摘要:
A method represents a shape of an object in an image. Portions of the image interior to a boundary of the object are ordered. A medial axis for the ordered portions of the image is derived. The medial axis is segmented to produce an ordered tree. The ordered tree is transformed to a partial ordered tree to represent the shape of the object.

A method detects a boundary in a sequence of two-dimensional images where each image has multiple intensity value points. Filtering and motion analysis is applied on each image to produce motion enhanced images. Initial search parameters are determined from a dynamic snake model applied to the motion enhanced images. Each motion enhanced image is searched for a potential boundary using the search parameters. The potential boundary is projected into the motion enhanced image of a previous, current, and next image, and the search parameters of the previous, current, and next images are updated. The searching, projecting, and updating repeat until a predetermined level of convergence is reached.

A method determines a surface of an object in a sequence of images. The method begins by estimating a boundary of the object in each image of the sequence using motion information of adjacent images of the sequence. Then, portions of each image of the sequence are ordered to produce an ordered sequence of images. The ordered portions are exterior to the estimated object boundary. Edges in each ordered image are filtered using the motion information, and each ordered image of the sequence is searched to locate the filtered edges to form a new boundary outside the estimated boundary. The filtering and searching are repeated, while projecting the new object boundaries over the sequence of images, until the new object boundaries converges to a surface of the object.
摘要:
A method for generating a representation of multimedia content by first segmenting the multimedia content spatially and temporally to extract objects. Feature extraction is applied to the objects to produce semantic and syntactic attributes, relations, and a containment set of content entities. The content entities are coded to produce directed acyclic graphs of the content entities, where each directed acyclic graph represents a particular interpretation of the multimedia content.

A system for print service provider (PSP) operations management includes a provenance analytics engine. The provenance analytics engine accesses fresh meta-data associated with fresh events in a PSP operation performed using a printing system operated by a PSP. The provenance analytics engine further accesses stored meta-data associated with past events related to past PSP operations. Still further, the provenance analytics engine accesses a component behavioral model (CBM) to produce results associated with events in a PSP operation. The provenance analytics engine analyzes the event-related meta-data.
摘要:
Systems and methods of data filtering for a print service provider (PSP) are disclosed. An exemplary method includes receiving a plurality of print service parameters. The method also includes filtering the plurality of print service parameters, wherein a portion of the received plurality of print service parameters are retained in machine readable format. The method also includes saving the filtered print service parameters for enhancing automatic and manual print production processes.
摘要:
In one aspect, images of a person's interactions with images presented on a display are captured. The person's interactions are segmented from the presented images in the captured images. A multimedia data object is generated. The multimedia data object includes a presentation media object containing digital representations of the presented images, an image presence media object containing the segmented interactions of the person, and at least one link synchronizing the presentation media object and the image presence media object.
摘要:
Systems and methods for determining a quantitative guideline are provided. One such method may involve receiving into an electronic device a print order from a customer to a print service provider, determining the requisite tasks to fulfill the print order, determining which resources of the print service provider are capable of undertaking the requisite tasks, and determining respective costs and lead times associated with undertaking each requisite task using each capable resource. In particular, such costs and lead times may be determined based at least in part on a dynamic behavioral model of cost and a dynamic behavioral model of lead time associated with each resource.
摘要:
A system, method, and apparatus are described in which a light point projected on a computer controlled displayed image is detected. A light point is projected at the displayed image at essentially the same time as a notification signal is transmitted indicating that the light point is being projected. At least one of image capture and image display parameters are adjusted to increase the detectability of the light point within a predetermined time interval after receipt of the notification signal. The image of the displayed image and the light point are captured within the predetermined time interval and the captured image data is analyzed to detect the light point dependent on the adjusted parameters.
摘要:
Systems and methods for color reproduction tolerances are provided. One method according to the present disclosure may involve selecting a printing configuration, printing a color scale sample using the printing configuration, and scoring the printed color scale sample based at least in part on an extent to which transpositions of the color swatches occur over a color range. When the score of the printed color scale sample indicates a print quality is or will be above a threshold level of quality, a print job using colors of the color range may be printed using the printing configuration.
