It’s a deeper issue than image processing though. This is just an allegory (and I’m proud to FINALLY have figured out a good process for turning bmp into vector)
Does the data drive the thresholding though?
I don’t think it does. A decent algorithm / NN process can do a good autothresholding but the judgement call of utility is still set or approved by human.
You’re learning while teaching.
That’s what good teachers do. The most crucial network forms inbetween your network and the network of the database. It’s a dance, a relationship. More like gentle coaxing than demanding.
This thing I just did today ties in. Started out trying to make a Bmp into a Vector by hand but ended up stumbling into a deeper issue: setting a threshold. Doorway between rooms. Categories. State Rights vs Individual Rights. Take your pick of threshold, it’s always for us to set and decide.
There are a lot of them. But I don’t know of any that’s universal. I’m hoping to come across a list of them with code so I can compare the thought processes behind them.
ImageJ has an auto-thresholding that has a lot of options and names the algorithms. That’s how I got the montage. (very hard to find a program that will just give me a threshhold montage but ImageJ (or Fiji, which is ImageJ with all the good plugins) has it.
