Resumen:
Nowadays consumers of worldwide can capture digital image and video
scene using several multimedia devices such as smartphones, tablets and
cameras. Thus, the data captured may be easily copied or transmitted
without any control and as consequence the intellectual property of the
owner can be infringed, causing economic or moral damages. This fact
suggests the necessity to develop security tools such as watermarking,
to confront problems associated with the copyright protection. In this
paper we propose an improved unseen-visible watermarking algorithm for
copyright protection of digital color images. Unseen-visible
watermarking is a recent approach that takes advantages of the visible
and invisible watermarking, such as the readability and imperceptibility
respectively, preserving the robustness of both. The design of the
proposed method is based on Just Noticeable Difference (JND), Total
Variation-based image decomposition and an image enhancement criterion.
The watermark can be readable with a naked eye through the manipulation
of image enhancement of the display device. Experimental results show
that the scheme is effective for digital color images, preserving a high
imperceptibility and its computational complexity is low.
