Projects:

  • DIVA: Deep Intermodal Video Analytics.
  • Develop algorithms for robust automatic activity detection in a multi-camera streaming video environment. Activities will be enriched by person and object detection. DIVA will address activity detection for both forensic applications and for real-time alerting. [setup script] [docker images]

  • MDP Labeler: An interactive multiple object tracking dataset annotation tool based on apprenticeship learning.
  • Developing an interactive multiple object tracking annotation and analysis tool, enables user to fast annotate and analyze object trajectories in unconstrained videos.[code]

  • People counting based on head detection combining Adaboost and CNN in crowded surveillance environment.
  • Developing a person counting system combined Adaboost algorithm with CNN framework. The false alarm rate is greatly reduced with the proposed method.

  • MyFlower: An automatic flower species recognition system.
  • We construct a two-stream contextualized Convolutional Neural Network (CNN) for flower recognition.[poster]
