摘要： A system and method for providing signature-based drive-through order tracking. An image with respect to a vehicle at a POS unit can be captured at an order point and a delivery point (e.g., a payment point and a pick-up point) utilizing an image capturing unit by detecting the presence of the vehicle at each point utilizing a vehicle presence sensor. The captured image can be processed in order to extract a small region of interest and can be reduced to a unique signature. The extracted signature of the vehicle at the order point can be stored into a database together with the corresponding order and the vehicle image. The signature extracted at the delivery point can be matched with the signature stored in the database. If a match is found, the order associated with the vehicle together with the images captured at the delivery point and the order point can be displayed in a user interface at the delivery point to ensure that the right order is delivered to a customer.

摘要： Disclosed herein are optimal or near optimal algorithms implemented as software tools that will allow the user/machine to identify optimal media out of the job set automatically. There are at least two main process steps to the exemplary embodiment. The first step involves the off-line characterization of the printing/image rendering system that will be used to extract the principal basis vectors from the experimental data. The second step involves the run-time mode, in which the pre-characterized basis vectors are used in conjunction with an optimal algorithm that will identify the media for re-calibration/re-characterization from the group of media set that the customer is interested to print. The optimal algorithm performs the combinatorial search every time the customer wishes to select the media. Once the optimal media is selected, the customer or the machine can print color patches (which are also optimal set) and execute the rest of the processing to reconstruct the best color management LUTs.

摘要： A show-through reduction method is disclosed. The method is designed to deal with both light and severe show-through. The method focuses mostly on text documents, with characters possibly appearing in multiple gray levels, although the method can also be extended to color documents. As in the prior art, the front and back pages are processed in pairs. However, no perfect page alignment is assumed here, since we are dealing with real images. Instead, a front and back registration is performed as the first step before the pages are further analyzed. In this method, we are aligning the front page content with its show-through appearing in the back side, and the back page content with its show-through appearing in the front side. Once the two sides are aligned, masks are generated for both sides to differentiate severe show-through and light color content regions. Finally, different TRCs are applied to different regions. The show-through is reduced and the page contents are retained.

摘要： What is disclosed is a system and method for diffusing pixel error in a halftoning process in a color management system. The present method divides a modified CMYK input into a real and imaginary portions. The real portion is the coverage achieved by a physically realizable positive dot. The imaginary portion comprises a an imaginary negative dot and an imaginary excess dot. Each of these dots are processed separately, on a per-pixel basis, in a novel CMYK to CMYKKpRGB conversion discussed in detail herein. Hierarchical thresholding is preformed on the conversion output to produce a high-quality halftone result. A cumulative pixel error sum is derived therefrom and combined with the input CMYK coverages of a next pixel. All pixels are processed. The halftone output generated hereby has the pixel error compensated. Other embodiments are provided.

摘要： A method and system is provided for segmenting scanned image data in accordance with mixed raster content processing for more efficient processing of non-uniform color page borders. A first processing method partitions the border so that resulting segments can be coded efficiently by cutting the border into segments along cut lines disposed in optimum position for minimizing a total area of bounding boxes for the page border segments. Another embodiment determines the color variance within the page border window and compares the variance against predetermined color variance threshold. A window width of the page border window is also determined and compared with a predetermined width threshold. When the variance and window widths are smaller than the thresholds, a uniform color is assigned to the non-uniform color page border and the border is coded in accordance with a foreground layer compression algorithm.

摘要： A method is disclosed for detection of miniature security mark configurations within documents and images, wherein the miniature security marks may include data marks or a combination of data marks and anchor marks. The method includes sub-sampling a received image, which is a digital representation possible recipient(s) of the miniature security marks, to generate a reduced-resolution image of the received image. Maximum/minimum points detection is performed and the maximum/minimum points are grouped into one or more clusters according to location distances between the maximum/minimum points. Group configuration is checked to match the clusters with a pre-defined template configuration. Shape verification is then performed to verify mark location and configuration between the reduced-resolution image and the received image.

摘要： The exemplary embodiment disclosed herein comprises several aspects of defining and using optimal color test patches for calibrating a printing system for various purposes (e.g., multi-media, gamut extension, drifting correction, etc.). One aspect is the creation and use of color patches where the color patches are selected optimally to result in minimum mean square error when those color patches are used to determine weights of a limited number of basis vectors that model the system (e.g., model the print engine response). A joint optimization technique is given as a method to select the optimal color test patches for calibration.

摘要： A method of removing ringing and blocking artifacts from a decompressed digital image. In one method, a background value of the digital image a background region and foreground regions is determined, and a threshold value is computed. A mapping of the digital image is then generated by thresholding the digital image based on the threshold value to produce a thresholded image, and enlarging the foreground regions of the thresholded image to form a map image. The mapping includes the background pixels of the map image. The background region of the decompressed digital image is then cleansed based on the mapping. In an alternate method, ringing artifacts are removed from a decompressed digital image based on a signal-to-noise ratio of the image. In yet another alternate embodiment, ringing artifacts are from a decompressed digital color image that includes a chrominance channel and a luminance channel. An alternate embodiment removes ringing and blocking artifacts.
