http://code.google.com/p/zxing/ has a very nice api for scanning barcodes in various formats
if you are interested in decoding a barcode yourself, have a look at this processing example

Getting handwritten text from images

How to extract handwritten text from images, like bank form images, in Java?
I tried to using Tesseract, OCR, GOCR but didn't working for me. Are there any other ways to extract handwritten text from images in Java which works at least 80-90%?
Question with links to libraries
I don't think JAVA natively supports this function, so you gotta use libraries.
There was a question which asked for working libraries and the general consent was: you won't get a 80-90% working recognition in a free and open source library.
Anyway, you can try this, as it is a wrapper for Tesseract.

How to read images using Java API?

I have been using a piece of Software that works as a Reading Scanner. Basically it retrieves text from images. Is there any API for Java that would enable programmatically recognize text contained in images, in particular .tiff to regular text? Or is there any Java class that would help ... I do not know how to start
This question was answered in previous post.

This type of problem is called Optical Character Recognition or OCR. The first Google result for "Java OCR" looks promising: http://sourceforge.net/projects/javaocr

Read Character Value from image through java program

Hi All,
As showing i have an image with fields Username & City & Work as in the image. I just want to read these Character fields value from this image with java program.
If any one have any idea about this please let me know
thanks
You can google with Java Character recognition through image and there is also good way to do this with this example. this jar you can use as for testing
Tess4J, a Java wrapper of Tesseract engine, can recognize such images (after rescaling to 300 DPI).
You should start looking into character recognizing libraries like shown here. also, look at this question here
To read the image you can use BufferedImage: http://docs.oracle.com/javase/tutorial/2d/images/loadimage.html
Once you have loaded the image you can run an OCR module to get its text. Here are some examples of OCR software sorted from better to worst: ABBYY (but it is not free), Tesseract, Java OCR, Asprise...
And that is all !!

How can I convert image sequence to quicktime movie?

I have been searching on this. I Need to build an independent utility that should:
Convert image sequence to .mov format
Take input from user and display it inside the mov.
I plan to do this using Java since this is a cross platform language.
How to do it?
See JpegImagesToMovie.java it requires the x-plat version of the JMF (or more importantly jmf.jar).
For a more modern alternative, look to JFFMPEG (JMF with more formats & encodings).
I have earlier used XUGGLER for making videos from image frames. It is easy to use XUGGLER with the help of the comprehensive tutorials available here. You can also add audio to the video generated from the image frames.
Xuggler supports a large number of video codecs and video container formats so you will have the option of creating the video in different formats, leave alone .mov. Hope this helps. I can post my own code for this utility if required.
