Week 4 Wednesday (Testing)



After working out the kinks in the method of comparison yesterday, today was simply spent working on finding and analyzing the data. I took about 30 frames from the set of fixed focal length camera data that is not filtered. The filtered data is what the RIT freshman had used to calibrate the system, so the numbers on the back of the jerseys are visible to the human eye. Using that data would inherently have skewed the data, making it seem like there are more pixels revealing jersey number than there really are.

Thus, I utilized the unfiltered data. I ended up using the clippings of other teams. This decision should not matter as the numbers are placed in the same location, and for our pixel analysis, should not vary based on team. I used the bounding polygon box on Image J and searched how Image J can find the area inside the box. Pressing [M] allows numerous data values to be shown in a results window. One of those data values is the area. I finished calculating the pixel values for the broadcast and fixed focal length camera systems for 30 frames each. Now, I will determine if that is sufficient data and the differences between the two systems.
