WebThe proposed fuzzy kernel is defined over a spherical volume that uses discrete bins. Discrete volumetric division can normally make a kernel vulnerable to boundary effects during learning as well as point density during inference. However, the proposed kernel remains robust to boundary conditions and point density due to the fuzzy mechanism. WebThe kernel average misorientation (KAM) is a measure of local grain misorientation that is usually derived from EBSD data. For formaly defining the KAM we denote by o i, j the orientations at pixel position ( i, j) and by N ( i, j) the set of all neighboring pixels.
