    摘要： 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. The parameters for any of the steps in the summarization of the video can be altered so that a user can adapt the system to any type of video, although the system is designed to summarize unstructured videos where the content is unknown. In another aspect, audio features can also be used to further summarize video with certain audio properties.

    摘要： 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. A modified audio signal is then synthesized with the original prosodic information and the modified vocal tract transfer function to produce unintelligible speech that preserves the pitch and energy of the speech as well as environmental sounds.

    摘要： 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.

    摘要： Systems and methods are directed to use-based product searching. Raw product information data, such as product features, specifications, and user reviews are processed and analyzed using pattern-based text analysis to extract relevant product aspects and uses. The aspects are weighted in relation to their importance for various uses, and the corresponding aspects and their weights are linked to the uses. A user selects uses for a product, which correspond to weighted aspects, and the weights for the aspects are used to rank products using the weights of the aspects linked to the selected uses. The ranked products are presented to the user in a customizable interface. The user may directly specify weights for the extracted aspects to further customize the ranked list of products. The interface provides additional options for viewing product details, opinions and comparisons.

    摘要： Visual tracking of multiple objects in a crowded scene is critical for many applications include surveillance, video conference and human computer interaction. Complex interactions between objects result in partial or significant occlusions, making tracking a highly challenging problem. Presented is a novel efficient approach to tracking a varying number of objects through occlusion. The object tracking during occlusion is posed as a track-based segmentation problem in the joint-object space. Appearance models are used to interpret the foreground into multiple layer probabilistic masks in a Bayesian framework. The search for optimal segmentation solution is achieved by a greedy searching algorithm and integral image for real-time computing. Promising results on several challenging video surveillance sequences have been demonstrated.
