| Proposed segmentation | 0. 9526 | 0.157 | Stronger | Less | Complex |
| Robert | 0.8299 | 0.75 | Weak | Much | Low noise |
| Sobel | 0.8712 | 13.969 | Weak | More | Low noise and gray changes gradually |
| Prewitt | 0.7118 | 13. 897 | Weak | Much | Low noise and gray changes gradually |
| Laplace | 0.7711 | 21.61 | Weak | Much | Low noise |
| Canny | 0.9125 | 21.932 | Little strong | Much | Little complex |
