Fundamental Recovery Bounds for SPAD Signals under Stationary Flux
Lior Dvir, Nadav Torem, Mohit Gupta +1
Single-photon avalanche diodes (SPADs) record light as a discrete stream of individual detections. The signal is stochastic. Its statistical structure depends on the sensor's opera…

NnD: Diffusion-based Generation of Physically-Nonnegative Objects
Nadav Torem, Tamar Sde-Chen, Yoav Y. Schechner
Most natural objects have inherent complexity and variability. While some simple objects can be modeled from first principles, many real-world phenomena, such as cloud formation, r…

Complex-valued Retrievals From Noisy Images Using Diffusion Models
Nadav Torem, Roi Ronen, Yoav Y. Schechner +1
In diverse microscopy modalities, sensors measure only real-valued intensities. Additionally, the sensor readouts are affected by Poissonian-distributed photon noise. Traditional r…
