SUN Hui, SUN Kai, HOU Qing-yu. Blind-pixel Detection Based on the Abnormality of Statistic Characteristic of Fixed Pattern Noise[J]. 2011, 16(2): 16-19.DOI:
The fixed pattern noise component of 3D noise model is used to detect blind-pixel of IRFPA as data source.It can be classified to dead pixel and over hot pixel by representable form of blind-pixel.As for dead pixel
the paper uses double-end dividing threshold value to detect dead pixel
which is determined by prior knowledge using quantity limited and low probability density characteristic of its hitstogram.But as for over hot pixel
it is regarded as abnormal pixel of Gaussian distribution noise
