摘要： As set forth herein, computer-implemented methods and systems facilitate watermarking documents and/or images using 2nd generation stochastic halftoning. The watermark is used to spatially vary the gray level at which a frequency modulation-to-amplitude modulation transition occurs. The encoding algorithm uses as inputs a contone image and a watermark. The visibility of the watermark is controlled by the magnitude of the difference between the AM-to-FM transition threshold values.

摘要： A system and method for halftoning for multi-pass rendering of an image in which different pixel locations are rendered in each pass which reduces the effects of inter-pass mis-registration errors. The method of halftoning includes restricting a substantial majority of the pixels turned on to render a tone to the minimum number of passes required to produce the tone. The halftoning method can include generating a stochastic halftone turn-on sequence and re-ordering the turn-on sequence. The halftoning method can also use error diffusion, adding a zero mean bias signal to either the image input pixels or the threshold values. The halftoning method is applicable to color or black and white rendering.

摘要： A system for generating a security mark includes a data reception component that receives information. A security mark generation component in communication with the data reception component generates at least one security mark configuration based at least in part upon the received information. The at least one security mark configuration includes at least one simulation mark which resembles a natural feature. An application component applies one configuration of the at least one security mark configurations to a recipient. The applied security mark configuration obeys at least one rule whereby the security mark is distinguishable from the natural feature which it resembles by a system for detection of security marks.

摘要： Patterns are aligned on the front and back surfaces of a document to provide an anti-counterfeiting security device. The document is sufficiently transparent to allow see-through of the partial image on the back of the document to be superimposed on the partial image on the front of the document to form a complete image if the patterns are properly aligned. The complete image will disappear if misaligned.

摘要： By using negative feedback, moiré patterns can be reduced, or virtually eliminated, from input black-and-white or color original images. In particular, by feeding back an image containing the difference between the original input image and the halftone output with possible moiré patterns, and subtracting the low-frequency part of this image from the original input image, a resultant halftone image can be achieved that has reduced moiré patterns.

摘要： A method of quantizing pixels from a first pixel depth to a second includes adding to an original value of each pixel to be quantized, an error value resulting from quantization of any previous pixels, to generate a modified pixel value; comparing each modified pixel with threshold varying in accordance with the gray difference that a printed mark would make to a neighborhood pixels and outputting second depth pixels responsive to said comparison; and determining a halftoning error as a function of the modified pixel values, the gray difference, and the binary signals, and distributing say error to other gray level pixels in an image.

摘要： A grayscale two-dimensional barcode may be converted to a two-dimensional color barcode. The color barcode includes a set of sub-regions, and the cells in each sub-region exhibits a color pattern that corresponds to pattern of binary, grayscale cells. The two-dimensional color barcode may be decoded by comparing the pattern for each sub-region to a known grayscale pattern. The two-dimensional color barcode may be used for error correction by first decoding the barcode in grayscale form based on the luminance without reference to color, then decoding the barcode based on its color and comparing the results.
