Low Latency Gaze Tracking via Latent Optical Sensing
Yidan Zheng, Matheus Souza, Kaizhang Kang +3
We present a real-time gaze tracking system that directly acquires task-relevant latent features using a fully passive optical encoder. Instead of forming and processing full-resol…
Uncertainty Quantification in HSI Reconstruction using Physics-Aware Diffusion Priors and Optics-Encoded Measurements
Juan Romero, Qiang Fu, Matteo Ravasi +1
Hyperspectral image reconstruction from a compressed measurement is a highly ill-posed inverse problem. Current data-driven methods suffer from hallucination due to the lack of spe…
Limitations of Data-Driven Spectral Reconstruction -- An Optics-Aware Analysis
Qiang Fu, Matheus Souza, Eunsue Choi +3
Hyperspectral imaging empowers machine vision systems with the distinct capability of identifying materials through recording their spectral signatures. Recent efforts in data-driv…
Large-Area Fabrication-Aware Computational Diffractive Optics
Kaixuan Wei, Hector A. Jimenez-Romero, Hadi Amata +4
Differentiable optics, as an emerging paradigm that jointly optimizes optics and (optional) image processing algorithms, has made innovative optical designs possible across a broad…
Learned Off-aperture Encoding for Wide Field-of-view RGBD Imaging
Haoyu Wei, Xin Liu, Yuhui Liu +4
End-to-end (E2E) designed imaging systems integrate coded optical designs with decoding algorithms to enhance imaging fidelity for diverse visual tasks. However, existing E2E desig…
Latent Space Imaging
Matheus Souza, Yidan Zheng, Kaizhang Kang +3
Digital imaging systems have traditionally relied on brute-force measurement and processing of pixels arranged on regular grids. In contrast, the human visual system performs signi…
