Then, dermoscopic images are acquired<br \/>\nfor lesions identified as suspicious during the initial clinical assessment, allowing a more detailed examination.<\/p>\n<p>The presented research contributes to the workflow and advances the field through four key contributions. First, we review clinical image-based diagnosis, identifying successful methods and unresolved challenges, then deploy a pre-trained model for clinical image classification. Second, we design compact deep learning models for real-time dermoscopic melanoma detection by integrating attention mechanisms to improve accuracy while reducing computational costs. Third, we expand the dermoscopic diagnosis to include other types of skin cancer and enhance performance through clinically structured labeling. The resulting ensemble model outperforms existing approaches while balancing sensitivity and specificity for realworld use. Finally, we integrate vision-language models to provide dermoscopiclevel explainability, ensuring transparent and interpretable diagnoses.<\/p>\n<p>Together, these contributions enable accurate, scalable, and clinically viable skin cancer detection systems across two imaging modalities with the final objective of improving patient outcomes and reducing mortality rate.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By: Sana Nazari Supervised by:\u00a0 Dr. Rafael Garcia &nbsp; Abstract: Skin cancer remains one of the most prevalent and deadly forms of cancer worldwide, with melanoma alone accounting for over 330,000 new cases and nearly 60,000 deaths in 2022.
