Improvement of Threshold Function Based on Wavelet De-noising
Yi Lingzhi, Xiao Weihong, Yu Wenxin & Wang Genping · Journal of Advances in Mathematics and Computer Science · 2016
Hard threshold function is discontinuity in the threshold point, and soft threshold function have a constant error between the estimated coefficient of wavelet and the original coefficient of wavelet. To solve this problem, an improved threshold function is presented, which is co...
