A method and apparatus for handling restricted access and server/client handoffs in a communication environment is described. In one embodiment, the method includes receiving a first request for a first set of image data corresponding to an image, and responding to the first request with the first set of image data. The method may also include receiving a second request for a second set of image data corresponding to the image and determining that the second set of image data includes restricted data. A prompt for authentication may then be sent. The method may also include receiving the second request along with authentication information, determining again that the second request is for restricted data, and checking the authentication information. If the authentication information is correct, the method may also include providing the second set of image data.

A method and apparatus for transporting portions of a codestream over a communications mechanism is described. In one embodiment, the method comprises sending a request over a network and receiving tile-parts of a JPEG 2000 compliant codestream from the network as a return type as part of a response to the request.

A method and apparatus for performing partial image uploads. In one embodiment, the method comprises the server sending a portion of the compressed data of a codestream corresponding to an entire image to a client in response to a first request, the server receiving a second request from the client, the server determining the second request is an upload request, and the server combining compressed data of the third request with the codestream for the entire image.

Provided is a method for performing analysis on an image. An image is provided to users, wherein contents of the image are hidden from the users. Information regarding the contents of the image is collected from the users wherein a question is posed to the users to determine contents of the image. Alternate inputs are received from the users to reveal the contents of the image, wherein each input from the users partially reveals the contents of the image. A response to the question from the users is received until it is determined that an input from one of the users would reveal an identity of a human subject present in the image.

Presented is a skew detection apparatus. In one form, the apparatus estimates skew based on the locations of a set of foreground content pixels or a set of edge pixels that are nearest to the side of an image of a document. 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.

Proposed is the use of a document widget for representing a property of a document. The document widget comprises: a human-readable portion for interpretation by a user; and a machine-readable portion representing the document property. By comprising information about a property of a document, a document widget may be processed in accordance with an optical recognition process so as to identify the document widget and enable extraction of the document property.

A system and method for classification of moving objects and user authoring of new object classes is disclosed. In one embodiment, in a method of classification of moving objects, a moving object is inputted. Then, an object descriptor and a motion descriptor are extracted from the inputted moving object. Multiple initial candidate library object descriptors are identified from an object library and a motion library using the extracted object descriptor and the extracted motion descriptor. An initial object class estimate is identified based on the identified multiple initial candidate library object descriptors. Then, an initial residue is computed based on the extracted object descriptor and the identified multiple initial candidate library object descriptors associated with the initial object class estimate. The object class estimates are iteratively identified and it is determined whether the object class estimates converge based on a stopping criterion.

An edge detection method and apparatus is disclosed. The method comprises the steps of: calculating a pixel gradient value for each of a plurality of pixels of a digital image, the pixel gradient value representing the difference of a pixel value with respect to at least one neighboring pixel; for each of a plurality of binarization threshold values, determining a corresponding edge map representing the location of pixel gradient values exceeding the binarization threshold value with respect to a side of the digital image; for each edge map, computing a measure of linearity; determining an optimal binarization threshold value based on the computed measures of linearity; and selecting the edge map corresponding to the optimal binarization threshold value.

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.
