Pre-processing methods in chest X-ray image classification Pre-processing methods in chest X-ray image classification

Abstract

The above-mentioned experiments provided some promising results. We used 4 parameters for the evaluation methods-accuracy, precision, recall, and F1-score. The parameters were calculated using a confusion matrix (presented in [pone.0265949.g003]) reporting the number of true positives (TP), true negatives (TN), false positives (FP), and false negatives (FN). The evaluation parameters were calculated using Eqs (8-1)$2$-(8-2)$5$.
