I am a Ph.D. student at University of California, Riverside advised by Dr. Amit K. Roy Chowdhury and Dr. Konstantinos Karydis. My research revolves around how autonomous systems perceive this world and building pipelines that can enable them to understand scenes using minimal supervision just as humans do.

I received my Bachelor in Technology (BTech.) degree in Computer Science and Engineering from University of Calcutta, India. I am fortunate to be advised by some amazing researchers over the years. I interned at Siemens with the Future of Automation (FoA) division on designing sensor realistic LiDAR simulation systems. I am a recipient of the MITACS Globalink Fellowship and worked with Prof. Jiju Poovvancheri at GSC Lab, Saint Mary's University on skeleton extraction for motion capture. Earlier, I spent consecutive semester breaks at Indian Institute of Science working with Prof. Anirban Chakraborty at VCL Lab and Prof. Kunal Narayan Chaudhury at LISA Lab on person-reidentification and lipschitz regularization respectively. I have also worked extensively with Prof. Amlan Chakrabarti on action recognition from videos.

Research Interests

I am currently focused on enhancing the perception capabilities of robotic systems by developing robust and generalizable world representations, with a particular interest in leveraging foundation models for comprehensive scene understanding. I have also worked on pose estimation under occlusions. My previous work encompassed various sub-domains, including video understanding, person-reid and shape approximation methods with an emphasis on utilizing unlabeled data for real-world applications.


I am always open to new collaborations and research ideas. Feel free to reach out if you are interested in working together!

TSCLite: A powerful and lightweight Traffic Sign Classification model Implementation
Sarosij Bose*, Avirup Dey*

Won 1st position in AI Entrepre-Neural, 2021 by GES, IIT Kharagpur and Intel

This work focuses on two lightweight Traffic sign classification implementations which can predict Traffic signs from any real time video feed. Here, a model based on an slightly enhanced LeNet architecture has been used and trained on the German Traffic Sign Dataset (GTSD) which has over 70000 images of traffic signs and over 40 various classes. Our model achieves a validation accuracy of over 98% and a training accuracy of over 97%. This saved model is then optimized over the Intel OpenVINO Model Optimizer + Inference Engine and run directly for predicting Traffic signs live from any video source(we have used webcam for our run). We have also provided a non optimized solution for comparison purposes.

PyTorch implementation of this paper

This project is the unofficial implementation of the paper "Towards Frequency-Based Explanation for Robust CNN". It primarly deals with the extent to which image features are robust in the frequency domain. Here, the DCT Transform, the pre-trained ResNet 18 model and the RCT maps are generated from the adversarial as well as the normal images.
