25 Sep 2009	Image segmentation & Extraction This program segments and extracts objects from an image. Author: Jeny Rajan	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.
03 Sep 2009	Simple SVD SVD computation using QR decomposition Author: Paul Godfrey	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 image… the program uses matlab. thx
