Abstract :
In this paper, we propose an iterative optimization method using the statistical method. First, the method optimizes the prediction coefficients and then optimizes the update coefficients. To determine both the coefficients and the filter length of the wavelet transform, we introduce an iterative optimization. The proposed method gives the optimal lifting coefficients faster than other methods.
