    Abstract: In embedding a watermark, it is possible to effectively detect the watermark even in case of rotating, cutting, and enlarging/shrinking an image by designing the watermark to be robust against geometric modification and embedding the watermark as 2-dimensional form, for example radial or concentric form. Also, in detecting a watermark, it is possible to detect a peak formed by the watermark through the convolution of the watermark and an input image while accommodating a size of the generated watermark, thereby effectively detecting the watermark using correlation between the input image and the watermark.

    Abstract: Techniques and mechanisms are provided for facilitating the capture and review of visual images by visually impaired users. In one implementation, these techniques and mechanisms provide pre image capture functionality and captured image review functionality. With the pre image capture functionality, audio messages are provided to the user to help the user position an image capturing mechanism properly to capture the desired subjects in a picture, to frame the subjects properly within the picture, to size the subjects properly within the picture, etc. With the image review functionality, audio messages are provided to the user to help the user enjoy and "visualize" a visual image that has been captured and is being displayed to the user. With these functionalities, a visually impaired user is able capture and review images to a much greater degree than is currently possible.

    Abstract: The present invention proposes a method for generating a security bi-level image used to form one of the inks of a banknote, said image comprising an original bi-level image and a security pattern, said security pattern being obtained in the spatial domain by the inverse Fourier transform of the combination in the frequency domain between the Fourier transform of an auxiliary image and a two-dimensional sweep, said two-dimensional sweep being a circularly symmetric, two-dimensional pattern created by sweeping a self-similar, one-dimensional function along a 360-degree arc, such as said security pattern being detectable from the maximum value of the cross- correlation of said one-dimensional function with the Fourier transform of one line of said banknote, said method comprising the step of: -determining a distance map of the original bi-level image, -generating a merged image by linearly interpolating at least a part of said distance map with said security pattern, -thresholding the merged image to obtain the security bi-level image, -applying the security bi-level image on a support.

    Abstract: Metadata associated with a digital content record is modified, where the digital content record is to be provided to a particular recipient, and has associated therewith an account. A recipient list associated with the account identifies one of three or more metadata detail levels associated with each of a plurality of potential recipients. In this regard, a particular metadata detail level is determined based at least upon a comparison of the particular recipient and the recipient list. Then, the metadata associated with the digital content record is adjusted in accordance with the particular metadata detail level. Accordingly, a relative detail, or resolution, of information provided by the metadata may be controlled.
