Root tip detection is an algorithm combining the use of structural information (root tip, segments, ...) and machine learning techniques to detect, count and classify the root tips of complex root systems.

Steps for running the executable for root tip detection

  1. Download and install Matlab compiler runtime for R2013q.

  2. Place the executable root_tip.exe and machine trained file zm_gmm4.mat and all the images in a folder together. Images should be in .tif file format. Five example files have been attached with this download.

  3. Now simply run the executable. It will read and process all the files in the folder and generate a result.txt file.

  4. The result.txt file has the counts of primary and lateral roots. It also has histogram of root tips as a function of root tip diameter. The last column is the count of root tips whose diameter could not be determined reliably.

  5. Please refer to the paper for details of implementation.
