The quality control process of the seal seams at Tetra Brik Aseptic carton package is traditionally performed by specialized workers in liquid food manufacturing businesses. Because it is based on the people, this control process has many drawbacks. In this study, it is aimed to perform the quality control of seal seams at carton package by a computer-aided system. Pixel-based image segmentation and Multi Layer Neural Network methods were used together, and it is tested on the images of carton packages provided by DIMES company. The results of the presented system were found to be satisfactory, and the recommendations are provided for the future studies.
