A REAL-TIME METHOD FOR SMALL TARGET DETECTION OF IR GUARD SYSTEM

A new method for small target detection of IR guard system was investi gated. According to the environmental characteristics of low contrast, small size, continuously moving target, and the complex background sc ene, the symmetry difference operation was done in the three frames of image sequences to guarantee the probability of target detecting and probability of false alarming required by the system and real-time imp lementation of hardwares. The software and hardware implementing princ iple of this algorithm was offered, and the analysis of real-time proc essing was given.
