摘要
提出了一种应用于体全息景象匹配系统中的多样本并行估计方法,该方法充分利用了遥感图像的平稳随机性和体全息的高速多通道并行性,可有效提高景象匹配的精度。分析了多样本并行估计方法的理论基础,研究了该方法所包括的图像预处理,模板图像制备以及估计方程建立等步骤,同时也研究了多样本并行估计过程对各步骤的要求。实验结果表明多样本并行估计方法可以有效提高景象匹配的精度,同时识别精度也会随着样本数的增加而提高。
Abstract
A multi-sample parallel estimation method using in the volume-holographic scene matching system is proposed. The method makes good use of the characteristics of stationary random of the remote sensing image and the characteristics of the high speed, multi-channel and high parallelism of the volume holographic correlator, and implements scene matching with high accuracy. Theoretical basement of multi-sample parallel estimation method is analyzed. The essential steps of the method including image preprocessing, template images preparation and estimation equation establishing are discussed in detail and the requirements for these steps are introduced. The experimental results show the validity of the multi-sample parallel estimation method, and the recognition accuracy is improved by increasing the sample numbers.
