摘要： Systems and methods for generating graphical bar codes (i.e., images that contain inconspicuous graphical modulations that encode embedded information) by halftoning with embedded graphical encoding are described. In one aspect, a graphical bar code is generated by halftoning regions of an original image. The original image regions incorporate errors diffused among regions of the original image and computed based at least in part upon modulations in the graphical bar code corresponding to a graphical encoding of a message. In another aspect, a graphical bar code is decoded by generating a base image having halftone regions representative of an original image. Regions of the base image are compared probabilistically to a set of graphical code words to obtain a sequence of graphical code words corresponding to a graphical encoding of a message. The sequence of graphical code words is decoded to produce a decoded message.

摘要： Systems and methods of correcting one or more defect pixels in a source image are described. The source image is formed from a plurality of pixels each having a respective value. In one scheme, a defect pixel is corrected based upon curvature information computed from pixel values located near the defect pixel. In another scheme, a median pixel value is determined from values of pixels located near a defect pixel, and the defect pixel is corrected based upon the median pixel value.

摘要： Systems and methods of graphically demodulating a graphical bar code (i.e., an image that contains inconspicuous graphical modulations that encode information embedded in an original base image) are described. The graphical bar code may be graphically demodulated automatically without foreknowledge of the original unmodulated base image, but rather based upon a base image that is derived based upon intrinsic features of the graphical bar code.

摘要： Systems and methods for backlit scene detection are described. The method includes performing a pre-test on an electronic image to determine that the electronic image does not include a disqualifying characteristic. Next, the method includes performing a type test on the electronic image to determine an image type of the electronic image from a first set of predetermined backlit image types. Next the method includes performing a post test on the electronic image to determine that the image darkness density does not exceed a predetermined density. Finally, the method includes performing a second post test on the electronic image to determine that the electronic image is one of a second set of predetermined backlit image types or that the edge percentage of the electronic image exceeds a predetermined percentage.

摘要： The subject application is directed to a system and method for image facial detection employing skin tones. Image data comprised of a plurality of pixels encoded in at least a three dimensional component space is received and sub-sampled region data is generated from the received image data. A percentage of pixels having a low chroma value below a threshold value is then calculated and tested against a predetermined percentage threshold value. Each pixel is then classified in accordance with a skin tone model. Skin tone map data is then generated based on classification and a skin tone mask is output form the map data.

摘要： The subject application is directed to a system and method for artistic scene image detection. First, image data is received that is encoded in a multi-dimensional color space. From the received image data, histogram data is then calculated. Dominant spike regions in the calculated histogram data are then identified. An N-sum value is then calculated from the identified dominant spike regions in the calculated histogram data. Testing of the calculated N-sum value against a predetermined threshold value then occurs. The received image data is thereafter classified as an artistic scene, a tinted artistic scene, or a sepia tone range artistic scene according to the testing results.

摘要： Payment indicia generating schemes are described that enable users to customize the appearance of the payment indicium and to accommodate a wide variety of validation processing environments, while providing a substantial defense against fraudulent photocopy attack. In some embodiments, a corroborative digital token is generated from payment information, and a base image is modulated with a graphical encoding of the corroborative digital token to produce a payment indicium. In some embodiments, a payment indicium containing embedded payment information is rendered on a printing surface with a printing characteristic that degrades with photographic reproductions such that the embedded payment information is extractable from an original rendering of the payment indicium but is un-extractable from a photographic reproduction of an original rendering of the payment indicium. In some embodiments, payment information is encoded into a corroborative digital token based at least in part upon one or more variable encoding parameters, and a payment indicium containing the encoded payment information is rendered.

摘要： A piecewise polynomial interpolation scheme treats images as three-dimensional data in which the X and Y coordinates are the input image dimensions, and the Z coordinate is the intensity of the image. The three-dimensional data set is fitted by a surface, and a resampling process on the fitting surface provides interpolative data. A thresholding process applied on these interpolative data produces a final image output. Based on the interpolating scheme, each output pixel is a weighted average of its neighboring pixels, with weights determined by the type of the interpolant, its degree, and the desired scaling factor. The weights may be pre-calculated for fixed scaling factors, such that the convolution is accomplished by table lookup. Additionally, the resampling process may include a phase shifting to realign said sampling location with respect to an input image.
