摘要： A method of generating a dither matrix for an output device having sub-pixel addressability that permits the attenuation of tone for less than whole pixels. An original representative pixel grid is expanded to a super-resolution by replication of the pixel grid in both directions by the sub-pixel factor S. Halftoning methods for generating dither patterns are then applied using the super-resolution grid to create dither or filter outputs, which are converted to a corresponding output for a sub-pixel resolution grid. Selection of location for incremental addition (deletion) of tone is made using the sub-pixel grid output. The cycle of output generation, conversion to sub-pixel resolution, and tone modulation selection is repeated iteratively until a desired gray level is reached. The process is further repeated for each desired gray level to produce the multiple dither patterns that comprise the desired dither matrix.

摘要： A system and method for embedding information within an input image utilizes specific type pixel blocks of the input image to selectively embed the information into the input image. The information is embedded into the input image by replacing the specific type pixel blocks with predefined dot shape blocks, which represent the information to be embedded. In an embodiment, the specific type pixel blocks are minority pixel blocks, which include a majority of pixels that contrast with the image background. The use of minority pixel blocks makes the embedded information less perceptible in the final image. In an embodiment, error diffusion is performed on a pixel block by pixel block basis so that the final image with the embedded information is of high quality and more suitable for printing on laser printers.

摘要： A method of using error diffusion to generate a halftone image for an output device having capabilities to attenuate or modulate tone at a sub-pixel level. A lookup table is created, indexed based on possible exposure characteristics of pixels neighboring the pixel currently being processed. The lookup table, so indexed, outputs allowable exposure configurations for the pixel currently being processed, which allowable configurations are consequent to sub-pixel modulation capabilities of the output device. An exposure configuration is selected from the allowable configurations by comparison of a modified input value for the current pixel to the allowable configurations. The selected exposure configuration is then applied, and the modified input value and exposure value are differenced to generate a new error value to propagate forward in the error diffusion process. The process is repeated sequentially for each pixel according to the error diffusion technique employed.

摘要： Systems and methods of estimating motion for compressing multiple view images are described. In accordance with a machine-implemented method of encoding a target image of a scene captured at a first image plane, a transformation is computed. The transformation maps at least three noncollinear points substantially coplanar on a scene plane in the target image to corresponding points in a references image of the scene captured at a second image plane different from the first image plane. At least one point in the target image off the scene plane and at least one corresponding point in the reference image are identified. A motion between the target image and the reference image is estimated based on the computed transformation and the identified corresponding off-scene-plane points. The target image is encoded based at least in part on the estimated motion.
