Anil Kumar Vadathya

I am a Research Engineer at the Department of ECE, Rice University. I work with Prof. Ashok Veeraraghavan computational imaging group in the intersection of computer vision, machine learning and imaging. I am also a visiting researcher with Dr. Teresia O'Connor group at Baylor College of Medicine where I led significant machine learning and data collection efforts for multiple NIH grants to develop and deploy state-of-the-art computer vision algorithms to objectively measure children's TV and mobile use behaviors.

Before joining Rice, I finished my masters in Electrical engineering with Dr. Kaushik Mitra at IIT Madras, where I worked on generative models for image restoration in computational imaging frameworks. My master's thesis work won Qualcomm Innovation Fellowship for the year 2016-2017. I got my B. Tech in Electronics and Communications from RGUKT, Basar, India in 2015.

Research

Broadly I'm interested in the computer vision, machine learning, and generative models and their applications. I love building state-of-the-art AI products for challenging problems.

	FLASH-TV a machine learning pipeline to passively measure children's TV viewing: validation studies of the system Anil Kumar Vadathya, Tom Baranowski, Teresia M O'Connor, Alicia Beltran, Salma M Musaad, Uzair Alam, Alex Ho, Jason A Mendoza, Sheryl O Hughes, Ashok Veeraraghavan In print at Nature Scientific reports, 2024 code / project We validated a camera based privacy-preserving tech to track TV viewing in real-time in the participant's home. This technology is now being deployed in a 5-year NIH study with 200 children to measure impact of screentime on their health.
	Development of family level assessment of screen use in the home for TV (FLASH-TV) Anil Kumar Vadathya, Tom Baranowski, Teresia M O'Connor, Alicia Beltran, Salma M Musaad, Oriana Perez, Jason A Mendoza, Sheryl O Hughes, Ashok Veeraraghavan Multimedia Tools and Applications, 2023 code / paper Technical report on FLASH-TV, an objective tool to measure TV time.
	The Family Level Assessment of Screen Use-Mobile Approach: Development of an Approach to Measure Children's Mobile Device Use Oriana Perez, Anil Kumar Vadathya, Salma Musaad, Alicia Beltran, R Matthew Barnett, Tom Baranowski, Sheryl O Hughes, Jason A Mendoza, Ashutosh Sabharwal, Ashok Veeraraghavan, Teresia O'Connor JMIR Formative Research, 2022 code / paper
	An Objective System for Quantitative Assessment of Television Viewing Among Children (Family Level Assessment of Screen Use in the Home-Television): System Development Study Anil Kumar Vadathya, Salma Musaad, Alicia Beltran, Oriana Perez, Leo Meister, Tom Baranowski, Sheryl O Hughes, Jason A Mendoza, Ashutosh Sabharwal, Ashok Veeraraghavan, Teresia O'Connor JMIR Pediatric and Parenting, 2022 code / paper / project Technical report on FLASH-TV alpha and beta tests.
	A unified learning-based framework for light field reconstruction from coded projections Anil Kumar Vadathya, Sharath Girish, Kaushik Mitra IEEE Trans. on Computational Imaging, 2018 poster / code / arxiv We provide a learning algorithm for light field reconstruction from a conventional camera.
	Solving Inverse Computational Imaging Problems using Deep Pixel-level Prior Akshat Dave, Anil Kumar V., Ramana Subramanyam, Rahul Baburajan, Kaushik Mitra IEEE Trans. on Computational Imaging Accepted at Deep Generative Models applications (TADGM) workshop at ICML, 2018! arxiv / code We use a deep autoregressive image prior PixelCNN++ for solving inverse imaging problems. Since autoregressive nature explicitly models pixel level dependencies it reconstruct pixel level details much better than existing state of the art methods.
	Learning Light Field Reconstruction from a Single Coded Image Anil Kumar V., Saikiran C., Gautham R., Vijayalakshmi Kanchana, Kaushik Mitra Asian Conference on Pattern Recognition, 2017 project page / poster Using deep neural networks we reconstruct full sensor resolution light field from a single coded image. Our approach involves depth based rendering where depth is learnt in an unsupervised manner.
	Compressive Image Recovery Using Recurrent Generative Model Akshat Dave, Anil Kumar Vadathya, Kaushik Mitra International Conference on Image Processsing (ICIP), 2017 project page / github / poster We use a deep recurrent image prior, RIDE, which can model long range dependencies in images very well. Using this for compressive image recovery we show much better reconstructions especially at lower measurement rates.
	Denoising High Density Gene Expression in Whole Mouse Brain Images Mayug Maniparambil, Anil Kumar V., Kannan U. V., Kaushik Mitra, Pavel Osten Society for Neuroscience (SfN), 2017 poster We use a deep autoencoder with adversarial loss for denoising the gene expression to improve the registration accuracy.
	Butterfly Communication Strategies: A prospect for soft-computing techniques Sowmya Charugundla, Anjumara Shaik, Chakravarthi Jada, Anil Kumar Vadathya International Joint Conference on Neural Networks (IJCNN), 2014 BMO code for three peaks function. We show mathematical models of communication mechanisms debloyed by butterflies. This work is extended to an optimization algorithm, Butterfly Mating Optimization (BMO), Jada et al. 2015. We applied it for image clustering application.
	ROBOG Autonomously Navigating Outdoor Robo-Guide Kranthi Kumar R., Irfan Feroz G. M., Chakravarthi Jada, Harish Y., Anil Kumar V. International Conference on Swarm, Evolutionary, and Memetic Computing, 2014 Neural networks are used to learn the navigation information. For outdoor navigation, we propose an image processing pipeline for road detection.
