[Retracted] A Robust Image Encrypted Watermarking Technique for Neurodegenerative Disorder Diagnosis and Its Applications
Algorithm 1
Watermark addition algorithm.
| Input: Selected Images | | Output: Watermarked Image | | Begin | | 1 Select the Images | | 2 Take the image watermark w(m,n). | | 3 Perform separation of RGB image layers M(m,n) and watermark w(m,n). | | 4 Use Hyperchaotic Encryption to encrypt w(m,n) | | 5 Use GBT Transform on every layer of M(m,n). | | 6 Extract the S value of the selected image and watermark. | | 7 Mix S value from selected image and watermark | | 8 Embed watermark w(m,n) to M(m,n) by taking α as 0.01 using equation (11). | | 9 Output modified S value. | | 10 Repeat steps from 1-9 till images are processed completely | | 11 End for | | 12 nd |
