METHOD FOR CONTROLLING THE APPEARANCE OF PRODUCTS AND PROCESS PERFORMANCE BY IMAGE ANALYSIS

摘要

A new application of machine vision for process industries is proposed. Theinvention consists of: (1) estimation of visual quality of products, (2)modeling causal relationship between estimated quality and process variables,and (3) optimization of visual quality using the causal model. This inventioncan handle the stochastic nature in visual appearance of products that processindustries provide, which has been a main obstacle for the success of machinevision in process industries. Also, it opens new tasks in machine vision suchas modeling and optimization of visual quality of products.
