“…Several studies have focused on watermarking based on the Fourier transformation [1], [6], [10]. Solanki et al [10] have investigated the effect of the print-scan operation on the coefficients of the Fourier transform magnitude; they concluded that the middle and low frequency coefficients are better preserved than the high frequency ones.…”

“…Solanki et al [10] have investigated the effect of the print-scan operation on the coefficients of the Fourier transform magnitude; they concluded that the middle and low frequency coefficients are better preserved than the high frequency ones. If the watermark is inserted in the low frequency coefficients, there occurs a significant distortion of the image.…”

The print-scan operation is still challenging in the watermarking community, some watermarking techniques were proposed in the literature to deal with this operation. These watermarking techniques are still very sensitive to degradations produced by the print-scan process. This paper investigates a watermarking technique in the Fourier domain that is robust to degradation produced when an image is printed in physical support then rescanned. The watermark is embedded in a middle frequency band of the discrete Fourier transform of an image using the improved spread spectrum technique. Some image restoration techniques were implemented. They were tested on images which were watermarked, printed and then rescanned before the watermark extraction. Experimental results clearly show the advantage of using the proposed approach.

“…Estimation of the lighting distortion parameters can be performed in a number of different ways, but this topic is not the focus of this work. In reality, barcodes signals that have been printed and re-imaged in motion are modified by a plurality of degradations including optical blur, noise, and geometric distortions [11]. The criteria chosen to estimate the optimal blur operator, however, does not depend explicitly on these parameters so they are ignored.…”

quality assurance, blur estimation, structured printing, functional imaging, barcodesIn high-speed printed media inspection environments, image restoration pipelines play a critical role in establishing and continually evaluating performance. A key role of such systems is to understand, mitigate (and possibly remove) artifacts introduced by motion blur. An approach is proposed that uses barcodes to help calibrate a one-dimensional blur restoration pipeline. Techniques are demonstrated whereby the structure of barcode markings may be leveraged to estimate motion blur parameters, even under extreme blur conditions or when the barcode is unknown. In addition, a framework for comparing blur estimation procedures based on barcode readability is introduced. These techniques can be applied independently of one another, but together form a set of useful tools for blur restoration pipeline calibration. Within this framework, it is shown that a low-complexity blur estimation strategy demonstrates performance competitive with state-of-the-art approaches in term of speed and accuracy.Presented at IEEE International Conference on Image Processing, Hong Kong, China, September 26-29, 2010Copyright IEEE International Conference on Image Processing, 2010 BARCODE-BASED CALIBRATION OF A 1-D BLUR RESTORATION PIPELINE Matthew D.

“…Addressing these sources of distortion either by prior modelling or posterior compensation would in general increase the overall robustness of hidden data. 4 Another important challenge is the printed image quality and watermark imperceptibility. The embedded data should normally be visually imperceptible, and the visual quality of the watermarked printed image should be very close, ideally identical, to the quality of the non-watermarked printed image.…”

Abstract. In this article, we propose a joint halftoning and data hiding technique for color images. To ensure high quality of the printed image, the color direct binary search (CDBS) iterative halftoning algorithm is used. The proposed approach uses the commonly available cyan, magenta and yellow colorants to hide data in the chrominance channels. Orientation modulation is used for data embedding during the iterative CDBS halftoning stage. The detector is using PCA-learned components to extract the embedded data from the scanned image. Experimental results show that this proposed CDBS-based data hiding method offers both higher data hiding capacity and higher robustness to the print-and-scan channel when compared to the state-of-the-art grayscale counterpart method. The relatively high correct detection rate make this approach suitable for applications which require exact extraction of embedded data in prints.
