Development and implementation of a digital scoring model for evaluation of shine in automatic dishwashing

Room: 405
Abstract: Dow Home and Personal Care has developed a protocol using a digital imaging station and statistical model to assist in standardizing data collection and analysis in automatic dishwashing (ADW). Currently, human panel observations based on ASTM D3556-14 are used to provide numerical ratings for filming and spotting on glassware. This approach can give results with significant variability between raters and sites. This talk will present progress towards a standardized and semi-automated methodology for shine evaluation. The proposed technique is based on a combination of a custom imaging station built in house, standard image analysis techniques and a statistical model. The model was built by correlating objective values derived from the collected images to a series of panel ratings from an array of glasses, giving computed ratings which agree closely with experimental scores assigned by experienced human raters.
