An Image De-Noising Method Using Directions of Wavelet Decomposition Sub-Bands
Abstract:
In this paper, an image de-noising method using directions of wavelet decomposition sub-bands is proposed. Wavelet coefficients are correlated in a small area, and the wavelet transform uses wavelet coefficients in three directions to describe image information, so in each sub-band the proposed method only calculates neighboring wavelet coefficients in a certain direction rather than in eight directions. Compared with other wavelet de-noising methods, the proposed method can achieve higher peak signal to noise ratio.
