The purpose of this study is to detect jamming in sealing aluminum vacuum metallized film packaging for food material. Two types of package are examined; one is unpigmented silver packaging and the other is red colored. The detection algorithm developed in this study consists of the following methods: capturing 24 bit image data of the package's seal area; decomposition of the RGB components (8 bits each); determination of the seal area, gray scale transformation, FFT, image denoising by a mask operation, IFFT, edge treatment and binary conversion by applying a brightness threshold. The optimum brightness threshold is calculated by discriminant analysis. The combined optimum brightness thresholds for the detection of jamming in unpigmented silver packaging are a brightness threshold of 55 and a threshold of 35 using the B-component of the image data. The discrimination ratio of the jamming package is 99.6% under the above conditions. For red colored packages, the optimum brightness thresholds for detecting jamming are a brightness threshold of 60 and a brightness threshold of 43 using the B-component of the image data, giving a discrimination ratio of 94.3%. It was showed that the detection of jamming in sealing food packages is possible by the detection systems developed in this study.<br>
