摘要

•The IWT, which keeps the coefficients as integers, makes the join operation possible.•Join operation uses statistical data instead of each coefficient to compute the value of GCV.•An iterative GCV is proposed to reduce complexity of acquiring the GCV threshold.•Fast translation invariant is applied to reduce ringing effect of singularities.
