  1. A new denoising method based on combining multi - scale product with wavelet shrinkage is presented

    摘要提出一種將相鄰尺度的小波系數乘積與小波相結合的信號去噪方法。
  2. 2 ) proposed a de - noise method based on wavelet packet coefficient shrinkage. the resolution of the method is finer than that of the method based on wavelet shrinkage in time domain and frequency domain

    2 )基於donoho值去噪方法,給出了一種時頻解析度更高的小波包分解系數的去噪方法。
  3. And then, the soft / hard threshold was used to shrink the wavelet coefficient of the signal and reconstruct the signal. the method can suppress pseudo - gibbs phenomena on the singularity points of signal produced by de - noise algorithm based on wavelet shrinkage

    此方法對含噪信號進行循環平移,利用軟值或硬值函數對含噪信號的小波分解系數進行操作,並重構信號,再進行反向的循環平移,能有效地抑制pseudo - gibbs現象。
  4. The numerical experiments show that the proposed method can significantly raise snr, decrease mse and preserve the shape of signal better than the original wavelet shrinkage method

    數值模擬表明,與小波方法相比,該方法在信噪比和均方差指標上都有明顯的提高,並能很好地保持信號的形狀。
  5. The dwt decomposes an image into a series of different scalesmaller images, then detail coefficients are enhanced based on threshold shrinkage filter, and obtains the enhanced image after inverse wavelet transform

    圖像經過小波分解后可以得到一系列不同尺度上的子帶圖像,在不同尺度的子帶圖像上進行基於濾波的細節系數增強,再進行小波重構,即可得到增強后的圖像。
