Dhawal Sirikonda

I'm a PhD candidate at Dartmouth working with Prof. Adithya Pediredla in the Rendering and Imaging Science Lab (RISc). My research focuses on building novel imaging systems by leveraging various sensor modalities (namely event cameras, RGBD sensors, etc.). My current research focuses on novel acousto-optic imaging systems for fast scanning and communication applications. I am particularly interested in exploring ways to harness ML and non-ML methods for various real-world applications. Prior to my PhD, I completed my Master’s working with Prof. PJ Narayanan at the intersection of 3D Vision and Real-Time Graphics.

Research Interests

Some things I'm interested in:

• Sensors (ToF, motion contrast, etc.)
• ML for imaging
• Processing sensor data
• HPC and automation for real-world applications

Personal

Some personal facts:

• I like capturing low-light images.
• Listening to music (less lyrical).
• Driving (I enjoy driving long distances).
• I collect a lot of superhero merchandise and am fond of bubble tea.
• I am borderline dyslexic (or maybe mildly dysgraphic, as ChatGPT suggests), so I occasionally (debatable 😬) invent new spellings for words like friend → freind or field → feild. And yes, this page has been corrected by ChatGPT.

Projects

• Using AO to Sculpt and Steer Light Planes at High Speeds for Scanning Applications

  Research Project

  This project focuses on leveraging Acousto-Optic (AO) techniques to dynamically sculpt and steer light planes at high speeds, enabling efficient and precise scanning applications.

• Underwater Communication

  Research Project

  This project explores the use of Acousto-Optic (AO) sculpting techniques to enhance underwater communication systems.

• Object Retrieval from Radiance Fields

  Research Project (with Dr. Rajvi Shah)

  Interactive object and sub-scene retrieval from scenes represented as Radiance Fields. The work involves growing high-confidence object content to encompass intricate details, aiming for accurate retrieval.

• Real-time Rendering of Implicit Surfaces using Precomputed Radiance Transfer

  Thesis · CVIT, IIIT-H, 2022

  A simple yet fast approach to address the lack of storage schema in the functional representation of surfaces for the incorporation of Precomputed Radiance Transfer (Spherical Harmonics) for both glossy and diffuse materials.

• Exploring Storage Schemas for Transfer Vector Storage

  Research Project · IIIT-H, 2022

  Exploration of storage schemas (UV and vertex attributes) to find optimal sampling and interpolation strategies for artifact-free renders.

• Appearance Editing and Novel View Synthesis of Captured Data

  Research Project · CVIT, IIIT-H, 2021

  Extends Novel View synthesis pipelines to accommodate appearance edits. Uses differentiable rendering to separate appearance, followed by a disentangled rendering framework.
