Figure 1From: Computer-aided diagnosis of breast microcalcifications based on dual-tree complex wavelet transform Practical implementation of DT-CWT on 1-D signal. X stands for the input signal. h0 (n) and h1 (n) represent the low-pass and high-pass filter pair for the upper filter bank, g0 (n) and g 1 (n) represent the low-pass and high-pass filter pair for the lower filter bank, respectively.Back to article page
