In this paper, digital image analysis is applied for
non-destructive classification of rice and sticky rice seeds that are
mixed together. It is a difficult task because of the similar surface
color of the seeds. This paper presents an automatic classification
method based on RGB color features. Hardware of image
capturing is designed using back light source in order to
maximize the contrast between the rice seeds and their
background. RGB histogram is then calculated. The rule of
classification between rice seed and sticky rice seed are created.
Almost 97% of rice seeds are identified correctly. The correct
classification rates for two rice varieties are: rice seeds ‘Jasmine’
96.34% and sticky rice seeds 100%.
