Abstract

Computer implemented methods to classify quench patterns of heat-treated uncoated or coated mineral glasses and predict the optical visibility thereof. The classification method takes as input a set of optical retardation image-maps of heat-treated coated mineral glasses, a set of optical visibility scores for quench patterns of said heat-treated uncoated or coated mineral glasses; a colour sensitivity factor of the heat-treated uncoated or coated mineral glasses, and provides as output a set of optimized values as parameters for components of an image processing pipeline to be applied to the optical retardation image-maps provided as input. The prediction method relies on an image processing pipeline set up with a set of optimized parameters which can be obtained with the classification. An outstanding benefit is to provide a qualitative and quantitative scoring method for the visibility of quench patterns of heat-treated uncoated or coated mineral glasses, which is based on measurable optical properties thereof.
