Malaria remains one of the leading causes of death globally, necessitating continuous research into novel diagnostic and treatment methods. Despite available treatments, accurately assessing drug efficacy against malaria parasites remains challenging due to the need for precise parasite quantification in blood-smeared images, a task traditionally performed using time-consuming microscopy methods. In this study, we propose a Convolutional Neural Network (CNN)-based deep learning model to enhance malaria parasite detection from Giemsa-stained thin blood smears. The proposed model incorporates advanced preprocessing techniques, including normalization, standardization, and staining, as well as data augmentation methods (e.g., random cropping, flipping, and rotation) and hyperparameter optimization to significantly improve performance. The primary dataset from the National Institutes of Health (NIH), consisting of 27,558 parasitized and uninfected cell images, was used to train and evaluate the model. A custom CNN architecture was compared with pre-trained models like VGG-19, ResNet-50, and MobileNetV2 based on accuracy, precision, recall and AUC. The best-performing model achieved a training accuracy of 96.88%, validation accuracy of 95.55%, and test accuracy of 95.67% after 50 epochs. Performance metrics such as precision (97.37%), recall (97.75%), and AUC (99.19%) demonstrated high sensitivity and specificity, confirming the model’s robustness. A secondary dataset from the IEEE repository, containing 43,434 images, was used to validate the model, yielding near-identical performance and further confirming its generalizability across diverse datasets. These findings underscore the proposed model’s ability to accurately detect malaria parasites, offering a faster and more reliable alternative to traditional microscopy. Future work will explore integrating mobile-based imaging systems with cloud and edge-based inference for deployment in low-resource settings, aiming to enhance malaria treatment outcomes in underserved regions.
