    You'll need OCR software.

    However if you are trying to crack "capcha" codes we don't have those discussions here. It is against policy to support such efforts.

    first you must convert picture to array which has 0 and 1 values for pixel.
    in another words picture must converted into bitmap that has only white & black color.

    second you must distinguish the letters in these array

    third you must find the letter form for each seperated bitmap

    these are the main steps to work.
    You can do while you think that you can do

    If you think my answer solve your question, please rate it.

    SNIPER...

    dilettante told you that you need OCR software and thats basically it. Even with that it becomes extremely difficult because the text in a picture cannot always be determined. If the picture with text is like the one you posted and the text font won't change you might be able to do it like BlueRose suggested but you will need pattern matching (ie, you need a bitmap of each possible character in the picture of the same size and font) once you have extracted out the black pixels.

    Anything I post is an example only and is not intended to be the only solution, the total solution nor the final solution to your request nor do I claim that it is. If you find it useful then it is entirely up to you to make whatever changes necessary you feel are adequate for your purposes.
