FILTERING BASED ON WAVELET TRANSFORM

Wavelet transform (WT) is drawing enthusiasm from many disciplines and has made a lot of achievement. In this paper we study its application to filtering. According to different type of noise, the corresponding filtering algorithm is proposed based on different WT. Furthermore its principle is investigated. The simulation results indicate that the proposed algorithm provides an effective way for filtering which is not only simple and applicable, but also can satisfy various requirements of filtering.
