Digital Image Processing Applied to Seed Purity Test

Abstract: In this paper we used digital image processing techniques for purity test of various seeds. Physical purity analysis tells us the proportion of pure seed component in the seed lot. The computer software which can predict seed image for seed lot by using digital image processing techniques is developed. Due to the advance of camera technology, people can take digital pictures easily in any places and any time by a camera or by a mobile phone device. Moreover, it is easy to transform and process by using a computer system. Thus, this project employs a digital camera to capture the image. This paper studies various digital image processing techniques which reduces the labor input required to evaluate seedling growth rate and increases the accuracy of these measurements.
