             abstract = "In the framework of the Image Foresting Transform (IFT), there is 
                         a class of connectivity functions that were vaguely explored, 
                         which corresponds to the non-smooth connectivity functions (NSCF). 
                         These functions are more adaptive to cope with the problems of 
                         field inhomogeneity, which are common in MR images of 3 Tesla. In 
                         this work, we investigate the NSCF from the standpoint of 
                         theoretical and experimental aspects. We formally classify several 
                         non-smooth functions according to a proposed diagram 
                         representation. Then, we investigate some theoretical properties 
                         for some specific regions of the diagram. Our analysis reveals 
                         that many NSCFs are, in fact, the result of a sequence of 
                         optimizations, each of them involving a maximal set of elements, 
                         in a well-structured way. Our experimental results indicate that 
                         substantial improvements can be obtained by NSCFs in the 3D 
                         segmentation of MR images of 3 Tesla, when compared to smooth 
                         connectivity functions.",
