Mean value PSNR, with respect to 300 images in the Berkeley data set, produced by 2D atomic decomposition of the arrays W{m} = 1, …, 300 in order to obtain SR = 20 (2nd and 6th column) and SR = 10 (4th and 8th column).

针对伯克利数据集（Berkeley Dataset）中的300幅图像，通过对数组W_m（m=1,2,…,300）执行二维原子分解，分别得到超分辨率（Super Resolution，SR）放大倍率为20（对应第2列与第6列）和10（对应第4列与第8列）的结果，由此计算得到的峰值信噪比（Peak Signal-to-Noise Ratio）平均值。
