US Classification:

382294, 382284

Abstract:

A system for automatically generating a mosaic from a plurality of input images. The system sequentially executes an image alignment process, an editing process, and a combining process such that, from a sequence of images, the system automatically produces a seamless mosaic for various applications. Illustrative applications for the mosaic include: (1) a mosaic based display system including an image printing system, (2) a surveillance system and (3) a mosaic based compression system. The mosaic based display system permits a system user to display, manipulate and alter a mosaic. The mosaic based compression system exploits the temporal and spatial redundancy in image sequences and efficiently compresses the image information. The compression system can be used for compressing image information for storage in a storage device or can be used for compressing image information for transmission through a band-limited transmission channel. The surveillance system combines the mosaic construction system, the compression system and the display system into a comprehensive system for remote motion detection.

International Classification:

US Classification:

382294, 382154, 382282, 382284

Abstract:

A method for fixating a camera, mounted on a motorized mount, on a target point. The method includes receiving a plurality of images representative of a scene; selecting, within the plurality of images, a first display reference image containing the target point at a first coordinate location; estimating, in a current image within the plurality of images, a transformation that maps the current image to the first display reference image; estimating a second coordinate location of the target point in the current image using the transformation; computing an image slip between the target point in the current image and the target point in the first display reference image; converting the image slip into an angular correction for fixating the camera; modifying the angular correction by using closed-loop control with the motorized mount; and warping the current image using the transformation to align the current image with the first display reference image. This warping step provides a stable view of the scene even in the presence of camera movements that cannot be eliminated using mechanical stabilization, and in the presence of motor control lags and oscillations due to measurement and actuator latencies.

International Classification:

G06K 900

US Classification:

382107, 382260

Abstract:

Apparatus and a concomitant method of identifying the direction of motion within a scene that is represented by a sequence of images, e. g. , a series of frames in a video sequence. The apparatus contains a flow field generator, a flow field segmentor, and alarm detector and an alarm processor. The flow field generator processes the sequence of images and generates a substantially distortionless flow field representing the motion within a scene. The flow field is a vector representation of the motion of the scene that represents both the magnitude and the direction of the motion. The flow field is generated by correlating at least two frames in the sequence of images. This flow field is analyzed by a flow field segmentor to determine the magnitude and direction of motion with the scene and segment the motion information from the static portions of the scene. An alarm detector then processes the motion information to determine if an alarm should be generated based upon the motion information. The alarm processor activates an appropriate alarm response, e. g.

US Classification:

382100, 382106, 382107, 382260, 348143

Abstract:

A method and system for improving the accuracy and timeliness of video metadata by incorporating information related to the motion of the camera as derived from the video imagery itself. Frame-to-frame correspondences are used to accurately estimate changes in camera pose. While the method and system do not require geo-registration, geo-registration results, if available, may be considered in processing the video images and generating improved camera pose estimates.

Abstract:

A media content capture and distribution system includes at least one capture system which provides clips of media content satisfying a set of at least one trigger defined for the capture system. The clips are transmitted to a distribution system. A channel creator in the distribution system combines a plurality of the clips that satisfy at least a portion of the criteria defining the content requirements of a microchannel into a microchannel stream. The microchannel stream is transmitted to a client through a computer network.

International Classification:

H04N007/18

US Classification:

348/140000

Abstract:

A method and apparatus for performing georegistration using both a telemetry based rendering technique and an interative rendering technique. The method begins with a telemetry based rendering that produces reference imagery that substantially matches a view being imaged by the camera. The reference imagery is rendered using the telemetry of the present camera orientation. Upon obtaining a certain level of accuracy, the method proceeds to perform iterative rendering. During iterative rendering, the method uses image motion information from the video to enhance rendering of the reference imagery. A further embodiment uses sequential statistical framework to provide a unified approach to georegistration.

US Classification:

382131

Abstract:

A reconstructed image is rendered from a set of MRI data by first estimating an image with an area which does not contain artifacts or has an artifact with a relative small magnitude. Corresponding data elements in the estimated image and a trial image are processed, for instance by multiplication, to generate an intermediate data set. The intermediate data set is transformed and minimized iteratively to generate a reconstructed image that is free or substantially free of artifacts. In one embodiment a Karhunen-Loeve Transform (KLT) is used. A sparsifying transformation may be applied to generate the reconstructed image. The sparsifying transformation may be also not be applied.
