摘要： What is disclosed is a system and method for encoding and decoding data in a color barcode pattern using dot orientation and color separability. The spectral (wavelength) characteristics of the CMY colorants, commonly used in digital printing, and those of RGB sensors are exploited to achieve high capacity data embedding rates in color barcodes. The present method embeds independent data in two different printer colorant channels using dot orientation modulation. In the print end, dots of two colorants occupy the same spatial region. At the detector end, by using the complementary sensor channels to estimate the colorant channels, data is recovered in each colorant channel. The method approximately doubles the capacity of encoding methods based upon a single colorant channel and enables embedding rates which match or exceed that of other hardcopy barcodes known in the arts. The method is robust against inter-separation misregistration with a small symbol error rate.

摘要翻译： 公开的是使用点取向和颜色分离来对彩色条形码图案中的数据进行编码和解码的系统和方法。 通常用于数字印刷的CMY着色剂和RGB传感器的光谱（波长）特性被利用来实现彩色条形码中的高容量数据嵌入率。 本方法使用点取向调制将独立数据嵌入两种不同的打印机着色剂通道。 在打印端，两个着色剂的点占据相同的空间区域。 在检测器端，通过使用互补传感器通道来估计着色剂通道，数据在每个着色剂通道中被回收。 该方法基于单个着色剂通道使编码方法的容量大大增加一倍，并且使嵌入速率匹配或超过本领域已知的其它硬拷贝条形码的嵌入速率。 该方法对于具有小的符号错误率的分离间对位失调是鲁棒的。

摘要： A method and system for automatically determining an optimal re-training interval for a fault diagnoser based on online monitoring of the performance of a classifier. The classifier generates a soft measure of membership in association with a class based on a training data. The output of the classifier can be utilized to assign a label to new data and then the members associated with each class can be clustered into one or more core members and potential outliers. A statistical measure can be utilized to determine if the distribution of the outliers is sufficiently different than the core members after enough outliers have been accumulated. If the outliers are different with respect to the core members, then the diagnoser can be re-trained; otherwise, the output of the classifier can be fed to the fault diagnoser.

摘要： A method and system for identifying print jobs that are repeats of a previously completed job utilizing an object level hash table. Received print jobs can be parsed into meaningful classes of objects and a table of hash values can be computed for objects in each class and for each print job. A synopsis comprising the table of hash values can be retained in a database along with the job specific settings. A newly encountered job can be then declared as a repeat of a previous job based on the hashes for the new job that match the hash values for the previous job stored in the database. The classes of objects are readily determinable in common document formats used for print job submission, such as PDF.

摘要： A method automatically determines a workflow for a print job via analysis of PDF documents is disclosed. A job synopsis comprising hashed information of a historical print job's document content along with a PDF document-level and object-level metadata and information about workflow nodes and parameters can be stored in a database. The job synopsis of a new incoming print job can then be compared to the historical print job synopses database. If the new print job matches the historical print job within a certain predefined similarity limit, then workflow and parameter information associated with the historical job can be utilized to augment an initial workflow for the incoming print job.

摘要： What is disclosed is a system and method for searching a repository of documents containing images using an image as a query. The present method enables the adjustment of a threshold level through a no-reference quality assessment of the query image which produces an estimated measure of quality for the image. For each image in each document in the repository, a distance is computed between a hash value of each image extracted from the document and the hash value of the query image. Documents are flagged as possible matches if the computed distance is less than the adjusted threshold. Documents flagged as a result of the search are retrieved and provided to the user. The present method can be used along or as an adjunct to text-based search techniques. Other embodiments are provided.

摘要： A system for generating one or more new hardcopy prints from an electronic file comprising original digital image data, wherein the new hardcopy print(s) match a legacy hardcopy previously generated from the original digital image data of the electronic file, even when the legacy hardcopy was printed from an “enhanced” or “tuned” version of the original image data. The original image data and scanner data derived by scanning the legacy hardcopy are used to identify corresponding areas of constant color in the original data and the legacy hardcopy. The corresponding color areas are represented in a colorimetric color space and the original data color values are adjusted to match the legacy hardcopy color values. The adjusted data are used to print a new hardcopy. The colorimetric color space conversion is completed using a plurality of different printing device assumptions, and the printing device assumption resulting in the smallest starting color difference between the original color values and legacy hardcopy color areas is used for the color matching process.
