Research Interest
My primary focus is on Generative Models, Diffusion Models, Video Editing, Image Editing. My recent works include:
•
• Enhanced video editing by developing a ‘motion word’ approach, enabling subject replacement across diverse body structures and increasing text alignment up to 7.66%.
• Identified and resolved a conflict among embeddings in zero-shot text-to-image (T2I) customization using orthogonal embedding, improving text alignment by 3.82-5.26% and image alignment by 2.11-12.2%.
