The requirement is to write a program to decode each captcha images listed below(Please find the attachment).
The basic idea is that is to find the pattern and rules of the images, write a algorithm to trim the image, and then use some of the existing OCR library(like tesseract-ocr) to do the final process. but you will still be able to find your own solution.
Your can use any language and library, but the only restriction is the program must be able to run at linux. which means you can't use any Microsoft related technology(e.g. .NET, C#).
Your program must expose a command line instance(JAR file also can) in order to make our internal integration friendly.
