Library to split picture

[damien.raemy]

Hello,

I search a Java library that we can use to split an image automatically. The idea is that scan a letter and use this library to split and analyze the elements of the letter (content, sender address, receiver address, ...).

Does anyone know a library that I could use?

Thanks.

The BufferedImage class has a method that will get sub images out of an image. Use that with a set of x,y,width, height values and an array should do it.

Thanks for your answer.

I think I haven't well explained my problem: I don't want to extract a subimage. I want a library that calculate and give me coordonate (x, y, width, height) of each element in the image. After, I will can use your method to "cut" the image.

For example, look at this picture:


I want a library that analyze the picture and return me the separated elements:
- The sender address
- The recipient address
- The stamp.

Do you have an idea?

How is an element of an image defined?
Is there a white background with groups of other colored pixels for the elements?
You want to draw a rectangle around each of the groups of non-background colored pixels where the background colored border is greater than a certain number of pixels.

How is an element of an image defined?

An element is defined because it has white space around it (see my example).

My project is:
- Registered letter
- Split the scanned image in elements (my question): address, barecode
- Archive some elements (barecode) and read and store texts in a database using an OCR

Are you going to write the code to do the scan to find the elements?

[damien.raemy]

No, it's too complicate and should take too much time. I'm searching an OpenSource library that do that.

Ok, good luck.
