Abstract: An audio privacy system reduces the intelligibility of speech in an audio signal while preserving prosodic information, such as pitch, relative energy and intonation so that a listener has the ability to recognize environmental sounds but not the speech itself. An audio signal is processed to separate non-vocalic information, such as pitch and relative energy of speech, from vocalic regions, after which syllables are identified within the vocalic regions. Representations of the vocalic regions are computed to produce a vocal tract transfer function and an excitation. The vocal tract transfer function for each syllable is then replaced with the vocal tract transfer function from another prerecorded vocalic sound. In one aspect, the identity of the replacement vocalic sound is independent of the identity of the syllable being replaced.

Abstract: Systems and methods for interactive, user-driven detection, creation and completion of form fields in a digital document are provided. A document with form fields that require completion by a user is received, after which form fields are detected at the direction of the user. Once the user selects a possible form field, the system creates the appropriate fillable form field based on size, type, location, related text and other parameters of the form field and surrounding document. Additional levels of interaction include predictive text, pattern development and automatic completion of previously completed fields.

Abstract: Blogs (and other information sources) are recommended to a user based history of user's online activities. The system: (1) processes the user's web history, (2) identifies blog posts (and web pages) that link to pages read by the user, (3) generates multiple relevance scores for each identified post/page, and (4) produces multiple rankings of the corresponding source blogs (and web sites) by aggregating individual relevance scores (or combinations of relevance scores), according to users' preferences. The system allows the discovery of information sources that are likely to be interesting to the user and allows sources lost in the “long tail” to be seamlessly discovered.

Abstract: An element, such as a plug on a VGA cable, can communicate with a media storage unit to enable or disable media storage.

Abstract: A system helps filter and correct video captured and streamed from a mobile device. In particular, the system detects and streams content shown on screens, allowing anyone to stream screen content immediately without needing to develop hooks into external software (i.e. without installing a screen recorder software in the computer). The system can use a variety of user-selectable techniques to detect the screen, and utilizes the mobile device's touchscreen to allow users to manually override detected corners. However, some of these approaches could potentially be applied to other types of content, such as identifying TV screens, appliance LCD screens, other mobile devices' screens, multifunction devices. (e.g. a remote technician could help troubleshoot a malfunctioning MFD by having the end-user point his cellphone to the LCD screen of the MFD).

Abstract: A system and method for identifying key frames of a presentation video that include stationary informational content. A sequence of frames is obtained from a presentation video and differences of pixel values between consecutive frames of the sequence of frames are computed. Sets of consecutive frames that are stationary are identified, wherein consecutive frames that are stationary have a proportion of changed pixel values below a first predetermined threshold, and wherein pixel values are deemed to be changed when the difference between the pixel values for corresponding pixels in consecutive frames exceeds a second predetermined threshold. Next, a set of key frames that include stationary informational content is retained. The set of key frames that include stationary informational content is then displayed for user interaction.

Abstract: System and method that utilizes light sources, for example projectors embedded in mobile camera phones, to allow users to interact with documents on large displays without requiring users to install any third-party software. With this approach, multiple users can select interactors on the large display by displaying different images via their projector.

Abstract: A system and a method for sharing web pages. In some embodiments, the following operations are preformed at a client computer system having one or more processors that execute one or more programs stored in memory of the client computer system. A representation of a web page that is displayed in a window of a web browser in a user interface of the client computer system is generated. The representation of the web page is partitioned into a plurality of tiles based on a document object model of the web page. For each tile in the plurality of tiles, it is determined whether the tile has changed relative to a previous version of the tile. In response to determining that the tile has changed, the tile that has changed is sent to a server.

Abstract: A method and system for delivery of targeted advertisement via multifunction document imaging devices. Imaging devices used for copying, scanning, faxing and printing documents are used to deliver advertisements, coupons, and other promotional material to users. The imaging device is capable of delivering targeted promotional material based on analysis of the documents content passing through the device. Targeting is based on device history, user history or user demographics. Device history and user history are compiled from the contents of the documents processed respectively at a device and by a user. Demographics are inferred from a demographics model using user identity or document content input to the model. Advertisements may be delivered via paper, the device display, and other means.

Abstract: Described is a system and methods for embedding standard video-taking heuristics into video-recording devices to help improve the quality of captured video for consumer devices. The described approach uses a combination of audio, visual, and haptic feedback that responds to video as it is recorded. This feedback can help users compose better shots as well as help them develop an understanding of the fundamentals of good video-taking.

Abstract: Image search and retrieval system is provided. System identifies pictures embedded in presentation slides. System represents each set of identical (or nearly identical) images with unique token. For example, if specific picture is reused in multiple presentations, it will be represented by system using same token. System may compute and store various meta attributes associated with presentation slide and image(s) therein. After the token and meta attribute information are generated for images and/or slides, generated data is provided to text-based search engine. A searched image is subsequently located and retrieved by user using search query issued by user to text-based search engine, which locates images based on generated token and meta attribute information. At query time, user enters search keywords describing target image that user desires to locate. Pursuant to user's query, system retrieves all matching presentation slides. Found images may be ranked using, for example, tf*idf score.

Abstract: Systems and methods determine the location of a microphone with an unknown location, given the location of a number of other microphones by determining a difference in an arrival time between a first audio signal generated by and microphone with a known location and a second audio signal generated by another microphone with an unknown location, wherein the first and second audio signals are a representation of a substantially same sound emitted from an acoustic source with a known location; determining, based on at least the determined difference in arrival time, a distance between the acoustic source with the known location and the microphone with the unknown location; and determining, based on the determined distance between the acoustic source with the known location and the microphone with the unknown location, the location of the unknown microphone.

Abstract: The subject invention relates to a system and method for video summarization, and more specifically to a system for segmenting and classifying data from a video in order to create a summary video that preserves and summarizes relevant content. In one embodiment, the system first extracts appearance, motion, and audio features from a video in order to create video segments corresponding to the extracted features. The video segments are then classified as dynamic or static depending on the appearance-based and motion-based features extracted from each video segment. The classified video segments are then grouped into clusters to eliminate redundant content. Select video segments from each cluster are selected as summary segments, and the summary segments are compiled to form a summary video.

Abstract: A method of classifying images as slide images or non-slide images can be done by capturing a video stream, analyzing an image of the video stream and determining whether the image is a slide image. The analyzing can be based on text height and/or edge region(s) of the image.

Abstract: Provides a system for detecting an intersection between more than one panoramic video sequence and detecting the orientation of the sequences forming the intersection. Video images and corresponding location data are received. If required, the images and location data is processed to ensure the images contain location data. An intersection between two paths is then derived from the video images by deriving a rough intersection between two images, determining a neighborhood for the two images, and dividing each image in the neighborhood into strips. An identifying value is derived from each strip to create a row of strip values which are then converted to the frequency domain. A distance measure is taken between strips in the frequency domain, and the intersection is determined from the images having the smallest distance measure between them.
