a parameter value is assigned to each inclusion characteristic. The parameter values are then input to a mathematical formula so as to provide a parameterized clarity grade for the gem.

Dependent claims

A non-transitory computer-readable medium including one or more sequences of instructions that, when executed by one or more processors, cause the processors to perform operations comprising:

receiving pixelated image data for a gem, wherein the image data includes an overall gem image and any inclusion within the overall gem image;
mapping any inclusions within the pixelated image data of the gem by counting a number of pixels in the image data of the inclusions;
calculating a size of the overall gem using a number of pixels in the image data of the gem;
parameterizing locations of the mapped inclusions within the pixelated image data of the gem;
determining a relief parameter for each inclusion in the gem using a calculated ratio of an average pixel value within each inclusion to an average pixel value of an area of the pixelated image with a constant radius surrounding the inclusion;
calculating a derived clarity grade for the gem as a function of the relief parameter for each inclusion, and the parameterized locations of the mapped inclusions.
