摘要:

将遗传算法用于图象中低信噪比点目标的检测。在分析了点目标及背景特点的基础上,设计了编码方案及遗传操作算子,提出了合格个体保留法。仿真结果表明应用此算法,可实现信噪比为2dB的点目标的检测与跟踪。

Abstract:

A new algorithm is proposed for tracking low observable point source targets of unknown position and velocity in a digital image sequence with genetic algorithms. Coding and genetic operation are designed for this problem. Eligible points retaining as a new genetic operation is proposed here. The simulation results show that it can detect and track targets with SNR 2dB efficiently.

Key words: detecting, tracking, dim point target, genetic algorithms
