An example method includes dividing the image into blocks of pixels of a predefined size; for each block, selecting one of a plurality of saturation patterns representing a binary value of one or more bits of digital watermark data corresponding to the block; and for each block, embedding the binary value of the one or more bits of corresponding digital watermark data into the block by adjusting the saturation of pixels within the block in accordance with the selected pattern.

Digital watermarking using saturation patterns

Disclosed is a method of blending stitched document image portions. The method identifies background pixels and foreground pixels on each boundary of the image portions. Pixels of the image portions are then modified based on a pixel value difference between corresponding background pixels on the respective boundary of the first and second portions.

Semantically ranking content in a website () with a computerized ranking device () includes: parsing content from the website () into multiple autonomous content blocks (-to-) with the computerized ranking device () and assigning an importance ranking with said computerized ranking device () to each of the content blocks (-to-) based on a degree to which a substance of the content block (-to-) is relevant to one of a plurality of predefined categories.

Semantically ranking content in a website

A system and method of detecting separator lines in a web page may include determining coordinates of visible web elements on a web page, generating an edge image of the web page based on the coordinates of the web elements, filtering edges belonging to non-separator line elements within the edge image, detecting horizontal lines within the edge image, detecting vertical lines within the edge image, and filtering short lines within the edge image. A system for detecting separator lines in a web page may include a memory device, and a processor communicatively coupled to the memory, in which the processor determines coordinates of visible web elements on a web page, generates an edge image of the web page based on the coordinates of the web elements, filters edges belonging to non-separator line elements within the edge image, detects horizontal lines within the edge image, detects vertical lines within the edge image, and filters short lines within the edge image.

Detecting separator lines in a web page

Proposed is the use of an email-stamp for representing an email address. By comprising information about one or more email addresses of a recipient, an email stamp may be processed in accordance with an optical recognition process so as to identify the email address of the recipient and enable an email to be automatically sent to the recipient.

Communicating electronic mail

A method of grouping a plurality of media content is provided. The method includes converting at least a portion of the media content into at least one document object model ('DOM') using a processor. The DOM can include a plurality of block elements, each comprising at least one content object. The method includes apportioning the content objects into a relevant portion and an irrelevant portion and extracting a set of keywords, the set comprising at least one keyword, within the relevant portion of the content objects. The method includes apportioning the relevant portion of the content objects into a related portion and an unrelated portion using at least a portion of the set of keywords and grouping the related portion of the content to provide a group of related content.

Content grouping systems and methods

An exemplary embodiment of the present may generate a DOM-tree and generate a signal based on the DOM-tree and a node list. The signal may be analyzed and nodes may be selected within the signal to form a periodic wave. Repeat patterns may be detected using the periodic wave and the nodes.
