I am a first-year PhD student at the University of Bristol working with Prof. Dima Damen. My research interest is Computer Vision, Pattern Recognition, and Machine Learning. Currently, I am working on devising learning-based methods for understanding and exploring various aspects of first-person (egocentric) vision. Previously, at CVIT, IIIT Hyderabad, I worked with Prof. C.V. Jawahar and Prof. Chetan Arora on unsupervised procedure learning from egocentric videos. Earlier, I worked on improving word recognition and retrieval in large document collection with Prof. C.V. Jawahar and on 3D Computer Vision with Prof. Shanmuganathan Raman.
My ultimate goal is to contribute to the development of systems capable of understanding the world as we do. I’m an inquisitive person, and I’m always willing to learn about fields including, but not limited to, science, technology, astrophysics, and physics.

We propose the EgoProceL dataset consisting of 62 hours of videos captured by 130 subjects performing 16 tasks and a self-supervised Correspond and Cut (CnC) framework for procedure learning. CnC utilizes the temporal correspondences between the key-steps across multiple videos to learn the procedure.

We offer 3,670 hours of daily-life activity video spanning hundreds of scenarios captured by 931 unique camera wearers from 74 worldwide locations and 9 different countries.
We present a host of new benchmark challenges centered around understanding the first-person visual experience in the past (querying an episodic memory), present (analyzing hand-object manipulation, audio-visual conversation, and social interactions), and future (forecasting activities).
