  • Publication number: 20110194468
    Abstract: A method and architecture for pairing of Guard Band Frequencies in PGSM/EGSM 900 MHz and DCS 1800 MHz Bands, as also in US Cellular Bands and US PCS Bands, for effecting duplexed cellular mobile telecommunication services like I-Den, GSM, PGSM, EGSM, CDMA, CDMA 2000, UMTS & WCDMA & any other duplexed use in the guard bands. The method and architecture- of the present invention/innovation leads to two additional interspersed Bands available for exploitation of mobile cellular telecommunication systems, leading to an inherently additional utilization of spectrum that was unutilized in the Art, leading to a near optimal and efficient utilization of a scarce natural resource like spectrum. Further, this present embodiment leads to a balanced link compared to the embodiment in the Art.

  • Patent number: 6847733
    Abstract: An image is automatically assessed with respect to certain features, wherein the assessment is a determination of the degree of importance, interest or attractiveness of the image. First, a digital image is obtained corresponding to the image. Then one or more quantities are computed that are related to one or more features in the digital image, including one or more features pertaining to the content of the digital image. The quantities are processed with a reasoning algorithm that is trained on the opinions of one or more human observers, and an output is obtained from the reasoning algorithm that assesses the image. More specifically, the reasoning algorithm is a Bayesian network that provides a score which, when done for a group of images, selects one image as the emphasis image or the appeal image. The features pertaining to the content of the digital image include people-related features and/or subject-related features.

  • Patent number: 6826316
    Abstract: A system and method for determining image similarity. The method includes the steps of automatically providing perceptually significant features of main subject or background of a first image; automatically providing perceptually significant features of main subject or background of a second image; automatically comparing the perceptually significant features of the main subject or the background of the first image to the main subject or the background of the second image; and providing an output in response thereto. In the illustrative implementation, the features are provided by a number of belief levels, where the number of belief levels are preferably greater than two. The perceptually significant features include color, texture and/or shape. In the preferred embodiment, the main subject is indicated by a continuously valued belief map.

  • Patent number: 6804684
    Abstract: A method of generating captions or semantic labels for an acquired image is based upon similarity between the acquired image and one or more stored images that are maintained in an image database environment, where the stored images have preexisting captions or labels associated with them. The method includes the steps of: a) acquiring an image for evaluation with respect to the stored images; b) automatically extracting metadata from the acquired image without requiring user interaction in the image database environment; c) automatically selecting one or more stored images having metadata similar to the extracted metadata, thereby providing selected stored images with metadata similar to the acquired image; and d) generating captions or labels for the acquired image from the preexisting captions or labels associated with the selected stored images.

  • Publication number: 20040196250
    Abstract: A method for evaluating colorimetry of viewing conditions affecting a viewer and calibrating a display device used by the viewer relative to an environment surrounding the display device is based on measuring display colorimetry data and the colorimetry of the viewing conditions and generating display and viewing condition colorimetry data, wherein the viewing conditions include the effect of surround light originating from the environment surrounding the display device and impinging upon the viewer rather than the display device. A color conversion function is calculated from the display colorimetry data and the viewing condition colorimetry data, where the color conversion function is capable of transforming an input video signal into a transformed video signal that shows an improved image based on the colorimetry of the display device and the colorimetry of the viewing conditions.

  • Patent number: 6801661
    Abstract: A method for representing an image in terms of the shape properties of its identified segments of interest involves analyzing each segment of interest to automatically identify one or more of its perceptually significant components and then representing each perceptually significant component in terms of its shape properties, e.g., by means of Fourier descriptors. The image segment is then characterized as a composition of the shape properties of its perceptually significant components. By repeating the foregoing steps, the image is represented as a composition of its characterized segments. This technique can then be used to archive and retrieve images based on the shape properties of identified segments.

  • Patent number: 6711291
    Abstract: A method for placing a human understandable item, such as a caption, text or a figurative element, in a digital image includes the steps of (a) digitally processing the digital image to recognize and identify an optimal location in the digital image for placing the item and (b) modifying the placement of the item in relation to human understandable image content so as to minimally obscure such human understandable image content in the digital image. The recognition and identification of an optimal location further includes the identification of an optimal open space region and then finding an optimal location for the item within the open space region. The placement of the item may be done so as to minimally obscure human understandable image content either in other locations of the optimal open space region, or in regions of the digital image adjoining the optimal open space region.

  • Patent number: 6665423
    Abstract: An object-oriented method for describing the content of a video sequence comprises the steps of (a) establishing a temporal object-based segment for an object of interest; (b) describing the temporal object-based segment by describing one or more semantic motions of the object within its temporal object-based segment; and (c) describing the temporal object-based segment by describing one or more semantic interactions of the object with one or more other objects within its temporal object-based segment. The semantic motions of the object may be further described in terms of the properties of elementary coherent motions within the semantic motion. Additionally, the semantic interactions of the object may be further described in terms of the properties of the elementary spatio-temporal relationships among the interacting objects.

  • Patent number: 6584465
    Abstract: A method for retrieving digital patterns similar to a query pattern operates by generating representations of each digital pattern in terms of one or more color invariant properties; storing and organizing the patterns and their representations in a database; and searching the database by reference to the representations to identify and retrieve patterns similar to the query pattern. A preferred color invariant property is an edge property of the digital patterns. A web-based pattern registration and searching architecture enables on-line pattern search and selection utilizing a variety of pattern representations and similarity techniques, including the edge property based system described above.
