Estimation of visual quality of injection-molded polymer panels
Abstract
A new machine vision approach for estimating manufactured product appearance is illustrated. This new approach consists of: (1) extraction of textural information from product images, (2) estimation of measures of the visual quality of the product from the textural information extracted. This method is specifically aimed at treating the stochastic nature in the visual appearance of many manufactured products. This non-deterministic nature of product appearance has been a main obstacle for the success of machine vision in the process industries. This approach is successfully applied to an industrial process for estimation of the visual appearance of injection-molded plastic panels.
