Thank Skotz for your very good lib.

I'm working on an captcha which I can work on the filter to have clean final image but currently I don't see how to train the solver and get db?

Actually I have just read previous Issue ticket but not sure how to implement the training properly.

Such as we need to change script to Train & Save instead of Solve? TRAIN, "I:\qqq" SAVE, I:\qqq\new.db"

I do see we need a test pool of as big as possible images but how can tell Solver which is good which is bad?

On your script in previous Issue: TRAIN, "qqq" FULLTEST, "qqq", "test.txt"

I even see the result: TOTAL CORRECT: 213 (213/266 = 80.08%)

Is that we are manually calculate or the lib support that?

Thank for your support in advanced.

My script. SetMode, all SetupSegmenter, BLOB, 30, 40, 4 SetupSolver, BVS, "ABCDEFGHIJKLMNOPQRSTUVWXYZ", 50, 60

DefinePreconditions Resize, 400, 140 RemoveSmallBlobs, 10, 4, 4 BlackAndWhite Grow Grow Median EndPreconditions

Solve, %IMAGE%

I just put together some new documentation to walk you through how to train a model. Please let me know if any parts are confusing and I'll try to update it accordingly.

Check out the solver walkthrough.

Thanks!
