This study presents the development of a neural network-based classifier for the diagnosis of childhood pneumonia using chest X-ray images. The database used contains anteroposterior radiographs from retrospective cohorts of pediatric patients aged one to five years from the Guangzhou Women and Children’s Medical Center. Using a routine developed in MATLAB, seven texture features were extracted from each image: mean, standard deviation, entropy, contrast, correlation, energy, and homogeneity. These features were used as inputs for a feed-forward artificial neural network designed to classify the images as normal or associated with bacterial pneumonia. The database consisted of 49 normal images and 48 images with bacterial pneumonia. The best-performing neural network achieved an overall accuracy of 96.9%, suggesting that the proposed approach may constitute an efficient and interpretable tool to support computer-aided diagnosis. However, the reduced size of the dataset and the lack of external validation limit the clinical generalizability of the model, an aspect that should be addressed in future research.
