hi sir..
I have a project in Digital Image Processing.
My project title is : Robust DWT-SVD Domain Image Watermarking.
I have a problem. after applying SVD to cover image and the visual watermark, I have no idea hoe to modify the singular values of the cover image in each subband with the singular values of the visual watermark
Thank you.
i have a project (Robust DWT-SVD Domain Image Watermarking:
Embedding Data in All Frequencies).
i use DWT, decompose the cover image A into 4 subbands:
LL, HL, LH, and HH.
can you tell me how to apply svd to each subband imageā¦
the program uses matlab. thx
