A system and method for dynamically displaying structurally dissimilar thumbnail images generated from multiple pages of an electronic document based on a display size of a display device is disclosed. In one embodiment, one or more candidate images are selected based on a generated metric for dissimilarity for each one of multiple images associated with multiple pages of an electronic document, where the metric for dissimilarity for each one of the multiple images is generated by comparing each image of the multiple images with substantially previous images of the multiple images. Then, the selected one or more candidate images are dynamically displayed as structurally dissimilar thumbnail images based on a display size of a display device.

Provided is a method of detecting lip activity. The method determines magnitude of optical flow in lip region and at least one non-lip region of a detected face. The ratio of magnitude of optical flow in lip region and at least one non-lip region is compared against a threshold. If the ratio is found to be greater than the threshold, lip activity of the detected face is recognized.

Provided is a method of tagging media. The method identifies at least one region of interest in a media based on a user input and assigns a higher weighted tag to an object identified in at least one region of interest compared to an object present in another region of the media.

Systems and methods for estimating the distance between a start point and a true endpoint in which at least two functions of differing resolutions are used. The method includes measuring a coarse distance between the start point and an intermediate point using the lower resolution function, the intermediate point comprising a point which is substantially within one unit of the higher resolution function away from the true endpoint. Next, a vernier distance is measured from the intermediate point to a vernier endpoint using the higher resolution function, the vernier endpoint being within a narrow, vernier error window of the true endpoint. Subsequently, the coarse and vernier distances are summed to obtain the estimated distance.

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.

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.

A method of distributing content to an application from a server is disclosed. The method includes detecting in a file to be sent to the application from the server that the application is directed to request one or more resources to be downloaded to the application. A network latency associated with the downloading of the one or more resources is determined. A subset of the one or more resources is selectively packaged based at least in part on the network latency. The selectively packaged subset of the one or more resources is sent to the application.

Method, article, apparatus and computer system facilitating the easy and intuitive inputting of a desired graphical object into an electronic system from a large plurality of predetermined graphical objects. In one example embodiment, this is achieved by assigning each of said graphical objects into one of a plurality of groups in accordance with a predetermined similarity criterion, associating respective base shapes to each of said groups, wherein said base shapes having a certain degree of similarity to the objects assigned to the associated group according to said similarity criterion and associating in each of said groups at least one gesture to each of said graphical objects, so that the associated gestures are distinguishable from each other. In order to input the desired graphical object, one of the groups is selected by selecting its base shape and then the desired graphical object is identified by drawing the respective gesture associated thereto.
