Abstract: The invention concerns a method of determining at least one parameter for encoding multimedia digital data organized in elementary units of data intended to be encoded according to at least one encoding mode, wherein said method comprises the following steps:—determining at least one elementary magnitude which is representative of the resources needed for decoding each elementary data unit encoded according to a different encoding mode,—determining at least one total magnitude which is representative of the resources needed for decoding a plurality of elementary data units encoded as a function on the one hand of the at least one elementary magnitude previously determined and on the other hand the number of elementary units encoded according to each of the encoding modes,—deciding with regard to the determination of at least one data encoding parameter as a function of the at least one total magnitude previously determined and a predetermined magnitude.

Abstract: In order to manage requests in at least two distinct classes, relating to multimedia data, exchanged by a communication apparatus and at least one data source connected through a communication network, at the communication apparatus:

Abstract: A method of seeking digital images from among a plurality of images stored in a database by using an example image. Each of the plurality of stored images in the database is associated with a data item representing at least one characteristic of the visual content of the image.

Abstract: The invention relates to a method of selecting a method from a set of methods of transcoding digital multimedia data, said data being liable to be transferred between at least two communication apparatuses via a communication network, the method comprising the following steps:

Abstract: The invention concerns a method of processing a request for obtaining multimedia digital data, said request having a number of descriptors characterizing it, characterized in that said method has the following steps:

Abstract: The present invention describes a method of validating parameters defining an image, each parameter being represented by one of the tops of a polygon and being able to be associated with one or more functionalities. A point (200), being able to move in the polygon (100), makes it possible to validate the parameters and the associated functionalities according to the position of this point with respect to the tops of the polygon.

Abstract: The invention concerns a method of indexing on a digital image which has been compressed or is to be compressed according to a compression method using compression parameters which influence the resulting quantity of information contained in at least part of the compressed image, the indexing requiring a predetermined quantity of information, characterised in that the method includes, prior to a step of indexing the digital image, the steps of:

Abstract: According to the invention, a method of indexing a digital image comprises the following steps: generating a first information item (H(Im)) characteristic of the visual content of the image (Im) to be indexed; generating a second information item (W(Im)) characteristic of the spatial distribution of the visual content of the image (Im) in its image plane; and associating, with the image (Im), an index (IDX(Im)) composed of the first information item (H(Im)) and the second information item (W(Im)).

Abstract: A method of seeking images, from an example image, from amongst a plurality of images stored in a database, each of the stored images being associated with an index, representing at least one characteristic of the visual content of the image, includes the following steps: a step of receiving a data item of a second type representing the location of at least one region of interest in the example image; a step of receiving, for each region of interest, a data item of a third type indicating a type of taking into account of the content of the region of interest for the seeking of images; a step of calculating an index of the example image, representing at least one characteristic of the visual content of the example image, the method of calculating this index depending on the data item of the second type and the data items of the third type; a step of calculating a similarity between the example image and each of the images from amongst at least one subset of the stored images, this similarity being calculated f

Abstract: A method of seeking images in a database, each of the stored images being associated with a data of a first type representing a characteristic of the visual content of the image, comprises the steps of: associating with each new a new image to be stored in the database, a data of a second type representing the location of at least one region of interest in the new image; receiving a data of the second type representing the location of at least one region of interest in the example image; obtaining a data of the first type associated with the example image; calculating a similarity between the example image and each of the stored images, the similarity being calculated from the data of the first type and of the second type associated respectively with the example image and with the stored image; and supplying at least one image from the database according to its degree of similarity with the example image.
