  In this paper we are proposing the use of Kaniadakis entropy in the bi-level
thresholding of images, in the framework of a maximum entropy principle. We
discuss the role of its entropic index in determining the threshold and in
driving an "image transition", that is, an abrupt transition in the appearance
of the corresponding bi-level image. Some examples are proposed to illustrate
the method and for comparing it to the approach which is using the Tsallis
entropy.
