Abstract: Systems and methods according to the present invention describe image processing techniques for processing images wherein a displayed image is potentially occluded. The occluding object can then itself be displayed on the video device. Passive and active testing techniques resolve ambiguity between the occluding object and the displayed image.

Abstract: A reference template is used to help in the reconstruction of a damaged workpiece, such as a turbine blade. The reference template is a copy of the workpiece from before it was used. The reference template is scanned in layers, including the portion corresponding to that which has been damaged in the workpiece, as well as adjacent undamaged portions. The adjacent undamaged portions of the workpiece are also scanned as layers. Profiles of the layers of the reference template and workpiece are generated, based on the scans. Sets of offsets are then determined based on corresponding points within adjacent scanned layers in the undamaged portion of the workpiece and the corresponding portion of the reference template and also within the portion of the reference template corresponding to the damaged portion of the workpiece.

Abstract: A system for recording a real-time slide presentation to generate a low bit-rate multimedia data object including a plurality of synchronized overlayed replayable bitstreams including at least a bitstream corresponding to an image of each of a plurality of slides of the slide presentation, a bitstream corresponding to symbolic representations of presenter's interactions with points of interest within each slide, and a bitstream corresponding to a presenter's audio associated with each slide is described. The plurality of bitstreams can be linked so as to make the multimedia data object browsable on a presenter interaction event-by-event basis. Interaction events can be linked to the audio bitstream and/or to a video clip bitstream. Video clips can be recorded during the real-time presentation such that when replaying the multimedia data object, a video clip is synchronized and replayed dependent on presenter interaction events.

Abstract: A system for generating a data object of a recording of a real-time slide presentation is described. The data object includes a plurality of synchronized overlaid replayable bitstreams including at least a bitstream corresponding to an image of each of a plurality of slides of the slide presentation, a bitstream corresponding to symbolic representations of presenter's interactions with points of interest within each slide, and a bitstream corresponding to a presenter's audio associated with each slide. The system generates the bitstream corresponding to the symbolic representation of the presenter's interactions from captured image data of the real-time presentation by identifying points of interest of located objects in front of the display area and assigning symbols to each point of interest. The symbolic representation bitstream is then synchronized with a corresponding audio bitstream and the slide image data of the presentation.

Abstract: A system, method, and apparatus are described in which a light point projected on a computer controlled displayed image is detected. A light point is projected at the displayed image at essentially the same time as a notification signal is transmitted indicating that the light point is being projected. At least one of image capture and image display parameters are adjusted to increase the detectability of the light point within a predetermined time interval after receipt of the notification signal. The image of the displayed image and the light point are captured within the predetermined time interval and the captured image data is analyzed to detect the light point dependent on the adjusted parameters.

Abstract: A technique of implementing a distributed real-time slide presentation environment for facilitating low bit rate bi-directional classroom participation is described. Initially, a real-time slide presentation is presented using a computer controlled display and is captured. The captured data is used to generate synchronized overlayed replayable bitstreams including at least a bitstream corresponding to symbolic representations of a presenter's interaction with each slide captured during the presentation. The bitstream is transmitted to at least one viewing location having the capability to play the bitstream during the real-time presentation. A low bit rate digital signal having a corresponding displayable visual representation can be transmitted from the viewing location to the presentation location.

Abstract: A method for generating a representation of multimedia content by first segmenting the multimedia content spatially and temporally to extract objects. Feature extraction is applied to the objects to produce semantic and syntactic attributes, relations, and a containment set of content entities. The content entities are coded to produce directed acyclic graphs of the content entities, where each directed acyclic graph represents a particular interpretation of the multimedia content.

Abstract: A system and method of identifying a point of interest of an object located in front of a computer controlled display area captured by an image capture device is performed by capturing an image of the display area within the capture area of the image capture device. Pixels within the captured data are identified that correspond to the object within the display area and to the peripheral boundary of the display area within the capture area. Pixels are identified and stored that correspond to the common subset of the object pixels and the peripheral boundary pixels. A search is performed using the common pixels and the object pixels to determine a pixel corresponding to the point of interest of the object in the display area within the capture area.

Abstract: A fixing device for a pen clip which contains a fixing cap, an upper casing, a fixing clip, an adjusting assembly and a lower casing. The upper casing is a hollow tube and has a trumpet-shaped mouthpiece (top wide while bottom narrow) for receiving the fixing cap in place. The fixing cap has an indentation to receive the fixing clip. A screw is tightened from the inner side of the adjusting assembly to the fixing cap. The trumpet-shaped mouthpiece of the upper casing will be expanded by the screw for a tight connection with the fixing clip so that the fixing clip is situated between the casing and the fixing cap and won't be easily disconnected. Accordingly, an additional fixing effect and a convenient application is achieved.

Abstract: A method for servowriting a magnetic hard disk drive includes servowriting a first servo burst pattern by using a servowriter coupled to a head-disk assembly within a clean room environment, self-writing at least a second servo burst pattern radially offset relative to the first burst pattern by reading the first burst pattern without using the servowriter, and self-writing a final burst pattern by using the first burst pattern and the second burst pattern without using the servowriter. One or more intermediate burst patterns may be provided to accommodate writer/reader offset of dual element read heads in order to produce final product servo burst patterns. A disk drive having embedded servo sectors each including an untrimmed six-burst final servo pattern is also disclosed. The disk drive self-writes at least some of the final servo pattern.

Abstract: A method determines a surface of an object in a sequence of images. The method begins by estimating a boundary of the object in each image of the sequence using motion information of adjacent images of the sequence. Then, portions of each image of the sequence are ordered to produce an ordered sequence of images. The ordered portions are exterior to the estimated object boundary. Edges in each ordered image are filtered using the motion information, and each ordered image of the sequence is searched to locate the filtered edges to form a new boundary outside the estimated boundary. The filtering and searching are repeated, while projecting the new object boundaries over the sequence of images, until the new object boundaries converges to a surface of the object.

Abstract: A method represents a shape of an object in an image. Portions of the image interior to a boundary of the object are ordered. A medial axis for the ordered portions of the image is derived. The medial axis is segmented to produce an ordered tree. The ordered tree is transformed to a partial ordered tree to represent the shape of the object.
