An initial image is subjected to a plurality of segmentations into uniform components by using various criteria to identify and isolate several series of objects constituted by segmented thumbnail images associated with geometrical descriptors for boxes that cover said objects, the results of the segmentation methods are fused, numerical values are used to characterize each object thumbnail image that results from fusion, and each of the thumbnail images is compared with indexed thumbnail images in an indexed database containing a set of textual descriptions for everyday elementary objects. The list of textual descriptions of everyday elementary objects matching the object thumbnail images that result from the segmentation and fusion operations is provided together with pertinence levels.

Process for the automatic creation of a database of images accessible by semantic features

In the method, correlated achromatic single-plane images are subjected to a plurality of operations for segmenting them into uniform components on the basis of different criteria. The results of the various segmentation operations for each of the processed correlated images are analyzed in order to generate cores constituted by zones presenting high certainty as to the existence of objects. The resulting cores are compared and those zones which correspond to more than some determined threshold of the various cores are conserved as indicating the presence of an object. The previously processed images are subjected to a weighted summing operation in order to obtain a first result image containing the uniform component cores. The first result image is then subjected to coloring followed by binarization in order to obtain a second result image containing the uniform components, and the individualized objects are extracted from the image.
