Abstract

Abstract:

For computer video radiation signal of low SNR, denoising is necessary for restoring video signal accurately. Based on the basic structure of lifting wavelet

algorithm, the denoising algorithm of multiadaptive lifting wavelet is proposed. In the operations of predicting, updating, and threshold denoising, the adaptive factors are

added. The algorithm of traditional denoising， lifting wavelet denoising, and multiadaptive lifting wavelet denoising are used to deal with the computer video radiation

signal of low SNR, the results show that the effect of multiadaptive lifting wavelet denoising algorithm is better than others.

Key words: computer videointercepting, denoising, multiadaptive, lifting wavelet transform, threshold
