Table 5 Confusion matrix to test the algorithm and watermarking scheme
From: A novel secured Euclidean space points algorithm for blind spatial image watermarking
Confusion matrix | Predicted NO: test bit, ‘binary 0’ | Predicted YES: test bit, ‘binary 1’ |
|---|---|---|
Actual NO: reference bit ‘binary 0’ | TN—true negative | FP—false positive |
Actual YES: reference bit ‘binary 1’ | FN—false negative | TP—true positive |
