A method and an apparatus for displaying light field video data are described. A receiving unit of the apparatus receives light field video data including a plurality of light field video sequences. Each light field video frames of of the light field video sequences has multiple selectable viewpoints. A light field video frame is provided by an operation unit and displayed on a display device with a first viewpoint. An input unit receives an input indicating a viewpoint different from the first viewpoint. The displayed light field video frame is then displayed with the indicated viewpoint. In one embodiment, two light field video frames of two light field video sequences are displayed respectively in main and side windows on the display device.

The disclosure relates to a method for classifying an object of a current image, a plurality of first landmarks representative of the shape of the object being associated with the current image, a first unique identifier being associated with each first landmark. According to the disclosure, the method includes, for at least a first landmark, a step of obtaining at least a first descriptor describing an area of the current image having the at least first selected landmark. Then, the first landmark is selected according to its first identifier, and when its first identifier corresponds to a second identifier of a second landmark, a second descriptor is used in a classifier for classifying the object. Finally, the method determines information representative of confidence of the shape according to the first descriptor and according to weighting information associated with the second descriptor.

A method for processing an image of pixels is described. The method includes determining a plurality of features representative of the image, obtaining both information representative of a probability of presence of an object in the image and information representative of a shape of the object by implementing a unique multivariate regression applied to at least a part of the features.

The disclosure relates to a method for determining the shape (S) of an object represented in a current image, a plurality of landmarks being associated with the object. According to the disclosure, the method includes determining a plurality of features (F) representative of the current image, and the features being determined from at least a part of the plurality of landmarks. The method further obtains information (S) representative of the shape of the object by using at least one parameter (P) representative of an estimation of the pose of the object in the current image, the at least one parameter being obtained by implementing a multivariate regression applied to at least a part of the set of features.

A method and an electronic device for object tracking in a sequence of light-field captures. A data acquisition unit acquires a sequence of light-field captures, wherein each light-field capture comprises a plurality of views. A feature determining unit determines features of an initial visual appearance model for an object of interest in a reference view of a first light-field capture. A feature matching unit matches the features in the reference view and in the further views of the first light-field capture. A feature discarding unit discards features that cannot be well matched in all views of the first light-field capture. An appearance model building unit builds an updated visual appearance model for the object of interest based on the remaining features. Finally, a movement tracking unit tracks the movement of the object of interest in the sequence of light-field captures using the visual appearance model.

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 for selection of a first object in a first virtual environment, the first object being represented in the first environment with a size of value less than a threshold value. According to an exemplary embodiment, in order to make the selection of the first object more convivial, the method includes steps for: estimating a direction associated with a pointing gesture of a user, determining a second object according to the estimated direction, the second object having a size of value greater than the threshold value, and selecting of the first object according to the second determined object. The invention also relates to a multimedia terminal adapted for the implementation of the method for selection.

A Braille display system and a method for operating a refreshable Braille displayis provided. A string of characters is assigned to a drive signal for specifying the activation or deactivation of a tuple of dots which are raised through holes in a touch and sense surface of the Braille displayupon activation and which are retracted upon deactivation. The Braille displayis driven by a drive signal which is configured to activate and/or to deactivate the tuple of dots so as to generate a dynamic tactile display of said string of characters. The time dependent characteristic of activation and/or deactivation of the tuple of dots is defined by the string of characters.

A visual summary of the image sequences is generated, displaying at least one image from a plurality of the image sequences. Color correction is applied to a feature in one of the displayed images and images comprising at least one feature being close to the color corrected feature according to a distance criterion are selected, displayed, and color correction, based on the color correction to the feature, is applied to the features in the selected images. An apparatus is also provided.

The invention concerns a device and an automatic resetting method using electronic means intended for a geometric model of a scene over a picture of the scene including fixed references, the electronic means comparing the picture with model having been adjusted in perspective by homography for superimposition of the references. According to the invention, the electronic device calculates a fine homography function Hfor resetting into three phases: a first preliminary phase of determination of an average resetting homography consisting in determining an average homography function Happlicable to the model with average adjustment over a sample of pictures of the scene taken previously, a second, rough resetting phase consisting after application of the average homography function H, to the model in determining a rough homography function H, and a third, fine resetting phase consisting after application of the rough homography function Hg to the model in determining the fine homography function H.
