Mikihiro Ikura (Ph.D.) is a project researcher in Department of Human and Engineered Environmental Studies, Graduate School of Frontier Sciences, The University of Tokyo, and a Computer Vision engineer at a Japanese startup company called Softroid inc. My major is high speed image processing, 3D sensing, and Robotics at Real World Robot Informatics Laboratory. In particular, my research focused on an adaptive 3D sensing system with adjustable spatio-temporal resolution and measurement in real time, a real-time video superimposition with cooperative teleoperated robots, and robust and efficient vehicle detection in Intelligent Transportation Systems. During my Ph.D course, I stayed at Technical University of Munich and German Aerospace Center for 1.5 years to engage in the research related to event-based cameras and spiking neural networks.
