Designing lensless imaging systems to maximize information capture
Leyla A. Kabuli, Henry Pinkard, Eric Markley +2
Mask-based lensless imaging uses an optical encoder (e.g. a phase or amplitude mask) to capture measurements, then a computational decoding algorithm to reconstruct images. In this…
ConvRML: High-Quality Lensless Imaging with Random Multi-Focal Lenslets
Leyla A. Kabuli, Clara S. Hung, Vasilisa Ponomarenko +2
Mask-based lensless imagers use simple optics and computational reconstruction to design compact form factor cameras with compressive imaging ability. However, these imagers genera…
Scalable dataset acquisition for data-driven lensless imaging
Clara S. Hung, Leyla A. Kabuli, Vasilisa Ponomarenko +1
Data-driven developments in lensless imaging, such as machine learning-based reconstruction algorithms, require large datasets. In this work, we introduce a data acquisition pipeli…
Estimation-theoretic analysis of lensless imaging
Leyla A. Kabuli, Nalini M. Singh, Laura Waller
We analyze lensless imaging systems with estimation-theoretic techniques based on Fisher information. Our analysis evaluates multiple optical encoder designs on objects with varyin…
