Hi, I am Wenjun Ji. I am currently a junior at College of Software, Nankai University. I am working as a research intern at Media Computing Lab, Nankai University (2024.05 – Present), focusing on camouflaged object detection and AI security under the guidance of Prof. Deng-Ping Fan and Prof. Qing Guo. I am deeply grateful for their patient mentorship, which has guided me from a complete beginner to someone gradually growing in research
My research interests focus on camouflaged object detection and AI security. Recently, I am focusing on:
(1) improving the robustness of physical adversarial samples;
(2) adversarial attacks against camouflaged object detection.
My research aims to build intelligent systems that are both theoretically grounded and practically effective, with the ultimate goal of advancing AI safety and reliability in real-world deployments.
