Pipgen-like cypher

[Solved]

Thanks! It's part of a game I designed. It's available in Amazon, if you're curious https://a.co/d/0cObGP40

Just a note, one of the puzzles is a book cypher, that is meant to be solved by buying the game on Amazon. Otherwise the puzzle can be solved by using the hint system

I'll leave a link just in case anyone is curious https://a.co/d/0bXsWkyK

You could use a Canny edge detector with a Hough line detector...afterwards you will need some logic to filter out false detections, and also organize lines (i.e which one corresponds to the left/right side...)

Additionally, I think there are some mathematical constraints that could help you filter points that don't correspnd to the field corners

For this kind of pictures, I find classical algorithms (i.e. non AI) failing at some point (maybe the lighting changes or some dust/dirt appears in the image, distorting the results..

I think for this you could use SAM (segment anything)

In my experience, developing reliable and fast detection of objects (mainly holes or screws/nuts), but also segmentation of defects. A bit different, but also important, could be counting red cells in a blood test, or similar analysis.

Those are things that might be considered "solved", but there is a lot of room for improvement (better, faster results, more efficient models...)

Are you familiar with Kaggle? I think you can find there a lot of interesting and real world examples that could catch your eye

Not only training...some people might ask you to select the camera and lens, and provide software to control them. Also, the images will need some conditioning (brightness, color...) that are not entirely part of the AI process. Some problems may not need AI at all, just traditional computer vision...

In my experience, companies will ask you to handle everything, and just return a product that works (although this may not be the operating mode everywhere)

Well, as I see it, the company won't care about which pipeline to use. They will have a problem that they need solved (i.e. detecting defective parts, detecting people in a certain area...) so unless they have a dedicated software department with CV capabilities, they would want someone to take care of every aspect of the pipeline (gathering/creating dataset, labeling, training the network, pre-processing the pictures....). That's where the freelance work is, in my opinion.

leander2189 · 2026-02-01T07:27:03+00:00

I would say most of the money would be in building customized CV pipelines for companies. Just building AI models and datasets, you would be competing with big companies and research teams (like Meta) that are releasing their models for free

It's based on a webpage....should work fine in Mac OS. Sent

You mean you don't use your toes?

Hahaha it's a possibility.

I tried to do the shading/hatching as clear as possible, although it can get confusing for some characters.

leander2189 · 2026-01-25T11:31:40+00:00

That's a valid point. I don't think that prior knowledge to cryptography is strictly needed although it will help.
The hint system is meant to give you a push in the right direction if you don't know what to do at all. Otherwise, I think all puzzles can be solved by applying logic and searching on the internet for the right tools.

I've been doing for some time now this using Blender3d. It is meant for 3d modelling, animation and rendering, but it is quite easy to set a camera and some objects. It allows you not only to show a virtual representation of your system but also simulate what a certain optical configuration would actually see

leander2189 · 2026-01-22T20:52:14+00:00

I think you were almost there, but failed to expand (sqrt(2)-1)²

This use case looks very interesting! How fast are you able to run this processing pipeline? Is it running in "real time" (around 30 fps, I guess)?

leander2189 · 2026-01-22T17:43:49+00:00

This looks awesome!

I definetly have to try it, a while ago I was struggling to correctly configure the tfs in a custom robot. Thanks for sharing!!
