When analyzing video frames captured for monitoring the IV dripping process, dew droplets could exist in the image. We discussed image processing methods to remove the dew droplets from the background, including computing the difference between frames and averaging to get a proper background image. We also discussed various methods to keep the temperature of some areas of the inner surface of the drip chamber to be above the dew points in order to prevent dew droplets formation or to remove them. In the end we showed how video of the dripping process could be shown on external display(s) for devices enclosing the drip chamber inside.
