Quality factors of tobacco leaves were extracted and quantized using computer image processing and near infrared analysis. The efficiency of quality factors in tobacco leaf grading was analyzed statistically and major quality factors were determined under computer image processing and NIR spectrum measurement. This research was done as a prerequisite process to develop the real time on-line automatic grading system of tobacco leaves. Spectrophotometer was used to analyze the color of the tobacco leaves in grading. Computer image processing was also done to measure external quality features of each grade of tobacco leaves such as color, size, and shape. The optical reflectance property of the internal chemical compound in the range of 800-1200nm was also measured using a spectrophotometer for the purpose of real time implementation. Tobacco leaves used for this research were classified using standard grade criteria.
