Measure Skeleton Length¶
Measure the length of a skeleton using the algorithm from
Niemisto, A., Dunmire, V., Yli-Harja, O., Wei Zhang, and Shmulevich, I. (2005). Robust quantification of in vitro angiogenesis through image analysis. IEEE Transactions on Medical Imaging 24, 549–553.
The aspect ratio of a pixel is considered to be one. Lengths are calculated from the middle of one pixel to the middle of another pixel.
To install the tool, drag the link Measure_Skeleton_Length to the ImageJ launcher window. Save it under /plugins/tools in the ImageJ installation and restart ImageJ.
Using the tool¶
Create a skeleton from your image. You can do this by first creating a mask for example with the "threshold adjuster" and then running Process>Binary>Skeletonize. Press the "measure skeleton tool-button". The length of the skeleton will be written to the results table.
