摘要:
A method of achieving process-direction sub-raster magnification adjustment using non-redundant overwriting. The raster imager provides overwriting while the image path provides non-redundant data for each pass according to the desired magnification adjustment. The same laser power level can be used for the multiple writes, or optionally, it may be varied to further improve spatial resolution of the adjustment.

Disclosed are FIFO type methods, systems and apparatus for electronically registering image data relative to a raster or other marking device. According to an exemplary method, a FIFO type data queuing configuration is provided, where the length of data memory segments associated with the FIFO are selected to correspond to the number of raster lines from the most upstream point of the physical raster to the point where the given pixel column intersects the physical raster.

Sub-raster registration errors are compensated for through non-redundant overwriting. Data from adjacent rasters is written to a particular output raster so that the adjacent rasters share an influence at a point actually written to by a rendering device, thereby compensating for a sub-raster component of a registration error associated with writing to the particular point. If two writing passes per raster are used and the writing passes have equal influence (e.g., are written with equal power), then writing data from a first raster during a first pass and writing data from a second raster adjacent to the first raster during a second pass compensates for a sub-raster registration error of half a raster spacing. If two writing passes are associated with different influence (e.g., are written with ⅓ and ⅔ power respectively) and/or if additional writing passes are used, then addition sub-raster positions can be compensated for or emulated.

Disclosed are FIFO type methods, systems and apparatus for electronically registering image data relative to a rastering device or other marking device. According to an exemplary method, a FIFO type data queuing configuration is provided, where the length of data memory segments associated with the FIFO are a function of a spatial profile associated with the ink jet rastering device.

Methods and systems for discriminating between tires. One or more images of an unknown tire are received. One or more tread features are extracted from the images. The class of the unknown tire is determined using a classifier that matches the tread features to known tread features.

Provided are methods, apparatus and systems related to watermark decoding via spectral analysis of an image. According to one exemplary method, spectral analysis is performed to decode a watermark within an image, where the pixel spacing associated with the image was modulated to encode the watermark.
