Welcome to my personal page

I am a third year Ph.D student at University of Surrey under the supervision of Prof. Tao Xiang and Prof. Yi-Zhe Song. I also work closely with Dr. Xiatian (Eddy) Zhu.

Prior to joining University of Surrey, I was an AI Researcher at WeBank under the lead of Dr. Lixin Fan and I was a lab member of CISIP in University of Malaya (UM) under Prof. Chan Chee Seng.

My Projects

Image Generation with Diffusion

  1. DreamCreature - Generate images of novel creatures by mixing parts with stable diffusion.

Deep Watermarking

  1. DeepIPR (NeurIPS 2019) - Watermarking our DNNs by embedding “passport” and “signature”.
  2. IPR-GAN (CVPR 2022) - Protecting our GANs by generating watermarked images.

Deep Hashing for Image Retrieval

  1. DPN (IJCAI 2020) - Bit-wise hinge loss with random orthogonal codebook.
  2. OrthoHash (NeurIPS 2021) - Cross entropy loss with random orthogonal codebook.
  3. FIRe - Open source Fast Image Retrieval framework.
  4. SDC (BMVC 2023 Oral) - Unsupervised hashing by maximizing the utilization of hash spaces through Wasserstein distance.
