根据不变矩特征的尺度变化规律,以及三层BP网络的结构特征,提出了基于多级BP网络模型目标识别的新方法。通过高斯金字塔模拟目标的多级尺度模型,利用不同级别的模型建立目标的多级BP网络模型。通过对3类飞机目标的大量仿真试验,这种基于多级BP网络模型的识别方法,能有效的完成多尺度目标识别,提高目标识别的正确率。
Through the study of rule of invariant moments and structure character of BP nets , a novel method of targets recognition based on multiple BP nets is proposed. In this paper, we simulate multi -scale models of targets through Gaussian pyramid, and then establish multiple BP nets of targets. Massive simulation experiments on three kinds of aircrafts prove that aeeuracy of targets reeognition is advanced through this novel method.
