Hello, I'm working on image watermarking, I'm working with DWT and SVD and I want to embed a watermark in some coefficients that changing in them wont destroy the quality of the image, do you have any idea how? should I use the edge detector for this or selecting the ROI of the image? I'm a bit confused!

Thank you in advance
