[Retracted] A Robust Image Encrypted Watermarking Technique for Neurodegenerative Disorder Diagnosis and Its Applications
Algorithm 2
Extraction of the watermark.
1 Start | 2 Perform Layer Separation | 3 Convert Watermarked Image to GBT Transform | 4 Apply SVD on each layer of W’(m,n). | 5 Decompose to get S value of W’(m,n). | 6 Extract watermark using equation (18). | 7 Extract S value of w(m,n). | 8 Implement Inverse SVD for the combination of S values. | 9 Implement the process of Inverse GBT Transform of watermarked data. | 10 Use the image decryption formula to separate watermark and watermarked images. | 11 End |
