    Default OCR System for Recognise Characters in an Application Form

    For my final year project i hope to develop an Character Recognition System which is once the image of a application form is submitted to the system it should extract all the details including his picture and should display it in the form.

    Are there any java in built API to recognize characters or if not is it necessary to use Advance Algorithms.. Or do i have to use Math Lab for this..

    If there are sample codes please be kind to publish for me...

    Please guide me it will be a great help for me to success my project in given time.

    what have you done so far dear?'coz i think there is no one to bother 'bout your project.

    i guess your project is something like:

    1. fetch an image of a character which resides in the hard disk(you can start with java swing to build your UI & then go through the image methods; use imageIo to read & image Icon to display your character in the application form)

    2. after that you need to binarize the image(representing in 0 & 1)

    3.pre processing- this includes noise removal,thinning,scaling,etc.

    4. feature extraction- you have to extract some features of each character image with the help of that we can identify the character.

    5.final recognition

    as per my knowledge you can proceed in this way for your "Character Recognition System".if i am wrong then just ignore this post.

    good luck

    sanyan751 has developed an excelent list of task you should
    consider for your project. Step 4 caught my eye because I
    developed such an algorithm. It is close to 400 lines of code.
    Also, I developed it around 'clean images', so step 3 was not
    a consideration.

    I value this list because it fits so well into what I have planned
    for my project, yet I know nothing of sanyan751.

    I guess, in all of this is a WARNING (Will Robinson!):
    This is a very large project for a final year project.
    Maybe you should choose only one of these steps
    for your project.

    Java Code:
    1. fetch an image of a character which resides in the hard disk
       (you can start with java swing to build your UI & then go through the
       image methods; use imageIo to read & image Icon to display your
       character in the application form)
    
    2. after that you need to binarize the image(representing in 0 & 1)
    
    3. pre processing- this includes noise removal,thinning,scaling,etc.
    
    4. feature extraction- you have to extract some features of each
       character image with the help of that we can identify the character.
    
    5. final recognition
    
    as per my knowledge you can proceed in this way for your
    "Character Recognition System".if i am wrong then just ignore this post.
    
    good luck
