【摘要】 对有限灰阶的增量算法进行了进一步的研究和改进，提出用边缘增强的训练样本代替普通样本模式进行互连权重的学习．通过对边缘增强的４种飞行器平面内旋转投影图的识别，证明此方法可使神经网络互连权重的灰阶数目进一步降低，从而更易于光学硬件实现更多还原

【Abstract】 The increment algorithm with limited gray-levels is improved. The training set with edge enhancement is proposed to calculate the interconnection weights. The recognition results for four kinds of aircrafts with edge enhancement, which rotate in plane, indicate that this method can reduce the gray-levels of the interconnection weights further and is suitable for optical implementation.更多还原
