Abstract:
Digital Watermarking has emerged as a new area of research in an attempt to prevent illegal copying and duplication. In this paper, I represent both methods i.e. DCT&DWT based algorithm for watermarking in digital images. In order to compare the imperceptibility & robustness of the both algorithms make use of simple attacks such as resizing, rotation &cropping.
