Apoorva Beedu
I am a PhD candidate at Georgia Institute of Technology advised by Dr. Irfan Essa and Dr. Justin Romberg.
My research interests are primarily focused on understanding actions and object's states in videos, and have previously worked on 6D object pose estimation and human activity recognition.
During the summer of 2021, I was an intern at Facebook Reality Labs, collaborating with Chengde Wan and Robert Wang.
In 2020, I undertook an internship at Microsoft Research with Dr. Amol Ambadekar.
In the summers of '18 and '17, I interned at a startup called NodeIn, working with Dr. Suresh Kannan.
Prior to joining Georgia Institute of Technology, I spent a year at Asteria Aerospace Limited as a software Engineer.

Video based Object 6D Pose Estimation using Transformers
Apoorva Beedu, Huda Alamri, Irfan Essa
NeurIPS 2022 workshop on Vision Transformers: Theory and Applications, 2022
arxiv
We introduce a Transformer based 6D Object Pose Estimation framework VideoPose, comprising an end-to-end attention based modelling architecture, that attends to previous frames in order to estimate accurate 6D Object Poses in videos.

Masked reconstruction based self-supervision for human activity recognition
Harish Haresamudram,Apoorva Beedu, Varun Agrawal, Patrick L Grady, Irfan Essa, Judy Hoffman, Thomas Plötz
Proceedings of the 2020 ACM International Symposium on Wearable Computers, 2020
arxiv
We introduce masked reconstruction as a viable self-supervised pre-training objective for human activity recognition and explore its effectiveness in comparison to state-of-the-art unsupervised learning techniques.
