Jingyun Liang

I am currently a PhD Student at Computer Vision Lab, ETH Z├╝rich, Switzerland. I am co-supervised by Prof. Luc Van Gool and Prof. Radu Timofte. I also work closely with Dr. Kai Zhang. I mainly focus on low-level vision research, especially on image and video restoration, such as super-resolution, deblurring and denoising.
