Basic Video Processing

In this activity we try to obtain relevant scientific data from a video. We use a video of a free falling object to try to obtain the acceleration due to gravity g.

We obtain  and crop the relevant frames from the video:

To make the processing easier, we binarize the images:

Then using a center of mass algorithm, we reduce the objects into points and graphed their location with respect to time^2:

comparing the obtained equation to 0.5gt^2 + vt we can see that 0.5g = 4.6624, or g =9.3248m/s^2.

This was an easy activity so I give myself a 9/10
