Image Compression and Watermarking scheme using Scalar Quantization
This paper presents a new compression technique and image watermarking algorithm based on Contourlet Transform (CT). For image compression, an energy based quantization is used. Scalar quantization is explored for image watermarking. Double filter bank structure is used in CT. The Laplacian Pyramid (LP) is used to capture the point discontinuities, and then followed by a Directional Filter Bank...
متن کاملAmodified Image Watermarking Using Scalar Quantization in Wavelet Domain
A quantization based method for watermarking digital images is presented here. This scheme inserting a watermark bit into wavelet coefficients of high magnitude (LH3-HL3). Also, this watermarking technique is blind (i.e., neither the original image nor any side information is required in the recovery process) as well as being very computationally efficient. This watermarking algorithm combines ...
متن کاملFragile Watermarking Scheme for Accepting Image Compression
As images are commonly transmitted or stored in compressed form such as JPEG lossy compression, image authentication demands techniques that can distinguish incidental modifications (e.g., compression) from malicious ones. In this paper, we propose an effective technique for image authentication which can prevent malicious manipulations but allow JPEG compression. An image is divided into block...
متن کاملA joint JPEG2000 compression and watermarking system using a TCQ-based quantization scheme
In this paper, we describe a Trellis Coded Quantization (TCQ)-based quantization and watermarking technique in the framework of JPEG2000 still image compression. Furthermore, we investigate the design of a novel joint compression and watermarking scheme based on a hybrid TCQ module which can perform at the same time quantization and watermark embedding. The watermark extraction process can be a...
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...
