Abstract:

This research was aimed at determining the most suitable image detection operator to be used on a fiber optic connector endface profile from a fiberscope. The contemporary edge detection techniques analyzed are the Canny, Sobel, Prewitt, Laplacian of the Gaussian (LoG), Roberts and Frei-Chen operators using the Matlab® 2013 script. Histogram equalization was implemented on the connector profiles at the onset to improve the performances of the operators. By using the “task-based” empirical evaluation whose figure of merit is the sum total of edges detected, the Canny operator emerged the best candidate technique after yielding the maximum value of 139.1 average detections per section (adps) closely followed by the Laplacian of the Gaussian (LoG) with 103.2 average detections per section. The Sobel, Prewitt, Roberts and Frei-chen operators yielded 49.3, 49.57, 45.19 and 50.98 average detections per profile section respectively
