An image is digitized and divided into small regions, called pixels. A gray level is given to each pixel based on the intensity of light received by the camera at the pixel location. Digitized images can be stored in the computer or on a tape or disk. Two terms commonly used are image processing and pattern recognition.
Image processing involves steps taken to enhance an image and extract pertinent information.
Pattern recognition involves procedures that allow the computer to identify and classify an object based on certain characteristics. For more information, please contact Dr. John. The wheat mill roller always has varying amount of garlic weed seed that has partially plugged the corrugations on the rollers. This noxious contaminant is very similar to the desirable wheat. The mixture of it and wheat will degrade the wheat quality.
