The invention relates to a method for bounding an object in a video sequence F. The method includes obtaining a subset of pixels located in the object to annotate, in each frame of the video sequence. Spatio-temporal slicing is performed on the video sequence F, centered on the obtained subsets of pixels, resulting in a first image Fobtained by an horizontal concatenation of first slices, comprising the obtained subsets of pixels, and resulting in a second image Fobtained by a vertical concatenation of second slices. A trajectory of the obtained subsets of pixels is displayed on both the first Fand second Fimage. A bounding form around the object to annotate is obtained out of four points in each frame of the video sequence, wherein the coordinates of the four points of a frame t are obtained from the coordinates of the points located in the first and second boundary of the first and second image for that frame t.

The present invention relates to a method for navigating over documents represented by identifiers displayed on a navigation menu. Each document is associated with a plurality of numerical values characterizing it according to a plurality of criteria. Each identifier of a document is placed at a position dependent on a part of the parameter values associated with this document. The whole set of the documents is subdivided into a given number of regions. The sums of the values associated with all the documents of a region and corresponding to a certain number of criteria are virtually equal for each region. The outer contour of the regions is displayed so as to enable its selection. The selection of a region triggers the display in full screen mode of all of the identifiers of the selected region. The invention also relates to a display device capable of executing the navigation method.

The invention relates to a method for determining identifiers associated with segments of a document. Each segment consists of a series of individual elements such as images or sound sequences. Each segment of the document is subdivided into a determined number of portions comprising the same number of individual elements. An individual element is extracted from the most central portion of each segment and associated with the segment as identifier. The invention also relates to the receiver capable of implementing the method.

The invention describes a creation method of a summary of an audiovisual document respecting both the criteria defined by the user and criteria helping in the understanding of said summary. The document is first split into sequences, each sequence associated with attribute values and a dependence parameter. The user first selects the first sequences either manually, or according to attribute values. Then second sequences are added according to the value of the dependence parameters. These added sequences enable a better understanding of the summary thus created. According to an improvement, the user introduces a maximum duration for the summary, first and/or second sequences are withdrawn from the summary if the duration of the summary thus created exceeds the introduced duration. The invention also relates to an audiovisual device for the creation and viewing of the summary.

Method of creating a summary of a document based on user-defined criteria, and related audio-visual device

The invention relates to a method for creating a new roundup of an audiovisual document previously recorded in a device. The document contains two parts, one being the roundup and the other composed of a plurality of reports. The roundup is itself divided into a plurality of parts. The device first searches for the associations between the roundup parts and the reports, and detects the reports that are not associated with roundup parts. Then, summaries are created for the reports not associated with the roundup, and incorporated into the initial roundup to create a new roundup. In this manner, the user can easily select any report from the roundup part associated with this report. The invention also relates to the receiver suitable for implementing the method.

The present invention relates to a method to create and reproduce a panoramic sound image. Initially, there is a plurality of images associated with sound sequences, these images are for example taken using a camera, this camera having recorded the ambient sound at the time of taking the photograph. The ambient sound is then filtered to keep only the stationary component. Then, the images are concatenated to form a unique image called 'panoramic', each sound sequence being associated with a part of the panoramic image containing the image associated with this sequence. Finally, the commands are introduced to display the parts of the panoramic image. The command also enables to reproduce continually the stationary component of at least a sound content associated with at least a displayed part of the panoramic image. According to an improvement, the sound sequence is reproduced continually until the introduction of a new command. The invention also relates to a reproduction device enabling the reproduction of a panoramic image and a sound sequence.

The present invention relates to a method for creation of an animated series of photographs. A photograph acquisition device analyzes the images in order to detect an absence of movement. The detection of an absence of movement during a determined period triggers a photograph to be taken and the memorization of image data in the series of photographs. The user introduces a command to end the acquisition of the series of photographs. The data of different photographs taken are assembled to form an animated series. During the reproduction, the series is reproduced by displaying successively each photograph, the time between each photograph reproduction can possibly be introduced by the user. The invention also relates to a photograph acquisition device designed acquire said animated series of photographs.

The present invention relates to a method for creation of a sound series of photographs. A sound series is produced by a camera and is audible to the user of the device. At various instants of the sound series, the user takes photographs and the device records the instant when the photograph was taken. A table is created associating each photograph with the instant of the sequence when it was taken. The sound sequence terminates then ending the series of photograph takes. Then, the photographs are assembled to form a single panoramic image, a part of the panoramic image is then displayed by an animation. The panoramic image thus created, the sound sequence and the table are assembled to form a panoramic sound image. During the reproduction of the panoramic sound image, each photograph is displayed at the instant associated by the table.

The present invention relates to a processing device of a sequence of video images intended to be displayed by a digital cinema projection system, a projection system for the digital cinema and a video signal designed to be used by such a system. The use of an anti-camcorder method against copying films is generally carried out entirely in the digital cinema projection system. However, this method requires complex video processing and costly means in the projection system. According to the invention, it is proposed to carry out part of the video processing at the level of the post-production of the video sequence and to save the result of this 'pre-processing' in the form of metadata. The remaining part of the video processing is carried out from this metadata in the video projection system.
