For a month, I worked on tracking the motion of cilia in zebra fish given data that came from Professor Ankur Saxena of the University of Illinois at Chicago. Here is the website that describes his research goals and progress. I highly suggest you check out the interesting material.
Over the summer, a few interns and I compiled individual research reports to be sent to Dr. Saxena regarding our progress. Given images of the cilia over a small time frame, I primarily focused on finding the key points of the images and using them to track the motion. The entire process of brightening, rotating and cropping, filtering, and detecting the key points of each image is detailed in the report, shown here.
