Abstract: Systems and methods for editing electronic documents in collaborative environment are described. In one implementation, a document collaboration system comprises a processor, and a scheduling module, coupled to the processor. The scheduling module receives request of a user for either one of collaborative editing and collaborative reviewing a section of the electronic document during a schedule time selected by the user. The scheduling module further retrieves a schedule from the user from an electronic calendar of the user. The scheduling module ascertains the electronic document availability in the selected schedule time slot. On ascertaining the availability of the electronic document during the selected time slot, the scheduling module determines availability of users in the selected schedule time slot.

Abstract: Presented is a skew detection apparatus.

In another form, the apparatus includes a skew estimation unit adapted to estimate skew based on the orientation of foreground or background content in the interior of a document. In another form, the apparatus estimates skew using segments of an image of a document. Also presented is a document image processing apparatus including the skew detection apparatus.

Abstract: Provided is a method of integrating a document related communication with a document. A communication interface is provided for a user to establish a document related communication with another user.

Abstract: Disclosed are techniques pertaining to the creation of a social document through a collaboration. A server executing a social document management application may create a document comprised of content. The social document management application may also create an adhoc workflow process associated with the document in which the workflow process includes steps to create the content of the document. Collaborators may be assigned to work on the steps of the workflow process. In addition, tasks associated with the steps of the workflow process may be assigned to the collaborators and tracked. The tasks may be assigned by selecting content directly within the document and assigning a task pertaining to the selected content. The steps of the workflow process may then be approved.

Abstract: In one example, a method for image triggered transactions includes capturing an image of a document with an imaging device and searching a database for a template matching the captured image. If a matching template is found for the captured image, then retrieving pre-authored tasks associated with the captured image, extracting fields from the image related to the tasks, processing the extracted fields to obtain content to complete the tasks; and executing the selected task. If a matching template is not found for the captured image, then an authoring application is launched to add the captured image as a new template and author tasks associated with the captured image.

Abstract: A system and method for using paper to interface with handwritten annotations and/or pre-defined templates with one or more computer applications is disclosed. In one embodiment, the method includes imaging content in the paper including pre-defined handwritten commands, associated syntax, one or more computer application identifiers and pointed data which is already existing on the paper, analyzing the imaged content to identify the pre-defined handwritten commands, the one or more computer applications associated with the one or more computer application identifiers, the associated syntax and the pointed data, extracting the pointed data into a specified format associated with the one or more computer applications, executing the one or more computer applications based on the identified pre-defined handwritten commands, the one or more computer application identifiers and the associated syntax, and importing the extracted pointed data into the one or more executed computer applications.

Abstract: A physical document comprising a human-readable part and a machine-readable part, wherein the machine-readable part comprises markup that describes information on at least one of the document and data within the human-readable part.

Abstract: Provided is a method of integrating a document related communication with a document. A communication interface is provided for a user to establish a document related communication with another user. The document related communication with another user is recorded and a link to the recorded document related communication with another user is provided with the document.

Abstract: Disclosed is a printing system and method for printing documents over a network. The system comprises: a document server connected to the network, the documents being accessible via the document server; a client device connected to the network and adapted to transmit a document print request identifying a document to be printed; a print access server connected to the network and adapted to receive the document print request and, in response to the received document print request, transmit a print token, the print token identifying the document to be printed and a printer for printing the document; and a printer connected to the network, the printer being adapted to receive a print token and to retrieve and print a document via the document server based on the received print token.

Abstract: Presented is a method of automatically performing an action, based on graphical input. The method comprises: receiving, for a user, an input image; comparing the input image with the contents of a user-customized database comprising a plurality of records, each record representing a predefined class of image, wherein the user has previously associated records in the database with respective specified actions; attempting to recognize the image, based on the similarity of the input image to one of the predefined classes of image represented in the user-customized database; and if the image is recognized, performing the action previously associated by the user with the class. Also presented is apparatus for recognizing an image and a method of constructing a user-customized database.

Abstract: Presented is a method of posting content to a web site. A user input is obtained on a machine readable paper with a predefined template. Later, an electronic image of the machine readable paper is captured along with the user input. The electronic image of the machine readable paper is decoded to identify the predefined template and the predefined template is searched against a repository to find a web site corresponding to the predefined template of the machine readable paper. A web site based on user input is created or modified depending upon whether a web site corresponding to the predefined template of the machine readable paper is found.

Abstract: A media sheet is scanned. The media sheet has an image and an annotation. The annotation indicates a functionality to be performed in relation to the image. The annotation on the media sheet as scanned is detected. The functionality to be performed in relation to the image is determined in correspondence to the annotation detected on the media sheet. The functionality to which the annotation corresponds is performed in relation to the image.

Abstract: Presented is a method, for a participant in a secure document workflow, of generating workflow information for authenticating a document. The method comprises: receiving an image of the document; generating workflow information for the document image, including a document image descriptor dependent upon the appearance of the document image for later verifying the authenticity of a version of the document image that has been printed and scanned, the verification comprising electronically combining or comparing the document image descriptor with said version of the document image; generating a digital signature for later verifying the authenticity of the workflow information, the digital signature being derived from the workflow information using a cryptographic key associated with the participant; adding the digital signature to the workflow information; and communicating the document image and the workflow information to another workflow participant.
