Diffusion models applied to skin and oral cancer classification
It addresses medical image classification for skin and oral cancer diagnosis, but is incremental as it applies an existing method to new data with competitive results.
This study applied diffusion models to classify skin and oral cancer images, achieving balanced accuracies of 0.8357 for binary skin cancer classification and 0.9050 for oral cancer classification, showing competitive performance against state-of-the-art models.
This study investigates the application of diffusion models in medical image classification (DiffMIC), focusing on skin and oral lesions. Utilizing the datasets PAD-UFES-20 for skin cancer and P-NDB-UFES for oral cancer, the diffusion model demonstrated competitive performance compared to state-of-the-art deep learning models like Convolutional Neural Networks (CNNs) and Transformers. Specifically, for the PAD-UFES-20 dataset, the model achieved a balanced accuracy of 0.6457 for six-class classification and 0.8357 for binary classification (cancer vs. non-cancer). For the P-NDB-UFES dataset, it attained a balanced accuracy of 0.9050. These results suggest that diffusion models are viable models for classifying medical images of skin and oral lesions. In addition, we investigate the robustness of the model trained on PAD-UFES-20 for skin cancer but tested on the clinical images of the HIBA dataset.
