Comparison of the transfer learning-based pretrained DCNN models with works.
| Study | Method | Probability of classification (%) |
| (23) (Kaftandjian et al., [43]) | Region-based + reference + morphological geometrical fuzzy logic | 80% at 0% false alarms |
| (29) (Valavanis et al., [44]) | Graph-based (region growing + connectivity similarities) Geometrical, texture SVM, ANN, k-NN | 46%–85% |
| (28) (Zapata, vilar, Ruiz, [42]) | Region edge growing; geometrical + PCA multiple-layer ANN, adaptive network-based fuzzy inference system (ANFIS) | 79%–83% |
| (26) (Kumar, et al. [40]) | Edge, region growing, watershed texture, geometrical ANN | 87% |
| (19) (Lim, Ratnam [46]) | Thresholding, geometrical, multiple-layer ANN | 97% |
| (27) (Zahran et al., [41]) | Morphological + wavelet + region growing; Mel-frequency cepstral coefficients (MFCCs) and power density spectra ANN | 75% |
