Researchers have developed a new framework for modeling and calibrating noise in single-photon avalanche diode (SPAD) cameras, which are promising for low-light imaging. The proposed model addresses challenges unique to SPADs in intensity imaging mode, where explicit noise decomposition is difficult due to the absence of photon timestamps. The framework includes a Binomial observation process for binary-frame accumulation, models signal-independent dark noise, and accounts for pixel-wise response non-uniformity. A dedicated calibration procedure and a SPAD-specific dark-shading correction method are also introduced to improve denoising performance. AI
