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.
