Method for modifying a style of an audio object, and corresponding electronic device, computer readable program products and computer readable storage medium The disclosure relates to a method for processing an input audio signal. According to an embodiment, the method includes obtaining a base audio signal being a copy of the input audio signal and generating an output audio signal from the base signal, the output audio signal having style features obtained by modifying the base signal so that a distance between base style features representative of a style of the base signal and a reference style feature decreases. The disclosure also relates to corresponding electronic device, computer readable program product and computer readable storage medium.

A method provides translation of metadata related to enhancement of a video signal according to a first high dynamic range video distribution type into metadata related to enhancement of a video signal according to a second high dynamic range video distribution type. Translation is done between a value of a first metadata set corresponding to a first type of high dynamic range video and a value of a second metadata set corresponding to a second type of high dynamic range video and uses an association that may be stored in a lookup table that is determined according to differences between a test image reconstructed using the metadata of first type and the same image reconstructed using the metadata of second type. A receiver apparatus and a transmitter apparatus comprising the translation method are also disclosed.

A method for tracking an object commences by first establishing the object () in a current frame. Thereafter, a background region () is established encompassing the object in the current frame. The location for the object () is then estimated in a next frame. Next, the propagation of the background region () is determined. Finally, the object is segmented from its background based on propagation of the background region, thereby allowing tracking of the object from frame to frame.

A method and an apparatus for determining an orientation of a video are suggested. The method comprises the steps of: estimating a motion of the video; extracting translation-based parameters from the estimated motion of the video; and computing at least one feature giving the evolution of the horizontal translation over time against the evolution of the vertical translation according to the translation based parameters, the feature being used for determining the orientation of the video.

A method and a system of audio retrieval and source separation are described. The method comprises the steps of: receiving a textual query; retrieving a preliminary audio sample from an auxiliary audio database; retrieving a target audio sample from a target audio database; and separating the retrieved target audio sample into a plurality of audio source signals. The corresponding system comprises an input unit, a storing unit and a processing unit to implement the method.

A device and a method for online storage, device and method for searching for similar content, a device and a method of transmission and a device and a method. Encrypted data is saved at a provider of online services. With the encrypted data, encrypted hashing data is saved with a public key and the content to save is encrypted with the encrypted hash. This advantageously enables data duplication at the online service provider to be prevented while preserving the private life of the users of the service. In order to search for content similar to reference multimedia data, fingerprints are also saved at the service provider. In order to limit the number of false positives returned, the fingerprint can further contain a search fingerprint, an encrypted selection fingerprint.
