The notion of security of watermarking methods has recently attracted the interest of the watermarking community. An equivocation equal to zero corresponds to exact knowledge of the key. users cannot detect or remove the watermark should be based solely on their lack of knowledge of the correct keys.. As implied by their name, removal attacks result in the removal of...

The algorithm detects the regions of the image that are altered/unaltered and, thus, are considered nonau- thentic/authentic, respectively. The alterations that are produced by a relatively mild compression and do not change significantly the quality of the image are also detected.. The framework allows authentication of the watermarked images before recovery of the original image. Effectiveness of the framework is...

The outcome of the matching process is defined by a matching score. The results of performance evaluation of the fingerprint matching algorithm are illustrated in Fig. 24.1 INTRODUCTION. Over the past decade, the problem of face recognition has attracted substantial attention from various disciplines and has witnessed a skyrocketing growth of the literature. Below, we mainly emphasize some key perspectives...

Hence, we propose shape variation models for each of the age groups that best account for the factors that induce such variations.. 1 ) denote the angular coordinates of a point on the surface of the object before and after the transformation. Face anthropometry: of the 57 facial landmarks defined in [83], we choose 24 landmarks illus- trated above for...

Optical defocus can be fully described as a phenomenon of the 2D Fourier domain. Gross anatomy and embryology of the eye. 26.1 INTRODUCTION. are described in Sections 26.3–26.5. In Section 26.6 we describe the class of “iterative methods” that are based on a finite dimensional discretization of the problem. 26.2 BACKGROUND. 26.2.1 X-ray Computed Tomography. The concept of the line...

Example of cone-beam reconstructions from a circular orbit—the obvious artifacts are a result of the incompleteness in the data. are the coordinates on the detector of the cone-beam projection of x, see Fig. These artifacts are characteristic of the Feldkamp algorithm. Generally the artifacts manifested in the reconstructed images depend on the object being imaged and on its position relative...

27.4.2.1 Background Subtraction. In the process of subtracting (or dividing) one image by another, some of the dynamic range of the original data will be lost.. 27.4.2.2 Surface Fitting. is the spatial distribution and frequency of the sampled points. A least-squares fitting approach may then be used to determine the coefficients of the polynomial function. For a third-order polynomial, the...

822 CHAPTER 27 Computer-Assisted Microscopy. 27.6.5.1 Deblurring. It is often necessary to use only a small number, M , of adjacent planes to remove most of the defocused information. Figure 27.17 shows images from transmitted light microscopy and fluorescence microscopy that have been deblurred using optical sections above and below at a Z-interval of 1 m. FIGURE 27.17. 27.6...

p-Version of the XFEM. The black line indicates the asymptotic displacements of the crack surfaces in the vicinity of the crack tip. It can be seen from the figure that the approximation of the displacement field results in big differences to the analytical solution.. Furthermore a constriction is noticeable which occurs at the position where the crack cuts the edge...

The quantification is achieved by estimating the failure probability P f of the struc- ture. For problems in the scope of civil engineering, this probability depends on the random nature of the stress values S as well as the resistance values R , as depicted in Figure 4.103. General definition of the failure domain depending on scattering resis- tance (R)...

λ)-ES is the heart of the strategy and the most vigorous optimization force. In the most general case, the population-based model allows for an adaptive adjustment of the step lengthes of each corresponding optimization/design variable (called anisotropic mutative step length control). The following explanations clarify the effects of the equations above. Parent variables are the originators of the generation where...

Unfortunately, the image quality of a GIF file is quite poor. JPEG is a compression format that uses advanced algorithms to recalculate the image data and remove content that is not easily noticed by the human eye. JPEG compression can be excellent, but if you set the compression too high, the image can end up looking a bit like a...

You might remember from earlier in the hour that the Resample button becomes active only if you change the size of the image. Now you want to resample the image so that the picture in the image file is of the correct dimensions.
