Profile

I am a Postdoctoral Research Fellow at State Key Laboratory of Integrated Service Networks, Xidian University. Currently, I am focusing on research areas including video compression, video enhancement, and high dynamic range video generation.

Research and Publications

To date, I have authored over 10 scholarly articles and actively participate as a peer reviewer for top-tier journals and conferences such as T-CVST, T-NNLS, IJCV, AAAI, IJCAI, ACMMM, and so on. My work primarily explores the intersections of image processing and compression in digital media technologies.

Achievements

My research team, Kingslayer, secured third place in the Perceptual Metric Track at the 5th Workshop and Challenge on Learned Image Compression, Conference on Computer Vision and Pattern Recognition 2022.
