Outstanding Performance Award for Bachelor Theses [Mar. 2019]
My bachelor thesis topic is “Task-oriented Function Detection Based on Operational Tasks”. I proposed an alternative representation to Affordance, “Task-oriented Function”, in the paper. This representation makes it possible to desribe a variety of ways to use an object, though only one usage can be described in Affordance Detection in the field of Computer Vision.

3rd place award in MIRU 2018 Young Researchers Program [Aug. 2018]
As a young researcher program in MIRU 2018, participants were divided into several groups and each group read papers in the field outside Computer Vision. Then, each group summarized the history, the trend and the conection with Computer Vision. It helped us not only understand different fields, but also consider how we can make use of knowledge about them for Computer Vision.
Our group, C, read papers in the field of Robotics, focusing on “Transferring Knowledge from Simulation to Real”. You can see our poster and presentation material from this link.
