RE: MurgaLua Number OCR

Did some reworking of this, and now I've got something more presentable:
Not everything works yet, performance is abysmal (difficult to get a good dataset), etc etc. But the important idea is there!

So what this does is permit the user to train the ANN by drawing numbers (3 times each by default, but you can repeat training) and afterwards you can detect the drawn character (or should be able too Tongue).

The detection rate is bad, I guess because a box is either on or off, so there is no "gray" zone around the lines, there are no transformations, normalizations, whatever...

So the wish list for this little snip for people that want to contribute:

  • preview drawing
  • Better data usage (middeling out the different tries)
  • counters at each preview
  • suggestions, comments, ideas, ...

Writing this, I found some need to have some guidelines for the gui programming concerning good programming practices, like limiting use of globals, and whether it's possible to access widgets by their parents like window.button1:label() or something.

Oh well, hope someone can do something useful with this!

Regards,

Jan-Pieter
