AJ Piergiovanni

I am a PhD student in Computer Science at Indiana University advised by Dr. Michael Ryoo. I work on computer vision, machine learning and robotics. I'm interested in the activity detection tasks, and especially enjoy applications to sports videos.

In 2015, I recieved a BS in Computer Science and Mathematics from Rose-Hulman Institute of Technology. In my free time, I climb mountains.

Datasets

MLB-YouTube: A dataset for activity recogntion in continuous and segmented baseball videos. Also included is dense text annotations from the commentators to allow for video captions and learning video and language relationships.
