Over the years, a number of software tools have been developed to facilitate the analysis of PhenoCam imagery. Links to these tools are provided below. Not all of these tools are kept up-to-date; we recommend contacting the original developer with questions or requests for troubleshooting help.
xROI is a tool to delineate Region of Interests (ROI's) and extract time series data from digital repeat photography images which was develped by Bijan Seyednasrollah.
You can find the GitHub repository for the package here. The paper describing this software was published by Seyednasrollah et al. (2019)
This is a Python package that provides command line scripts for analyzing PhenoCam imagery. A version of this package is what is used to generate the standard PhenoCam data products and the time series displayed on the PhenoCam web site.
You can find the latest documentation for the package here.
You can find the GitHub repository for the package here.
This package is also available on PyPi.
The phenopix R package includes routines to handle each of the steps involved in processing PhenoCam imagery. It enables the user to: draw a region of interest (ROI) on an image; extract red green and blue digital numbers (DN) from a seasonal series of images; depict green-ness index trajectories; fit a curve to the seasonal trajectories; extract relevant phenological thresholds(phenophases); extract phenophase uncertainties. The package is documented in the paper by Filippa et al. (2016).
A package for automated image classification for images with snow has been developed by Jason Jewik. There is a short document describing the process here and a GitHub repository with the code. This code was developed while Jason worked in the Stutz Lab with then graduate student Zoe Pierrat.
The PhenoCam images from many sites (using Stardot cameras) include an image overlay containing potentially useful information such as date, time, temparature and exposure values. Some experimental MATLAB code for extracting this information using OCR techniques has been developed by Don Aubrecht:
The PhenoCam GUI application is available as a pre-compiled MATLAB® program (no license required). It is available for both Windows and Mac OSX platforms. To run the application you need to first install the MATLAB runtime compiler (bundled in the download). Included in the download are instructions for running the application.
For users with a MATLAB license a source code version of the GUI tool is provided. This version has been run on Windows, Mac OSX and Linux systems.
