Seismic Sinusoids

  Edge Detection & Clustering

Inspiration

Data analytics most closely aligns with our team interests - theoretical computer science, machine learning, and lots of python!

What it does

We use edge detection to identify seismic activity.

How we built it

The models we used include: Sobel, Canny, fast Fourier transform, K-means clustering, The packages we used: openCV, scikit learn,

Challenges we ran into

While the appropriate curves are easily detectable by eye, it was hard to get our algorithms to do the same. We encountered many false positives, specifically with horizontal lines (whereas the correct curves followed a more sinusoidal pattern).

Accomplishments that we're proud of

We sifted through many different computer vision models to see which detected curves the best. We ended up using a combination of a few filters.

What we learned

Various edge detection techniques and filters.

What's next for Seismic Sinusoids

Find a way to detect less sharp edges. Come up with better clustering techniques.
