Abstract: An arrangement of a panoramic video is obtained by applying navigation commands to said panoramic video. The navigation commands are formed either by navigation commands given at will by the user, or by predefined navigation commands associated with said panoramic video. The choice of the type of navigation command used at a given instant is controlled either automatically or by the user. In this way, it is avoided that a user loses the thread of the action while permitting free navigation through a panoramic video.

Abstract: The invention relates to a system (200) for delineating an anatomical structure in an image computed from a slice of image data, the system (200) comprising a partition unit (210) for partitioning the image into a plurality of image portions, each image portion depicting a portion of the anatomical structure, and an adaptation unit (220) for adapting a template to the image based on a criterion function, the criterion function being a function of template parameters and of image values and their relative positions in the image, and on a criterion to be satisfied by a computed value of the criterion function, wherein the criterion function is defined on the basis of the plurality of image portions. Having a criterion function defined on the basis of the plurality of image portions allows computing optimal contributions to the criterion function value within each portion of the image.

Abstract: The invention relates to a medical imaging system. First, a sequence of images of a part of a body (BO) is acquired. Second, a feature of interest is detected automatically. Third, at least one parameter characteristic of said feature of interest for each image acquired is computed. Finally, the parameter having the 5 greatest value among the computed parameters is displayed automatically.

Abstract: A method for enhancing objects of interest represented on a moving background in a sequence of noisy images, and for displaying the sequence of enhanced images, the method comprising the steps of acquiring the sequence of images, extracting features related to an object of interest on a background in images from the sequence of acquired images or processed images, said features comprising at least two separately identified parts, registering separately each identified part with respect to an image from the sequence of acquired images, while not registering the background around said identified parts, to generate registered images of said identified parts, assembling together all registered identified parts from said object of interest using a weighted combination of said registered identified parts, to generate assembled images, integrating both said object of interest and said background over at least one assembled image and one acquired image, and displaying the processed images of the enhanced object of in

Abstract: An encoding and a decoding method for transmitting and storing description element(s) of an XML-like document which is an instance of an XML-like schema.

Abstract: The present invention relates to a descriptor for the representation, from a video indexing viewpoint, of motions of a camera or any kind of observer or observing device within any sequence of frames in a video scene. The motions are at least one or several of the following basic operations: fixed, panning (horizontal rotation), tracking (horizontal transverse movement) tilting (vertical rotation), booming (vertical transverse movement), zooming (changes of the focal length), dollying (translation along the optical axis) and rolling (rotation around the optical axis), or any combination of at least two of these operations. Each of said motion types, except fixed, is oriented and subdivided into two components that stand for two different directions, and represented by means of an histogram in which the values correspond to a predefined size of displacement. The invention also relates to an image retrieval system in which a video indexing device uses said descriptor.

Abstract: The invention relates to a method of searching a predetermined number of objects which are closest to an example, in a hierarchical object structure which is obtained by using a hierarchical object classification method. The proposed method consists of going through the hierarchical structure starting from the root, descending as far as the first node closest to the searched example of which a number of leaves lower than the number of lacking results depend, and then going back up to the brother node of this node which is closest to the searched example, so as to add other results and so on and so forth until said predetermined number is arrived at. Application: MPEG-7 descriptions.

Abstract: The invention notably has for its object to permit a user who uses multimedia content to make a search for an object of interest evoked in said content, without having to formulate the question himself. For this purpose, a selection tool (for example, a key) permits the user to select a passage of the content while he is using it. When the user makes a selection, a context data is extracted from the content (for example, the current reading time). This context data is then used for recovering one or more descriptions in a document (for example, an MPEG-7 document) which describes said content. The recovered descriptions are finally used for automatically formulating a question intended to be transmitted to a search engine.

Abstract: The invention relates to a partitioning method of a set of objects which comprises an initialization phase for determining a partition which has an optimal number of classes, and a modification phase of this partition for obtaining a partition whose classes have optimal contents from the point of view of the search for objects. The invention also relates to a multilevel partitioning method of partitioning a set of objects which utilizes such a partitioning method for creating a tree-like structure of objects. The invention finally relates to a search method, for example, of searching a certain number of objects which are closest to an example in the tree-like structure obtained in this manner.

Abstract: The invention proposes an interface device with a screen intended to be used with a device for restitution of multi-media content (for example a television) to perform searches on a multi-media content being restored.

Abstract: The invention proposes a device which makes it possible to generate a description of a structure of a multimedia content, for example of a video. In accordance with the invention an initial imperfect structure is generated using an automatic extraction algorithm known per se. The device includes means of displaying a visual representation of the structure obtained, and graphical manipulation means for modifying it. The description of the structure is updated in order to take account of these modifications.
