Adaptive Wavelet Thresholding Algorithm Based On Subband Noise

ZHONG Hua~(1,3), ZOU Dao-wen~2, DENG Chen-zhi~1, WANG Sheng-qian~1 (1. Key Laboratory of Photoelectron & Communication, Jiangxi Normal University, Nanchang 330027;2. Department of applied physics, Jiangxi Science & Technology Normal University, Nanchang 330013; 3. Physics and Communication College, Jiangxi Normal University, Nanchang 330027)  
In this paper the author proposed a new method of wavelet threshold.This method is obtained by impkaing traditional Donoho threshold.But traditional threshold doesn`t consider the difference of noise in different subband, and use the only threshold to all wavelet coefficients.Obviously,the old onc is not reasonable. So the author proposed an adaptive wavelet threshold which changes with the noise in subband,which is proned that the result is satisfying.
