Through calculating the average energy of each column of DCT coefficients of the different blurriness image to get vector Ceng, we realize that Ceng of different blurriness images almost has no difference on the head end, and has obvious difference on the tail end.

  • 通过计算不同模糊程度图像的DCT系数每列的平均能量得到向量Ceng,发现不同模糊程度Ceng向量的首端分布几乎没有差别,而尾端分布具有明显差别。
