To determine origin-destination (OD) data for a transportation system, a processor may receiving passenger statistics collected from a set of data collection devices deployed throughout the transportation system. The processor developing a model representing passenger usage of a portion of the transportation system. The model comprises nodes that each represent a geographical area of the transportation network, and links that represent transportation routes that connect two nodes. The system determines link utilization rates for each of the links by applying the passenger statistics to the model, and it generates an observation report comprising an origin-destination matrix for at least the portion of the transportation system so that the origin-destination matrix comprises the determined link utilization rates.

A method for fulfillment of a kit includes a) generating a 3D virtual simulation of a kit using a computer animation tool in a kit fulfillment environment after receiving a kit request from a customer, the 3D virtual simulation formed using 3D virtual models of objects in the kit and reflecting a spatial layout of components packed in a receptacle, the 3D virtual simulation including an interactive animation that dynamically controls a visual rendering of the 3D virtual simulation in response to a user at a user device selectively manipulating the kit or an object; b) providing the customer with remote access to the 3D virtual simulation to use a remote user device to control the visual rendering for a review of the kit; and c) releasing the kit for production and fulfillment of the request after receiving an approval from the customer in conjunction with the review.

Method for fulfillment of kit and apparatus associated therewith

Methods and a system for an electronic device to allow for indicating a size or scale of a rendering in a three dimensional view. A virtual scene is displayed on a display with a work product that is rendered, such as a document or packaging request having a job ticket. The rendering is provided with a common object that is a three dimensional virtual object that relates size to the document or packaging for approval in the proofing process. A quick visual cue is therefore provided to visually convey a realistic scale in proportion to the product rendered three dimensionally.

Visual indication of document size in a virtual rendering

A method and system for providing a virtual rendering alert with respect to a rendering job page exception. A realistic virtual three-dimensional rendering model with respect to the rendering job can be rendered utilizing a virtual rendering unit. One or more multi-media aspects can be added with respect to an anomalous object in the rendering job to automatically identify a page exception in the rendering job. A list of objects associated with the rendering job can be activated within a scene based on a set of print policies and/or production cost structures at the discretion of a user. A virtual clue can also be presented along with the realistic virtual rendering model in order to provide additional information with respect to the object in the rendering job and thereby effectively identify the rendering job exception.

Method and system for providing virtual rendering alerts for rendering job page exceptions

A method and system for coordinating placement of an augmented reality/virtual world object(s) into a scene relative to position and orientation. The object(s) can be connected to an anchor point having an absolute location relative to the marker via a connector (e.g., spring-like connector) in such a way that the behavior of the object responds to a physical force and a collision which exists in the augmented reality scene. The connection between the virtual object and location of the marker permits the object to exactly track the marker when there are no real world collisions between the markers. The virtual objects can be displaced so the objects do not pass through one another when the real world markers come into a close spatial proximity and the corresponding virtual objects begin to collide.

The present invention is a method and apparatus for improving the appearance of electronic images, and more specifically, to the efficient use of template rotation within a template matching process to enhance such images. The invention reduces the number of entries that are stored in a look up table by eliminating identical patterns that differ only by the angle at which they are output. The appropriate templates are then rotated it by the required angle for output subsequent to their retrieval from the lookup table.

Method and apparatus for using rotatable templates within look-up tables to enhance image reproduction

The methods and apparatus of this invention model and reconstruct binarized images. A grayscale image is modeled using a template matching approach. Each binarized grayscale image value is characterized by a unique set of templates which are rotations of each other. The set of templates allows construction of a look-up table between patterns and grayscale values. The look-up table is provided with a limited number of entries. As a result, the number of entries in the look-up table is reduced. The look-up table thus obtained is used for reconstructing the original grayscale image from the binarized image. The generated image quality is good in comparison with conventional methods. The process may be applied to various halftoning processes including error-diffusion processes.

Method and apparatus for modeling and reconstruction of halftoned images

In a printer, a controller keeps track of the imager's operation. The original image is transferred into a continuous tone image by using a tone reproduction curve. That signal is encoded into gray pixel data by a halftoner. The pixel data contains the pixel location and the desired darkness of gray, i.e., amount of toner deposited. An imager uses the pixel data to generate the final halftoned image in a printer. A controller generates a feedback signal based on the printer's operation and the quality of the final halftoned image. The imager uses the feedback signal to modify the encoded gray pixel data in order to adjust the final halftoned image. The original coding of the image into gray pixel data is generic and does not depend on the characteristics of the printer being used. This invention reduces the computation of gray pixel data and allows the imager to be separate from the apparatus generating the gray pixel data.

Control of toner deposition in gray pixel halftone systems and color

A method and apparatus for automating the design of morphological or template-based filters for print quality enhancement. A plurality of different phase, but same resolution, subsampled images are generated from training documents. Statistical data derived therefrom is then employed in an automated process to generate filters. The filters may be used for resolution enhancement and/or conversion of bitmap images. Furthermore, the statistical data is used to produce filters that are intended to not only optimize image structure, but image density as well.

Image resolution conversion method that employs statistically generated

A gray pixel encoding scheme is used in combination with a halftoner and an imager to produce halftoned images. A halftoner and an imager can be totally separate because the gray pixel encoding allows the imager to decode them at any time. The encoded gray pixels require less bandwidth than explicit gray pixels and can be decoded by the imager in an optimal fashion for the characteristics of the specific printer being used. An imager produces a small partial pixel within a spot boundary. The subpixel produced is called a gray pixel. The gray pixel is allowed to grow from a zero width to a full spot width and is allowed to start anywhere within the spot. The pixel codes describe the starting positions of the gray pixels, the locations of the gray pixels within the spot, and the gray pixel width required. The imager uses the encoded gray pixel from the halftoner to produce a final halftoned image. The list of encoded pixels produced by the halftoner can be stored and used at a later time or sent through a network to a different imager to be printed out.

Gray pixel halftone encoder

A hybrid halftone cell selection method enables selection of gray levels in halftone printing algorithms to minimize the effects of noise resulting in nonuniformities, such as, for example, halftone banding. The method requires selection of hybrid halftone cells possessing structures wherein the total number of gray pixels are limited. The number of gray pixels having any given intermediate reflectance level in any halftone cell is also limited. The cell selection method thus reduces the number of TRC gray steps to some minimum required number by eliminating the most noise sensitive cells (i.e. those cells having the highest percentage of gray level pixels). The intermediate reflectance values of the gray pixels in the selected cells are then selected to produce uniform gray steps and reduce variability in the TRC.
