My research lies at the intersection of visual perception, image processing, computer vision, and deep learning. I am particularly interested in developing advanced algorithms that bridge fundamental theory and real-world applications. Current research directions include:
✨Image resampling, including image super-resolution and image downsampling
✨Generative remote sensing image enhancement
✨HDR image production
✨Lightweight models for image enhancement
