This roll installs Cascaded Hierarchical Model (CHM)
https://www.sci.utah.edu/software/chm.html
Description from site above:
Cascaded hierarchical model is an image segmentation framework, which learns contextual information in a hierarchical framework. At each level of the hierarchy, a classifier is trained based on downsampled input image and outputs of previous levels. Our model then incorporates the resulting multi-resolution contextual information into a classifier to segment the input image at original resolution. We repeat this procedure by cascading the hierarchical framework to improve the segmentation accuracy.

Dependencies
- The matlab roll must be installed on hosts that run this application
- The nbcr roll must be installed on hosts and on the node that builds this roll
A successful build will create the file chm-*.disk1.iso
To install, execute these instructions on a Rocks frontend:
rocks add roll *.iso
rocks enable roll chm
(cd /export/rocks/install; rocks create distro)
rocks run roll chm | bashThe roll installs chm and a configuration file in:
/opt/chm -- CHM application
/opt/modulefiles/applications/chm -- environment modules
/etc/ld.so.conf.d/chm.conf -- paths to matlab shared librariesOnce installed this roll can be tested by running /opt/chm/test_chm_install.sh script. This script will
run the two main programs for chm CHM_train.sh and CHM_test.sh and verify they generate output and don't
fail. If successful, script exits with 0 exit code and success message.
Warning: Accuracy of the answer is not checked.
Example of test:
$ /opt/chm/test_chm_install.sh
Running test of chm programs CHM_train.sh and CHM_test.sh (5 minutes)
Creating /tmp/testchm0d783641-c584-4814-b6fc-2727673df30e
If this script fails the directory may need to be removed manually
