12 Days of Thermal Riddles
« on: December 10, 2017, 11:31:40 pm »
Hey everybody!

I thought about bringing some fun into this forum so my idea was to post a little something. My idea is to post a picture for the coming 12 days up to Christmas Eve. Those pictures will be thermal pictures that I took, using various locations, targets, palettes, settings and processing to make them look nothing like a normal thermal image - but still visually pleasing.

And then everybody is invited to guess the subject! I will reveal the answer with the post for next day.

If anyone has any more ideas or want to contribute by themselves, feel free to post a reply!
Only rule I would set is that it has to be an image you took, or an image in which production you were involved with.
Anything is allowed, MSX, Visual, overlayed, picture in picture, flipping, stiching or even video/gifs. But must be mainly a thermal images done by S-/M-/LWIR or some special hyperspectral imaging system.

I don't think there will be a prize for guessing correctly, and I will not spoil it if someone has the correct guess to keep others the fun.

I will start on the 12 and will post every day through the 24th. I try to post as early as possible for my timezone (CET) .

Or maybe a cuboid with a total of 21 spots distributed over its faces.

There were ideas in different directions. But the clue to the solution was in the noisy background. A classmate actually solved it without any help. Maybe because he knows these and saw them already.

It is a sewer grate, close up. Shot in Thermal Camera + with superresolution on medium and nearest neighbor upscaling. Using the rainbow palette. Not calibrated in anyway. It was a snowy day and the sewer was warm from below. I took a few pictures but only this one made it interesting and mysterious.

I will attach a visible image of an MSX I took from a little further so you can understand it.

Wow, there are more and more people joining.

But i have to agree this was harder then I expected. It looks like a few things and he missing quality of my camera will always be an issue.

It's a vacuum cleaner tube, aluminum. Shot into it from very close. Maybe you can see the slid on the one side and then the nobs for the telescope on the opposite site. This might only look familiar to people who used this vacuum.

It is a radiometric jepg, captured in Thermal Camera+. The image was been edited in the flir tools app on Android to flip the Iron palette to make it look even stranger and was then flipped in Google photos to create a new jpg, that won't reveal the visual image once downloaded and used in any radiometric software.

It is my 3D printer after finishing a long print. The model is a vase by Devin Motes at 180% scale.

I used the lava palette and scrubbed it really far in flir tools on Android so there is no histrogramm stretching.

I am getting late again. I had some issues transferring files from my phone to my computer and therefore don't have the nice pictures yet.

number 5 was my bicycle bell it is shiny metal and therefore is reflecting the night sky - the brighter spot is a reflection of myself. I used a custom color palette made with palette generator look at the attached screenshot.

Too easy. A "Quality Street" tin with some of the sweets.

BTW, to bring it back to electronics momentarily, those make great screening cans for breadboarded circuits. A moment's work to punch a hole for a BNC or whatever.

I can take a visual image of the same subject. This image isn't really taken as a thermal capture, more as a art piece to get a nice effect.

I don't usually drop hints but for this low resolution images, it's a trick to scale them down so your brain puts it together better and maybe see a pattern in the noise.

It does make a difference to me on a lot of my images and it's an effect I haven't read a paper about yet.

I've noticed that effect too, and it extends past still images.
If I capture something with my high-speed camera at 160x80 resolution and 60 000 fps and blow it up onto a 28" 4K display, it's practically impossible to determine what is in the image(even when moving!), but as soon as it's squeezed down into a tiny thumbnail size, it's much easier to understand.

Now to write a paper and get published in a scientific journal.

Maybe it's a bit cold to be someone peeing? But it does look like that for sure!  :-DD

It's very much like it's some liquid being poured, but looking closer I don't think it is the case. There seems to be like a tube coming out with hot liquid (the "pee stream") and a couple coming in from the lower part.

I will guess it's a circuit board with some liquid cooling system for whatever chip is under the bright spot. The other small warm spots around are not pee drops but other small chips that also get a bit warm.

Yes, now with your description, I'd second that. It's another view inside the PC, looking at the liquid cooler of the CPU, and some warmer spots around probably beeing the inductors and transistors of the power supply.

I am finding this quite fascinating because to a certain extent we are seeing ourselves as others may see our hobby.

Whilst we may think that a brightly-coloured image very clearly shows an overheating widget, to a layperson it's just an abstract arrangement of pixels. I realise of course this is true for many specialist areas but to me it was revealing that the (high resolution) image of the tin of sweets was spotted immediately, whereas the lower resolution images have been the subject of mystery and debate. So even we can't always interpret results as well as we might like.

I'm not quite sure what the moral of this story might be, but it remains interesting.

The tin of sweets was easy because
  • The tin has a characteristic shape.
  • The purple sweets (brazils?) have a characteristic shape.
  • The green sweets have a characteristic shape.
  • It's almost Christmas, and tins of "Quality Street" are a British Christmas staple.

You need to work together and you will find the answer.

It is a circuit board from a radio that I repaired for a secret santa present.

You can see the freshly soldered antana wire that I held with my hand so it appears warm and the heat spread from soldering it.

The red dots in the background are other solder dots that reflect my own body.

Phillips tornado, most likely. That fused join there is one of the things that they have over other lamps, plus the more even phosphor distribution.

Feels like this was way to easy. But it just looked cool to me. I got some harder ideas for the final.

Must have been an issue on my end. I edited it back in. Sorry about that.

Does anybody know if this forum (SMF) supports any of the variants of a 'spoiler' tag? I wanted to post an answer (which I think is obvious) and didn't want to spoil it for others. Here's a disemvowelled version: t's  trch (LD  thnk) nd th rflctd bm frm tht trch.

Anybody got a syringe I can use to squeeze the magic smoke back into this?

Picked up from a lass called Theresa who moderates a forum I used to read regularly. She moderates comments by disemvowelling them, that way threads aren't broken, you can't easily read a disemvowelled comment but you can read it if you are determined and really need to read it to get the context of a thread. "Behave yourself or Theresa will disemvowel you."

A cup/mug of coffee (or tea or hot chocolate or hot water or hot milk...) with a confusing custom palette.

... With a swirl of cream.

Either that or something freshly stirred.

It's a class of tea with a spoon. I guess that pallette is really useless here and it's locked to yo fade out the surrounding.

I like to watch fluid with thermal activity. It's better then tint in water because it never ends.... I wonder how they looks with a 150k research camera with high framerates full HD resolution and high thermal resolution with no noise.

A christmas decoration (star made of straws), on a (rather cold) window. Window because of the reflection of Vipitis taking the image.

This concludes this event.

I am not really happy with how it turned out. I took more then 300 images in the last two weeks and had my camera always with me.

I planned to do more then I did in the end, but I suffered some issues with my device to transfer files from my phone to my computer for post processing an effects.

It feels like some images were far to easy while others where to hard. It's difficult to find the balance of a nice riddle which one can solve in 24hours or a group can working together.

Some things I planned included: custom pallette, rotating/flipping images, inverting palettes, limiting the Platte range, using different pallette scaling options. Videos, pip, overlays, confusing msx, stacking, stiching, photogrammetry and more. I didn't find the time due to common school and Christmas stress. If I redo this for next year I plan to prepare images and not shoot them on the day before and take them straight outta camera or just minor effects with mobile apps.

The target should be thermal phenomena like Amorphophallus titanum or lightning, clouds, meteors and not objects shot in thermal to look good.

I sadly failed to make a nice pallette that looks like the visual equivalent with red and white.... But here is me with my Santa hat wishing all of you a merry Christmas!

And thanks to everyone for participating.
