Too much steam in your anime?

Well, Overmix is here with a dehumidifier to solve your problem. Too damp? Run it once and watch as your surroundings become clearer.

Your local hot spring before:

and after:

Can’t get enough of Singing in the rain? Don’t worry, just put it in the reverse and experience the downpour.

Normal rainy day:

The real deal:

This is another multi-frame approach, and really just as simple as using the average. Since the steam lightens the image, all you have to do is to take the darkest pixel at that position. (In other words, the lighter the pixel is, the more likely it is to be steam.) Since the steam is moving, this way you use the least steamy parts of each frame to gain a stitched image with the smallest amount of steam.

If we do the opposite, take the brightest pixel, we can increase the amount of steam. That is not really that interesting, but the second example shows how we can uses this to bring out features that would otherwise be treated as noise. We could also combine it with the average approach using a range, to deal with the real noise, but I did this for fun so I didn’t go that far.

While this is a fairly simple method, it highlights that we can use multiple frames not just to improve quality, but also to analyze and manipulate the image. I have several neat ideas I want to try out, but more about those when I have something working.
