Abstract: 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.

Abstract: 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.
