Edge detection becomes vital in recognizing the object of an image because the edge of the object in the image contains critical information, the information obtained can be either the size or shape of the object in the image. This study uses the Roberts operator, the Sobel operator, the Prewitt operator, and the Canny operator and make quality comparisons and analyze the four methods. The analysis shows that the calculation of PSNR on the Robetrs method has the highest value with an average of 44.19 dB, Sobel, Prewitt and Canny operators have PSNR values above 30 dB so that it is classified as a good image. Other quality comparisons use the histogram value and the contrass value with the highest value on the Sobel operators with an average histogram value of 22.06. Based on testing, it can be concluded that the Roberts operators have the best image quality.}, issn = {2338-0403}, doi = {10.14710/jtsiskom.2021.14209}, url = {https://jtsiskom.undip.ac.id/article/view/14209} }
