Manuai grading of cucumber is time consuming, tedious and costly. Therefore, machine grading system, incorporating computer vision, appears to be an attractive with a high potential for success. Its development involved the integration of a grading system with a vision system along with an IBM PC compatible, fluorescent lighting equipment, frame gabber, B/W CCD (charge coupled device) camera, VGA (video graphics array) monitor to grade stationary cucumber. Software, written in C, combined the functions of image capture, image processing, and control into one program. Image processing algorithms were developed to extract the geometric features of cucumber. Geometric features include length, area, perimeter, centroid, roundness and complex ratio. This grading system proved to be a reliable system for grading cucumber.
