Top: The fiber-to-bundle coherence FBC measure is determined via kernel density estimation. A Brownian motion kernel is used (shown left), which is defined on the space of positions and orientations. The streamlines are color-coded according to their FBC measure, scaled from high (blue) to low (white). Bottom: The RFBC is computed using a sliding window of size α and produces a single value for each streamline. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
