  • Abstract:
  • Automated blood cells detection helps with the consistent analysis of blood smear images. Manual examination is quite time-consuming. In this project, we propose a deep learning ensemble framework that combines three object detection models for detecting mainly three cells – White Blood Cells (WBC), Red Blood Cells (RBC), and Platelets. The images used here are from the TXL-PBC dataset of 1260 images that are already annotated. The models in the ensemble are YOLOv8n, YOLOv11n, and Faster R-CNN. The predictions of these models were combined using Weighted Boxes Fusion (WBF) as a baseline and a Class Rarity Adaptive Weighted Boxes Fusion (CRA-WBF). The CRA-WBFcomputes fusion weights per model and per class. The models have achieved validation mAP50 of 98.85%, 98.51%, and 96.34%. On the test set, WBF achieved an overall mAP50 of 97.409% and CRA-WBF 97.411%.
