Abstract
To solve the problem of scanning method and vector method that antinoise ability is not strong
extraction precision is not high
an improved approach for star extraction from star image is proposed
by introducing region growth algorithm. The proposed method establishes rules of similarity to judge and extract star targets
according to characteristics of strong correlation that star targets have. The simulation results show that the proposed method has strong antinoise ability and high extraction precision.
