A novel method for blind element inspection of IRFPA based on traditional methods of blind pixels detection is proposed.This ameliorated algorithm uses the data extracted from homogeneous background for one time to calculate the noise signals,and then finds the threshold for blind pixels detection according to conception of OTSU and minimum interclass variance.Experimental results indicate that this new method is capable of real-time blind pixels inspection with high accuracy and low complexity in comparison with traditional algorithms.

Key words: IRFPA;OTSU;minimum interclass variance;blind pixels
