FiberFit is a portable Python application that analyzes fiber orientation in 2D images to quantify fiber distribution in tissues. It uses computer vision and libraries like NumPy and SciPy to process multiple images and export results as PDFs and CSVs. With a graphical user interface, it provides live progress updates and runs cross-platform on Windows and Mac OS X without additional software.

2. What it does?
• The mechanical properties of tissues in the body largely depend
on the underlying fibrillar network
• Fibrillar network can be described in terms of fiber orientation
distribution
• FiberFit quantifies fiber orientation distribution, thus allowing
researchers to gain deeper insights into tissue modeling and
injury repair

3. Program Features (1)
• Python application that uses computer
vision to analyze fiber orientation in 2-D
grayscale images
• Utilizes NumPy and SciPy libraries* to
perform image analysis
• User Interface was built using Qt 5
bindings for Python

4. Program Features (2)
• Processes multiple images
• Exports result of the analysis in PDF (utilizes open-source Python library) and csv
• Live progress bar, which updates user about status of the image analysis (utilizes
threading)
• Runs on Windows and Mac OS X without installing additional software
• Free to download at https://coen.boisestate.edu/ntm/fiberfit/

5. Used Technologies
• pyPDF2
• SciPy
• NumPy
• pandas
• Python standard libraries (os, time, sys)
• PyQt5
• cx_Freeze
• threading
• otool
• git

6. Reflection
• 2nd author of a research paper (currently under review)
• 1st author of a scientific manuscript for a research conference (currently under
review)
• Joined the project during summer of my freshman year
• Practiced agile development by constantly modifying the application based on
feedback from a graduate student and lab director
• Solved unfamiliar problems (i.e. relinking binaries in Mac OS X)
