Researchers have developed QuantaFlow, a novel method for calculating dense optical flow directly from single-photon avalanche diode (SPAD) camera streams. This technique addresses the challenges of motion blur and underexposure in high-speed, low-light conditions by embedding the construction of SPAD representations into an iterative flow refinement process. QuantaFlow dynamically aligns camera slices and constructs multi-scale representations that balance photon noise with residual motion blur, enabling more accurate flow estimation. The method has been validated on both synthetic and real-world SPAD data, demonstrating its effectiveness and generalization capabilities. AI
