An electronic corn kernel size grading system was developed using machine vision. Measurements of kernellength, width, and projected area were obtained independent of kernel orientation. The performance of the size-gradingalgorithm was compared to the results of mechanical sieving using a precision round-hole seed sizer. Average accuracyfrom 73.8% to 90.3% was achieved on seed corn samples that were pre-sized using precision graders.
