JavaScript implementation of the main algorithm in

• Daniel Lemire, Martin Brooks and Yuhong Yan, An Optimal Linear Time Algorithm for Quasi-Monotonic Segmentation. International Journal of Computer Mathematics 86 (7), 2009. http://arxiv.org/abs/0709.1166

This code was used in the preparation of the following manuscript :

• Perrine Ruer, Charles Gouin-Vallerand, Le Zhang, Daniel Lemire, and Evelyne F. Vallières, An analysis tool for the contextual information from field experiments on driving fatigue,CONTEXT 2015, 2015.

Java version

The code was ported in Java for the Android platform.

Usage

The script is just meant a demo. Please read the code and adapt it to your own purpose.

Assuming you have a mac, you can run it in a command line...

sudo ln -s /System/Library/Frameworks/JavaScriptCore.framework/Versions/Current/Resources/jsc /bin/jsc
chmod +x samplescript.js
cat VehicleRunInfo.json | jsc samplescript.js 

If you have gnuplot installed:

cat VehicleRunInfo.json | jsc samplescript.js > test.data && gnuplot test.gnuplot
