Detecting Irregular Curvilinear Structures in Gray Scale and Color Imagery using Multi-Directional Oriented Flux
We present here additional performance curves and comparative
results on the evaluated datasets. The images shown in the
links below are the maximum (or minimum) intensity
projections (MIP) of the original image stacks and those of the algorithm
results.
The results presented in the "Best Segmentations"
columns are obtained by first finding the
threshold value that maximizes the Jaccard index (equivalently the VOC measure defined in Eq.(4) of
[26]). For this, we used η=0.4, as also mentioned in the manuscript.
We then followed the procedure described in the last part of
Section 4.2 to compute the segmentations.
Finally, for stacks with floating-point voxel precision, such as the
tubularity volumes, the conversion to 8-bits (after the MIP step) is performed using the
Fiji (http://fiji.sc) software [27]. The 3D renderings under the Videos links below are created
using the publicly available Vaa3D visualization and analysis software [28].
