Jeremy Klotz

I'm a Ph.D. student at Columbia University. I am advised by Shree Nayar, and my work is generously funded by the NDSEG fellowship. Before my Ph.D., I worked with Aswin Sankaranarayanan at CMU.

My research is in computational imaging. Specifically, I work on visual sensing methods that capture the least information necessary to solve a task. My work demonstrates that a minimalist approach to visual sensing brings a variety of benefits over conventional cameras, such as preserving privacy and enabling self-powered cameras. Recently, my research has taken a foray into imaging and vision for solar energy. Before coming to Columbia, I worked on structured light systems for 3D scanning and predicting fruit freshness.

An Eternal Irradiance Camera

An Eternal Irradiance Camera

Jeremy Klotz and Shree K. Nayar

SIGGRAPH Asia, 2026

We introduce FluxCam, a self-powered and untethered irradiance camera, and we demonstrate a few of its applications.
Minimalist Visual Inertial Odometry

Minimalist Visual Inertial Odometry

Francesco Pasti, Jeremy Klotz, Nicola Bellotto, and Shree K. Nayar

IEEE Robotics and Automation Letters (RA-L), 2026

We propose a minimalist sensing approach for robot odometry using 4 pixels and an IMU.
Forecasting Solar Energy Using a Single Image

Forecasting Solar Energy Using a Single Image

Jeremy Klotz and Shree K. Nayar

Solar Energy, 2026

We introduce a method to forecast a solar panel's irradiance (and hence its harvested energy) at any time in the future using a single image taken at the panel's location.

Minimal Sensing for Orienting a Solar Panel

Jeremy Klotz and Shree K. Nayar

Solar Energy, 2025

We introduce a minimal sensing method to iteratively orient a solar panel toward the optimal orientation in any lighting environment, regardless of the complexity of the illumination.

UrbanSky: A Dataset of Outdoor HDR Lighting Environments

Jeremy Klotz and Shree K. Nayar

UrbanSky consists of 1,067 outdoor HDR lighting environments (spherical images) in New York City.
Minimalist Vision with Freeform Pixels

Minimalist Vision with Freeform Pixels

Jeremy Klotz and Shree K. Nayar

ECCV, 2024 (Best Paper Award)

A minimalist camera captures the smallest number of measurements needed to solve a task. Rather than using square pixels, a minimalist camera uses freeform pixels whose shape are automatically learned for the task at-hand.

Cricket: A Self-Powered Chirping Pixel

Shree K. Nayar, Jeremy Klotz, Nikhil Nanda, and Mikhail Fridberg

Transactions on Graphics (SIGGRAPH), 2024

Cricket is a novel light sensor that can measure light without the use of a power supply or a battery.

Computational 3D Imaging with Position Sensors

Jeremy Klotz, Mohit Gupta, and Aswin C. Sankaranarayanan

ICCV, 2023 (Oral Presentation)

We introduce a low-bandwidth method for 3D scanning with position sensing diodes that is robust to global illumination.

Fine-Grain Prediction of Strawberry Freshness Using Subsurface Scattering

Jeremy Klotz, Vijay Rengarajan, and Aswin C. Sankaranarayanan

ICCV Workshop on Large-Scale Fine-Grained Food Analysis (LargeFineFoodAI), 2021

We show subsurface scattering measurements are useful for predicting fruit freshness.
