Abstract:

System and method for partitioning a video into a series of semantic units where each semantic unit relates to a generally complete thematic topic. A computer implemented method for partitioning a video into a series of semantic units wherein each semantic unit relates to a theme or a topic, comprises dividing a video into a plurality of homogeneous segments, analyzing audio and visual content of the video, extracting a plurality of keywords from the speech content of each of the plurality of homogeneous segments of the video, and detecting and merging a plurality of groups of semantically related and temporally adjacent homogeneous segments into a series of semantic units in accordance with the results of both the audio and visual analysis and the keyword extraction. The present invention can be applied to generate important table-of-contents as well as index tables for videos to facilitate efficient video topic searching and browsing.

International Classification:

US Classification:

704256, 704245, 704270

Abstract:

Disclosed is a general framework for extracting semantics from composite media content at various resolutions. Specifically, given a media stream, which may consist of various types of media modalities including audio, visual, text and graphics information, the disclosed framework describes how various types of semantics could be extracted at different levels by exploiting and integrating different media features. The output of this framework is a series of tagged (or annotated) media segments at different scales. Specifically, at the lowest resolution, the media segments are characterized in a more general and broader sense, thus they are identified at a larger scale; while at the highest resolution, the media content is more specifically analyzed, inspected and identified, which thus results in small-scaled media segments.

US Classification:

382104, 340933

Abstract:

A method, information processing system, and computer program storage product annotate video images associated with an environmental situation based on detected actions of a human interacting with the environmental situation. A set of real-time video images are received that are captured by at least one video camera associated with an environment presenting one or more environmental situations to a human. One or more user actions made by the human that is associated with the set of real-time video images with respect to the environmental situation are monitored. A determination is made, based on the monitoring, that the human driver has one of performed and failed to perform at least one action associated with one or more images of the set of real-time video images. The one or more images of the set of real-time video images are annotated with a set of annotations.

International Classification:

H01L 21/00

US Classification:

438586, 438197, 438216

Abstract:

A conductive top surface of a replacement gate stack is recessed relative to a top surface of a planarization dielectric layer by at least one etch. A dielectric capping layer is deposited over the planarization dielectric layer and the top surface of the replacement gate stack so that the top surface of a portion of the dielectric capping layer over the replacement gate stack is vertically recessed relative to another portion of the dielectric layer above the planarization dielectric layer. The vertical offset of the dielectric capping layer can be employed in conjunction with selective via etch processes to form a self-aligned contact structure.

Each gate stack includes, from bottom to top, a high k gate dielectric layer, a work function metal layer and a conductive metal. A spacer is located on sidewalls of each gate stack and a self-aligned dielectric liner is present on an upper surface of each spacer. A bottom surface of each self-aligned dielectric liner is present on an upper surface of a semiconductor metal alloy. A contact metal is located between neighboring gate stacks and is separated from each gate stack by the self-aligned dielectric liner. The structure also includes another contact metal having a portion that is located on and in direct contact with an upper surface of the contact metal and another portion that is located on and in direct contact with the conductive metal of one of the gate stacks. Methods of forming the semiconductor structure using a replacement gate and a non-replacement gate scheme are also disclosed.
