Method and device for segmentation of images by texture analysis.

摘要

The automatic image segmentation device according to the invention comprises a processor of the data associated with a network of automata organized into three levels, the inputs of each of the programmable logic controllers are weighted by the coefficients that are adjustable; the number of programmable logic controllers of the first level is equal to the number of characteristic values calculated from the observation windows used firstly in a set of examples of zones of different textures: their training by the network makes it possible to adjust the weighting coefficients of the programmable logic controllers of the network, until all the examples of the same texture lead to a same configuration, which is characteristic of this texture, at the output of the network. & br / the segmentation of an image then consists, on the basis of sets of characteristic values calculated on the zones of images to be analyzed, to analyze the output of the network in order to deduce therefrom the texture of the zone. & br / application to the segmentation of aerial images or of medical images, for example, and more generally to any type of images in which the regions are discriminable by their texture.
