Abstract
The present invention relates to the automatic search for an image sample (f′) in images (f) of a data base. The sample and the images are compressed using their fractal properties, in the form of relations linking their ranges (R) to area or domains (D) of the same image. According to the invention, the comparison relates to indexes registering the geometrical characteristics of these relations. Various means are proposed for permitting a profitable search and in particular a limitation of the distance between ranges and domains of the image (f).
