20090268218 | HYPOCHROMATIC IMAGING - Color management constraints on the use of selected hypocolorant(s) and a black colorant in the rendering of a given pixel reduce ink or toner usage and/or reduce pressure on an ink limit. Additionally, the enforcement of this mutual exclusivity between the black and the selected hypocolorant(s) allows screen frequencies and angles to be shared between halftone screens used for the black colorant and a selected hypocolorant. This reduces the likelihood of objectionable moiré associated with the use of hypocolorant colorants in addition to the conventional CMY(K) colorants. In some embodiments, color management constraints prevent the use of black colorant for pixels beyond a threshold lightness or luminance. This constraint allows the use of the selected hypocolorants in the region of color space beyond the threshold. The threshold can be a function of hue and/or chroma. In some embodiments the threshold is a constant. | 10-29-2009 |
20100119158 | POSITIONAL DISTORTION COMPENSATION - A de-warp map is generated by applying principal component analysis (PCA) to vectors describing aspects of identified features of an object in an image. PCA provides vectors and coefficients describing curvature or image warping at selected points in the image. Estimates of the warping of the image generally are generated by interpolation and/or extrapolation from the vectors and coefficients provided by PCA. In some applications only two features need be identified. For example, the complicated curvature of the facing pages of an open book can be characterized by two vectors describing positions of top and bottom edges of the book. In such applications PCA can reduce to vector subtraction to determine a basis vector, vector addition and scaling to determine an average vector and simple assignment of known coefficient values. The de-warping map can be used to generate a de-warped version of the image. | 05-13-2010 |

20100189348 | SPOT COLOR TABLE COMPENSATION - Spot color tables, or spot color emulation colorant recipes are updated using information generated during a first and second process color related system calibration. Rather than separately calibrate, through trial and error, individual spot color emulation colorant recipes, information from the first and second general system calibrations is used to adjust spot color recipes. In one embodiment, processing an existing or initial spot color recipe through both a first system model and a second system model generates a device independent color difference. A colorant difference is then determined by transforming a predicted color difference according to estimated partial derivatives of aspects of the second system model, wherein the partial derivatives relate changes in colorant amounts to changes in parameter values of a machine independent color space. | 07-29-2010 |

20110273730 | PROCESSING IMAGES TO BE BLENDED WITH REFLECTED IMAGES - Images are prepared for blending with a reflection. Angles of incidence and angles or reflection lead to reflections of a viewer appearing to be different than actual size. Accordingly, image preparation can include scaling images of objects to be blended with a reflection to an appropriate size. For a flat specular surface the size is one half the size the object would be if the object were sized to be associated with the feature that is reflected.

In one example embodiment, a spot color of interest is selected along with a set of image quality attributes to be improved for the spot colors of interest. Set points for process actuators and color recipes of the color marking device are adjusted such that a function of the image quality attributes is minimized when the spot color is rendered on the device.

20130132166 | SMART TOLL NETWORK FOR IMPROVING PERFORMANCE OF VEHICLE IDENTIFICATION SYSTEMS - A smart toll network system for “network-based” analysis via communication of relevant vehicle identifications among to stations (i.e., by forming a smart toll network) coupled with a probabilistic-based search is disclosed. Comparing vehicle identification data (such as license plate recognition and vehicle signatures) between toll stations improves the performance relative to point-based vehicle identification analysis. Of the vehicles unidentified by license plate recognition, vehicle signatures are used to link each of them to the corresponding vehicle at the opposite end of the tolling system. If license plate recognition fails on a vehicle at an exit station, vehicle signatures can be used to find the location where that vehicle entered the tolling system. If license plate recognition was successful at the entrance station, that same license plate number can be assigned to that vehicle at the exit station, on the basis of the vehicle signature matching, without requiring human intervention. | 05-23-2013 |

A candidate sub-image is identified within the captured image. A cumulative histogram is formed using the reflectance values of each pixel in the candidate region. A threshold reflectance value is then determined from the cumulative histogram using a pre-defined cumulative occurrence fraction value which corresponds to a value equivalent to an average sized human face. Embodiments for setting the threshold reflectance value are disclosed. Thereafter, human occupants can be distinguished in the image from the vehicle's interior by comparing pixel reflectances in the sub-image against the threshold reflectance value. | 06-06-2013 |
