正如在之前的图标中所示的，我们可以用实线来真实的描述那些在每层上出现的峰值。
As shown in earlier diagrams, we can visually illustrate those peaks on each tier with a solid line.
实验结果表明，算法复原出的人脸图像更接近于真实图像，具有更高的峰值信噪比。
The experimental results demonstrate that the results of the proposed method are closer to the real images, with a higher peak signal to noise ratio.
通过仿真实验结果及均方误差(MSE)和峰值信噪比(PSNR)两种评价准则说明了该算法的有效性和可行性。
The validity and feasibility of the algorithm is tested through a simulation experiment and two appraisal criterions-mean square error (MSE) and peak value signal to noise ratio (PSNR).
