Research Interest

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
