摘要:
A system and method are provided for determining a color palette model from an image of a document. Pixel values of the image of the document are clustered to provide image clusters. Color layers of the image are determined, each color layer corresponding to an image cluster. Aspects of the color palette model can be determined using the color layers. Aspects of the color palette model include a foreground-background color pair for a content block in the document and a background-area color of the document.

In a method of evaluating compositional quality of a layout orientation of an image, image saliency data is received for an image to be presented in a viewing region. A layout orientation for presenting the image in the viewing region is received. A composition template embodying an image composition rule is received. The image saliency data and the composition template are utilized to determine a weighted occlusion cost for the layout orientation. The weighted occlusion cost is utilized to determine a composition score indicating quality of the layout orientation with respect to the image composition rule.

Methods, systems and machine-readable instructions for managing images are described. In one aspect, images are segmented into image clusters. A page layout for a contact sheet comprising thumbnail clusters each comprising thumbnails of the images in respective ones of the image clusters is generated. The page layout divides at least a portion of the contact sheet into regions each containing a respective one of the thumbnail clusters and at least one associated user input field. A description of the page layout is stored on a machine-readable medium.

In a method for generating a dimensionally tractable set of image layout constraints, a selected constraint is applied to limit a dimension of a highly dimensional solution space. Through random selection one or more unconstrained dimensions of the highly dimensional solution space are identified which, when constrained, will further limit the highly dimensional solution space to a dimensionally tractable solution space. The tractability of the dimensionally tractable solution space is associated with a capability of a computational resource.

Methods, devices, and systems for profile driven extraction are provided. An example of profile driven extraction includes utilizing an extraction profile created for extracting a subset of content from a particular type of web page, extracting the subset of the content from a number of web pages with a computing device, and transforming the subset of the content with the computing device into a displayable format.

Methods and Systems for automatically providing a graphical layout based on an example graphic layout are disclosed. In general, a block boundary analysis is used to identify spatial characteristics of the example graphic layout and an actual content. A database is searched for one or more graphical templates having spatial characteristics that are similar to the spatial characteristics of the example graphic layout. A fit analysis with the spatial characteristics of the actual content is also performed on the graphical templates. The resulting graphical templates are ranked. At least one of the graphical templates in the ranking is automatically filled with the actual content and provided in place of the example graphic layout.

A system for creating an album is disclosed. In one embodiment, the system includes an image input configured to receive related images, an image memory coupled to image input, an image processor coupled to image memory, and an album output coupled to image processor. The image processor is configured to use game play with users to assign metadata labels to the related images and assign album layout rules based upon the story schema and metadata labels.

The invention provides for encryption of hierarchically structured information. In one embodiment, a method is provided for encrypting hierarchically structured information. The hierarchically structured information includes a particular node and zero or more descendent nodes, each node having a name and zero or more additional data for the node. The name of the particular node is encrypted and the encrypted name is stored. The one or more descendent nodes are stored with the parent-child relationships of the one or more descendent nodes exposed. Additional data for the particular node may be encrypted. Further, some, none or all of the data for the descendent nodes may be encrypted.

A single sign-on technique suitable for a network of devices with no centralized device or synchronized clocks such as a personal area network (PAN) is described. Responsive to a user signing-on to a first device via its user interface, the first device securely propagates authentication of the user for enabling one or more other devices in the network, each for a near-expiry time period measured from the device specific time of the respective device; thus providing for expiration of authentication to minimize how long data is vulnerable in case a device is lost or stolen. Described also is a device enabling protocol using authentication accumulation to secure against threats from a rogue device pretending to be another device in the network such as in man-in-the-middle and replay attacks.

In a method of evaluating an image for a dominant line, warped mesh information regarding saliency of the image is received. Displacements of components of the warped mesh information are determined relative to corresponding components in un-warped mesh information. Statistical representations of the displacements are utilized to evaluate the image for a dominant line.
