Color in Image Watermarking
In the last decade, we have seen a tremendous growth in color and color-based applications within the signal, image and video processing communities. Color is no longer interpreted as an extension of gray scale and is now considered as a key element for a number of image and video processing systems. In particular, color space transforms have played a central role in coding, compression and tra...
متن کاملA New Shearlet Framework for Image Denoising
Traditional noise removal methods like Non-Local Means create spurious boundaries inside regular zones. Visushrink removes too many coefficients and yields recovered images that are overly smoothed. In Bayesshrink method, sharp features are preserved. However, PSNR (Peak Signal-to-Noise Ratio) is considerably low. BLS-GSM generates some discontinuous information during the course of denoising a...
متن کامل2DKLT-based Color Image Watermarking
The paper presents a digital image watermarking algorithm realized by means of two-dimensional Karhunen-Loeve Transform (2DKLT). The information embedding is performed in the two-dimensional spectrum of KLT. Employed two-dimensional approach is superior to standard, one-dimensional KLT, since it represents images respecting their spatial properties, resulting in a lower noise and better adaptat...
متن کاملA New Color Image Watermarking Scheme
A new spatial domain probability based watermarking scheme for color Images is proposed. The blue channel of the color image has been used for watermark embedding. Host image is divided into 8x8 blocks and each bit of the binary encoded watermark is embedded in each such block. For each inserted bit, intensity of all the pixels in the block is modified according to the embedding algorithm. Non-...
متن کاملA color image watermarking scheme based on color quantization
Digital watermarking has been widely applied to solve copyright protection problems of digital media relating to illegal use or distribution. In the past few years, several gray-level image watermarking schemes have been proposed, but their application to color image watermarking schemes is scarce and usually works on the luminance or individual color channel. In this paper, a new color image w...
