Automatic tracking by a camera of an object such as on-air talent appearing in a television show commences by first determining whether the object lies within the camera field of view matches a reference object. If so, tracking of the object then occurs to maintain the object in fixed relationship to a pre-set location in the camera's field of view, provided the designated object has moved more than a threshold distance from the pre-set location.

A method for controlling tracking using a color model is disclosed. The method includes obtaining a window in a second frame of a video image corresponding to a window in a first frame of the video image using a tracking algorithm in a tracking mode, wherein each pixel in the video image has at least one color component. The method further includes defining a background area around the window in the first frame, assigning a pixel confidence value for each pixel in the second frame according to a color model, assigning a window confidence value for the window in the second frame according to the pixel confidence values of pixels in the window in the second frame, if the window confidence value is greater than a first confidence threshold, selecting the tracking mode, and if the window confidence value is not greater than the first confidence threshold, selecting a mode different from the tracking mode.

Objects in an image sequence are tracked within a bounding box such that the object is assured to some extent of being contained within the bounding box. The location of the object within the bounding box is less important than knowing with some certainty that the object is within the bounding box, unlike previous methods that attempt to center an object within a bounding box. The approach, which uses histograms of image features such as color indices, is suited to applications such as zooming and is robust to occlusions, out-of-plane rotations, illumination changes and long-term tracking drift.

The application concerns a method for transmitting video data in a data stream and associated metadata, said metadata representing associated video data structure. The method comprises the steps of&#x2014;determining the structure of the video data, &#x2014;splitting said structure into chunks in an incremental manner, &#x2014;transmitting said chunks in the data stream at time intervals before the video data it is related to. The application concerns also a method for transmitting fingerprint information associated with video data into a video data stream. The method comprises the steps of: &#x2014;determining fingerprint associated with at least one frame of said video data, &#x2014;inserting at least a message into the video stream comprising said fingerprint information.

The invention relates to a method of selecting parts of an audiovisual document. First, the document is analyzed by at least two subdividing means in order to extract from it at least two groups of audiovisual sequences. Then, selection criteria associated with each of the two subdividing means are entered. Finally, a list of sequences responding to all the selection criteria entered previously is generated. According to a refinement, the sequences are concatenated in a chronological order in order to generate an audiovisual document representative of the audiovisual document. The invention also relates to a device for displaying the sequences selected according to 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.

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.
