In this paper few edge detection techniques viz. Optimal & Template Based are compared to inspect the over and under fill liquid level of bottle in machine vision system. The text represents the steps and approaches for the inspection of over and under filled level in the bottle which would not only be helpful for quality inspection but in pr?cised time too using different edge detection techniques. The results of Shen-Castan's ISEF optimal edge detection algorithm were found to be much better than the traditional edge detection methods like Roberts, Prewitt, Sobel, Marr-Hilderth LoG algorithm and Canny algorithm.
