Comments on 'new family of lapped biorthogonal transform via lifting steps'
An unaddressed problem with Cheng's design is pointed out from the filter viewpoint: the first few basis functions do not decay smoothly to zero at the end, which may increase blocking artefacts, especially at low bit rates.
