摘要： Disclosed embodiments of the invention relate to analyzing document images, which contain positionally encoded information, such as a maze-pattern watermark, and labeling the images based on a degree to which the document's content, such as text, occludes the position-encoding information. Depending on the degree of such occlusion, it may not be possible to extract enough position-encoding bits from a camera-captured image of the document to determine the camera-captured image's location within the document. An analysis-and-labeling module receives, as input, image data output by an image-generation-and-capturing module and off-line training data; performs analysis-and-labeling processing; and outputs image-label information. The results of document-analysis-and-labeling processing may be used for efficiently determining a location of a camera-captured image within a positionally encoded document.

摘要： In accordance with embodiments of the invention, local metadata is embedded into an embedded interactive code document by combining a first m-array and a second m-array to generate a combined m-array with encoded local metadata such that a start position of the second m-array in the combined m-array is shifted, by an amount that is based on the local metadata, relative to a start position of the first m-array in the combined m-array. The first m-array and the second m-array may contain the same repeating bit sequence. Local metadata may be decoded from the embedded interactive code document by decoding the local metadata from the combined m-array by determining the amount by which the second m-array is shifted, relative to the first m-array, in the combined m-array.

摘要： In accordance with embodiments of the invention, local metadata is embedded into, and extracted from, an embedded interaction code document. A plurality of local-metadata values are assigned, in accordance with a set of local-metadata conflict-resolution rules, via a plurality of respective partial-share channels, to a plurality of respective local-metadata fields. The local metadata is decoded by decoding the partial-share channels and by resolving potentially conflicting decoded local-metadata values according to the set of local-metadata conflict-resolution rules. A local metadata value of a region to the left may be smaller than a local metadata value of a potentially conflicting region to the right, and the values may be non-continuous. A local metadata value of an upper region may be smaller than a local metadata value of a potentially conflicting lower region, and the values may be continuous.

摘要： At least one image captured from a printed document and at least one image captured from a display surface other than a printed document are processed. A surface-type-identification module accepts as input both types of images and identifies, for a particular image, the type of surface from which the image was captured. A display-surface-preprocessing module preprocesses the at least one embedded-interaction-code image captured from a display surface other than a printed document. A printed-document-preprocessing module preprocesses the at least one embedded-interaction-code images captured from a printed document. An embedded-interaction-code-processing module outputs location information for at least one of the at least one image captured from a printed document and the at least one image captured from a display surface other than a printed document.

摘要： Embodiments of the invention configure and analyze an embedded interaction code (EIC) array of an EIC document. An EIC font, having a selected geometric shape, is configured so that a generated EIC symbol encodes EIC data. The EIC font is configured with at least one orientation dot so that a captured image can be properly orientated. An EIC document system is configured to support a desired address space of an EIC array, a desired decoding performance, and a desired level of readability of an EIC document. An EIC font is configured to include a plurality of data dots along an edge. The selection of the EIC font takes into consideration a number of dimensions and the order of a constituent m-array, which is associated with one of the dimensions. An EIC font may be configured with at least one clock dot to support segmenting EIC symbols in the captured image.

摘要： Described is a technology by which software instrumentation data collected from user program sessions are analyzed to output an analysis report or the like via example methods and an architecture configured for efficient operation. A client component queries a service for analysis related information. To process the query, the service works with a data manager, and via a high dimensional analysis component may use information processed from the software instrumentation data, such as in the form of one or more inverted indexes and/or raw value files. The service may include a usage analysis component, a feature recognition component that locates features from command sequences, a user recognition component and/or a program reliability component. One or more counterpart components at the client may generate analysis reports or the like based on the query results. The client also may maintain user libraries and feature libraries to facilitate analyses.

摘要： In accordance with embodiments of the invention, global metadata, such as a document identifier, which may be a globally unique identifier, is embedded into an embedded interactive code document by combining a first m-array and a plurality of copies of the first m-array to generate a combined m-array with encoded global metadata such that respective start positions (xd,yd)i of the plurality of copies of the first m-array in the combined m-array are each shifted, by respective amounts that are based on respective portions of the global metadata, relative to a start position of the first m-array in the combined m-array. Global metadata may be decoded from the combined m-array by determining the respective amounts by which the plurality of copies of the first m-array are shifted, relative to the first m-array, in the combined m-array and by combining the respective amounts to produce a decoded value of the global metadata.
