Week 2 Wednesday (More Computer Testing)

Today, we were once again tasked with calculating the variation from the exact location to the location that the previous program was calculating, as well as to the method that we were implementing. Although the camera was in a constant position for the entirety of the video clip that we were analyzing, we utilized the same methods that we would have used for a broadcast film with a moving camera. Thus, we truly are comparing the three fixed focal length camera to the broadcast system.

I finished my measurements that compared the exact location to what the freshman's program predicted. I used a ruler to determine a scale in the x and y directions for both images shown above. Then, I used these values to find coordinates for the location of a single person in both frames, with the same origin. Then I calculated the distance between these coordinates to find how far off the freshman's calculations were.

I am done with that process, so I now have to begin calculating how far off our predictions are. We once again use a scale to find the exact coordinates, and we used Image J to find the predicted coordinates. It is hard to remain unbiased in this process, but we must in order to ensure the accuracy of our data.
