| Título do trabalho | Synthetic Data Augmentation for Plasmocyte Detection in Bone Marrow Images |
| Resumo do trabalho | Accurate detection of plasmocytes in bone marrow microscopy images is a key step in the diagnosis of multiple myeloma, which relies on the plasmocyte-to-non-plasmocyte cell ratio. However, the limited availability of annotated medical data poses a challenge for training robust object detection models. In this work, we investigate the use of synthetic data augmentation to improve plasmocyte detection performance. We generate images of individual plasmocytes using multiple generative models, including diffusion models (U-Net-based), WGAN-GP, and Diffusion Transformers (DiT). These synthetic cells are then composited into real bone marrow microscopy images, with automatic generation of corresponding annotations. The resulting dataset is used to train a YOLO-based object detector, which is evaluated for plasmocyte detection. The research proposal focuses on designing a framework capable of creating synthetic cells to achieve two main purposes: augmenting data to improve performance in a clinically relevant diagnostic scenario, and supporting the training of specialists to identify plasma cells and reduce diagnostic errors. |
