Changes

By knowing the change in pixel locaton betwen photos, as well as th angular displacment, a value for pixel change per mrad in the xdiection can be determined.  This proess is then repeaed for the y direction.  Once these tweo parameters are known, the video analyss can be used to fin both frequency nd amplitude.

The same process used for the calibration images can be used to analyze the motion of the center of the lens flair over im.  Becaue of the number of images involved in a video at 1200 fps, a batching process was developed to automate the proces.  First, a built in Linux program, ffmpeg, is used to separate the images from the video.  Next, the automtion script is applied to the folder contaning the video stills.  This script uses the same code as the image analysis, but loops the search pocess through a large group of imags.
