  • DSCLRCN saliency detection paper released. See Publications.
  • Our new saliency model, namely, Deep Spatial Contextual Long-term Recurrent Convolutional Network (DSCLRCN), ranks top on the mit300 and SALICON benchmark datasets. The paper is coming soon!


I am a fifth year Ph.D. student of School of Automation, Northwestern Polytechnical University (NPU), majoring in Pattern Recognition & Intelligent Systems, supervised by Prof. Junwei Han. Before that, I worked as a master candidate from Sept. 2012 to Jul. 2014 under the supervision of Prof. Han in NPU. I received the B. Eng degree from Honors College at NPU in 2012.

From Dec. 2016 to Dec. 2017, I was a visiting Ph.D. student in Vision and Learning Lab, at Electrical Engineering and Computer Science, University of California at Merced, under the supervision of Prof. Ming-Hsuan Yang. What a precious experience to work with Ming-Hsuan!

Research Interests

My research interests include computer vision related topics and deep learning. Now I mainly focus on saliency detection.
