This year, I am a postdoc researcher at ANIMA team (please visit my new page here)
I finished my PhD with Pervasive team, Oct 2016 – Jun 2020. Under the supervision of Prof. James Crowley and Remi Ronfard, I worked on the recognition of human manipulation actions.
This thesis addresses the problem of recognition, modelling and description of human activities. We describe results on three problems: (1) the use of transfer learning for simultaneous visual recognition of objects and object states, (2) the recognition of manipulation actions from state transitions, and (3) the interpretation of a series of actions and states as events in a predefined story to construct a narrative description.
- Video narration:
Key-frame proposals for video understanding:
This project is a continuation of last year’s work funded by NeoVision on key-frame selection for action recognition.
- – Action recognition using state-transformations:
In this project, we are interested in modeling actions to be the cause of object-state transformations. Object states can be more apparent from still images that some actions.
Most techniques models actions directly from images, we propose to use one of these SOA techniques and adapt them to model actions as state transformation.
This project aims to participate in the EPIC-Kitchens action recognition challenge. It requires skills in deep learning and in particular Pytorch.
