Analysis of self-correcting active pixel sensors

Khaled Salama, Ahmad Al-Yamani, Rene Rasmussen, Yoichi Miyake
2005 Image Quality and System Performance II  
We show that in the absence of stuck faults (i.e., no errors) the performance of the system suffers from considerable degradation especially at low illumination (i.e., typical indoor scenes).  ...  We use the same model to quantify the number of defective pixels under which self correction is beneficial.  ...  Acknowledgements I would like to thank Professor Edward J. McCluskey, for his helpful discussions and providing feedback.  ...
