Jie's Exploration Fairyland

Give the machine a sensible Eye

I am a second-year CS master student at the University of Rochester, working with Prof. Chenliang Xu and Prof. Jiebo Luo. Prior to that, I received my B.S. degree in Electronic Information and master in Communication and Information System from Beijing Normal University.
My general research interest lies in computer vision, especially in video analysis, action recognition. [CV]

Projects

Weakly-supervised video actor-action segmentation

Project leader @University of Rochester, Oct. 2017 ~ Now
  • video-level weakly-supervised actor-action segmentation -- involve the tasks of video object segmentation and action recognition -- on A2D (unconstrained in-the-wild YouTube videos)
  • in the complete absence of pixel-wise annotation, achieve 72% mIoU of the best fully-supervised model on A2D
  • also achieve state-of-the-art performance on weakly-supervised video object segmentation on the YouTube-Object dataset
  • robust to real-world adverse conditions: background clutter, motion blur, low illumination, occlusion, out of view, and small scale, etc. [Demo]

Spatial-temporal action localization in AVA dataset

Full-time Research Intern (Mentor: Lijuan Wang) @Microsoft Research, Seattle, May. 2018 ~ Aug. 2018
  • Transfer the long-term modeling in successful speech recognition architectures to long duration action sequence prediction on AVA dataset.
  • Model multi-person contextual dependency by means of spatial action heatmap.
  • Replicate the faster-rcnn+I3D based model that wins the AVA Challenge 2018 at the CVPR workshop.
