Abstract
The high frequency of the image pre-filtering and sampling can not be eliminated, whereby the power spectrum of the oscillation may cause aliasing, the sampling scheme proposed two standard blue noise pattern: step blue noise and single-peak blue noise, two blue noise sampling task performance in the image plane of the well, as can the other at least in the low frequency band sampling mode, and in the high frequency band may not cause aliasing because they are mapped to white noise more effectively. experimental results show that at low sampling rates model can effectively prevent aliasing structure, at a high sampling rate to perform equally well.
