Compressive sensing is a signal processing technique that takes advantage of signal sparseness in some domain. To use compressive sensing, a domain in which the signal is represented as a few significant coefficients should be defined. If the proper domain is identified as a set of basis vectors, the coefficients are the projections of the signal on the basis vectors. This is typically a transformation...
In this paper, we propose a practical scheme for copyright protection of images with the aid of EXIF metadata and error control codes. Application for robust watermarking is one of the major branches in digital rights management (DRM) systems and digital forensics. By use of robust watermarking, it generally alters selected coefficients in the transform domain to accomplish the embedding process....
In this paper, we propose an application of robust watermarking with the aid of EXIF metadata in digital images. Application for robust watermarking is one of the major branches in digital rights management (DRM) systems. Furthermore, implementation schemes for robust watermarking generally alter selected pixels in the spatial domain, or corresponding coefficients in the transform domain, to accomplish...
