Algorithms were developed to acquire and process color images of bulk grain samples of five grain types, namely barley, oats, rye, wheat, and durum wheat. The images were acquired using a video camera and were digitized using a frame grabber board. The images were stored on a personal computer from where they were accessed by an image processing program which extracted over 150 color and textural features. A neural-network-based classifier was developed to identify the unknown grain types. The color and textural features were presented to a back propagation neural network for training purposes. The trained network was then used to identify the unknown grain types. Results showed a classification accuracy of over 90% for all grain types.
