The main objective of developing an image watermarking technique is to satisfy both imperceptibility and robustness requirements. To achieve this objective, a hybrid image watermarking scheme based on discrete wavelet transform and singular value decomposition is proposed in this paper. In our approach, the edge information of an image is used to embed the(More)
Feature extraction and classification based digital water marking is new area of research in current privacy protection and copyright technique. In this area of research various authors used feature extraction technique such as wavelet transform function and for classification purpose used support vector machine. in the process of feature based water(More)
