    2727The GPS in the device gives a standard source of time. PTP uses this time to timestamp packets with the time the computer receives them, and to sync all the local clocks on our computer network to the GPS standard time.

    5866This week was shortened to a considerable margin to the point where we couldn't make much progress. However, we were able to plan for the following weeks by creating many artificial videos of varying amounts of noise as well as a plan to create histogram to plot the number of occurrences each hex byte appeared in order to visualize how noise affects packets using the Python library Matplotlib.

    8391These histograms show the number of occurrences in the 5-sec camera footage for each type of colored pixel value with no noise.
    84      -Red/Green
    85           -The number of occurrences is mostly 0 because most of the camera footage is dark, though there are some high red/green pixel values due to some white light being present when the LED flashes on.
    86      -Blue
    87           -The occurrences of blue pixel values is significantly higher because the LED emits blue light.
     92     - Red/Green
     93          - The number of occurrences is mostly 0 because most of the camera footage is dark, though there are some high red/green pixel values due to some white light being present when the LED flashes on.
     94     - Blue
     95          - The occurrences of blue pixel values is significantly higher because the LED emits blue light.

    8997The RGB histograms were made without noise, compared to the histogram on the bottom when there was significant amount of noise present. These results show that the amount of noise in our camera can heavily affect our data set.
