Study and Analysis of Robust DWT SVD Domain based Digital Image Watermarking Technique using Matlab

Study and Analysis of Robust DWT-SVD Domain based Digital Image Watermarking Technique using Matlab Abstract: This paper presents a robust and blind digital image watermarking technique to achieve copyright protection. In order to protect copyright material from illegal duplication, various technologies have been developed, like key-based cryptographic technique, digital watermarking etc. In digital watermarking, a […]


Similarity Validation based Nonlocal Means Image De Noising

Similarity Validation based Nonlocal Means Image De-Noising Abstract: Nonlocal means is one of the well known and mostly used image denoising methods. The conventional nonlocal means approach uses weighted version of all patches in a search neighbourhood to denoise the center patch. However, this search neighbourhood can include some dissimilar patches. In this letter, we […]
