Illustration of a case where the considered pixel i lies at the intersection of two filaments with different orientations. Top: subregion of the initial map A, highlighting the filaments detected with FilDReaMS (dark blue lines) and when computing expectation over RHT orientation function (red line). Bottom: orientation function obtained with RHT (left) and FilDReaMS (right), showing the filament orientation angles derived in both cases.
