Now if you could get this to fill in a text box for me when I try to buy concert tickets you'd make a fortune.

Hi guys!
mladen, of course it's the computer:) it's my python script
(nothing python specific; the code can be easily rewritten in C++).
Reading an image file -> Converting it to the greyscale mode -> Populating a 2D array of bytes.
Then analyzing the matrix, pixel by pixel, and so on.
All is based (or rather inspired by) on the idea of so called Stroke Filter Response,
but I do it in much my own way.
Note: the code d-o-e-s n-o-t r-e-c-o-g-n-i-z-e texts.
I don't even know what those Chinese words on my pics mean (seems the very first one means "http").
As an intro to the subject a quote from an article of engineers from Samsung Advanced Institute of Technology:
quote:
... For example, from the Canny edge image shown
in Fig.1 (a), it is so difficult to find the text even for human
eyes. Besides the high complexity of text localization, we
think that the fundamental reason of these problems is that
no researcher finds the distinctive features of text. That is to
say, no one answers the basic question: what on earth is
text? Intensity-similarity CCA, edge, corner or texture
features are only the necessary conditions of text, as shown
in Fig. 1(b). Although recently someone uses Adaboost to ...
Teeg, flumpie, I like you like it :)

yeah canny filter can be quite helpful. try bluring an image before you apply it. i found it gave better results.

What I need is a good test set of images.
They say there is e.g. Microsoft test set of 46 images.
Mladen, if you were (are) in the subject, where can I see your results?
I can't find anywhere someone's else after-detecting-pics, to see and compare
PS
I don't know what Canny filter is :)

No! I've never seen this article (now I'm downloading it).
I have 3 or 4 other pdf-s thru which I just browsed and catched the main/basic idea/KEYWORDS.
Then I applied my own grey matter :) Forgot: at first I tried to implement a chinese algorithm,
based on stroke filter, without much success (due to my poor understanding of its (algo) steps)
