blurriness

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。

To some degree this blurriness is inevitable .

从某种程度上讲，这样的模糊不可避免。

It is a good idea to blur the environment map to simulate the blurriness of a reflection .
