Quantified Adaptive Fusion of Spectral Bands


We find results similar to those of conjunctive and adaptive fusions. However, we do not find unclassified pixels. While conjunctive fusion imposes the unanimity of the sources to decide to assign a pixel to a class, quantified adaptive fusion needs only a majority of sources in agreement to carry out the classification of the pixel. If none of the other sources formulates an opinion, then only one source will be enough to choose to assign the pixel to such or such class .Searching the greatest consensus among the sources, but without imposing the unanimity, makes it possible to classify the pixels that conjunctive fusion could not classify.

However, the result remains very close to that of conjunctive fusion because quantified adaptive fusion, such as we modified it, preserves a largely conjunctive behaviour on the spectral bands for which the unanimity is always reached (except for 1.21% of the pixels).
