HL and HHby GHM multi-wavelet.The edges of LL(with the highest important degree) and HH(with the lowest important degree) are detected by strong Canny method.With many thin edges
which are useless for medical diagnosis
patientsinformation can be hid by deletion and comparison processing of invalid edges.Edges of medical images are modified in order to embed patientsinformation
so the privacy can be protected under the normal visualization and the existing diagnosis information of patients can be carried safely.
