imgaug gmenters.pillike¶. Augmenters that have identical outputs to well-known PIL functions. The like in pillike indicates that the augmenters in this module have identical outputs and mostly identical inputs to corresponding PIL functions but do not have to wrap these functions internally. They may use internally different (e.g. faster) techniques to produce these outputs.

This study examined the physics of loose abrasive microgrinding (grinding with micron and submicron sized abrasives). More specifically it focused on the transition from brittle to ductile mode grinding which occurs in this region of abrasive sizes. Process dependency on slurry chemistry was the primary area of emphasis and was studied for diamond abrasives varying in size from 3.0 to 0.75
