| Abstract: | This paper introduces the wavelet frame, the decomposition and reconstruction algo-rithm of wavelet frame,and the threshold denoising algorithm of wavelet frame. We have con-ducted denoising experiment with the Haar wavelet, db4 wavelet, sym8 wavelet, and wavelet frame respectively. The simulation result shows that the denoising effect of minimum energy wavelet frame is better than that of Haar wavelet,db4 wavelet,and sym8 wavelet respectively. |
