Abstract

The invention discloses a method implemented by computer for semantically describing the content of an image comprising the steps consisting of receiving a signature associated with said image; receiving a plurality of groups of initial visual concepts; the method being characterised by the steps consisting of expressing the signature of the image in the form of a vector comprising components referring to the groups of initial visual concepts; and modifying said signature by applying a filtering rule that is applied to the components of said vector. Developments describe, in particular, filtering rules that involve filtering by thresholds and / or by intra-group or inter-group order statistics, partitioning techniques including the visual similarity of the images and / or the semantic similarity of the concepts, and the optional addition of manual annotations to the semantic description of the image. The advantages of the method in terms of sparse and diversified semantic representation are presented.

Description

technical field

[0001] The present invention relates generally to the technical field of data mining, and in particular to the technical field of automatic annotation of image content. Background technique

[0002] A "multimedia" document includes a variety of information by etymology, usually related to different sensory or cognitive abilities (for example, related to vision or hearing). A multimedia file can be, for example, an image accompanied by a "markup", that is to say by annotations, or correspond to a web page comprising images and text.

[0003] Digital files can typically be divided into several "channels" of information, which can include, for example, textual information (eg, derived from OCR character recognition) and visual information (eg, illustrations and / or photographs identified in the file). A video can also be divided into several such channels: a visual channel (e.g., the frames of a video), an audio channel (e.g., an audio channel), a textual channe...
