Abstract: The present invention concerns a method of encapsulating images in a file, wherein the method comprises determining a grouping type based on a capture mode of the images; generating a grouping data structure describing the images as a group, the grouping data structure comprising image identifiers of the images of the group; and embedding the grouping data structure, the grouping type and the images in the file.

Abstract: A method of encapsulating entities in a file, wherein the method comprises for at least one entity: generating a grouping data structure associated with at least one of the entities, and indicating that the at least one of the entities belong to a same group; encapsulating the grouping data structure and the entities in the file; wherein the grouping data structure is a proprietary grouping data structure comprising an universally unique identifier identifying the type of the proprietary grouping.

Abstract: A method of encapsulating image data in a media file, the image data being related to a main image to be generated based on a plurality of sub-images, wherein the method comprises: obtaining the plurality of sub-images, each sub-image being provided in at least one version; generating descriptive metadata for describing the main image and the plurality of sub-images; encapsulating the plurality of sub-images and the descriptive metadata in the media file; wherein the method further comprises: generating a progressive information defining a set of consecutive progressive steps for generating a version of the main image, each progressive step being associated with a set of sub-images versions required to generate the version of the main image; and embedding the progressive information in the descriptive metadata.

Abstract: The invention concerns a method for emulsifying, without grinding, a silicone in water in the presence of a surfactant, at a temperature less than 60° C. and under shearing at less than 100 s−, comprising steps which consist in: a) preparing a primary oil-in-water emulsion including said surfactant and said silicone under shearing at less than 100 s−, by adding an aqueous phase to an oily phase comprising said silicone; b) enriching the resulting emulsion with an enriching oily phase comprising said silicone by mixing, under shearing at less than 100 s−, and c) if required, repeating one or several times the operation at step b) until the desired concentration in surfactant and/or silicone in the final emulsion is obtained and/or until the desired particle size distribution is obtained.
