I am a thrid-year CS PhD student @ CS Department of University of Maryland, College Park, advised by Professor Christopher Metzler.
Previously, I had a wonderful journey (2020-2022) in X-Pixel with my supervisor Prof. Dong Chao (Shanghai AI Lab) and mentor Dr. Gu Jinjin (Univeristy of Sydney).
Research Interest - Computational Photography, Gen AI and Low-level Vision.
This paper presents a new deep learning framework for removing snow from videos, featuring a high-quality dataset and innovative modules for effective snow removal, outperforming existing methods.

This paper highlights the challenge IQA faces with emerging GAN-based image restoration methods, noting a growing disparity between quantitative metrics and perceptual quality. To address this, the authors introduce a large-scale IQA dataset and benchmarks to enhance IQA methods’ effectiveness.
SRPO is a real-time super-resolution method for computer graphics, achieving superior visual effects with minimal computational cost by leveraging rasterized image features and offset prediction.
Efficient image super-resolution using vast-receptive-field attention
This study improves super-resolution networks by refining the attention mechanism, leading to VapSR, which outperforms lightweight networks with fewer parameters, achieving similar results as IMDB and RFDN networks with significantly fewer parameters.
Blueprint separable residual network for efficient image super-resolution
This paper presents CUGAN, a Controllable Unet GAN, for modulating image restoration tasks with fine texture details. Through dynamic level adjustments and condition networks, CUGAN outperforms previous methods, offering smooth user control over output effects.
