Abstract

A product testing apparatus is described as having one or more imager configured to capture one or more images of a sample having a substrate coating applied to a substrate, a processor in communication with the imager, and a non-transitory processor readable medium, in communication with the processor. The non-transitory processor readable medium stores processor executable instructions that when executed cause the processor to receive the one or more images from the one or more imager. The processor then processes the one or more image by filtering lighting variations in the pixels of the one or more images to identify one or more objects of interest in the one or more images of the cured/uncured substrate coating. The processor quantifies one or more property of the one or more objects of interest. The processor executable instructions then cause the processor to generate one or more signal indicative of the quantification of the one or more objects of interest.
