    do you know to detect ANY pattern? if so, arrow wont be difficult.

    Now if you are very new, start with the basics - like detecting the colours, circles etc.
    .... I didnt do it ! ....

    there are no "commands" to detect shapes. you need to implement algorithms to detect them.


    I highly recommend you play around with image processing basics before you jump into shape detections or hough transforms.

    Matlab is fine, in case you dont have matlab, try opencv. its a library, and easy to use.

    Obviously you use what you need out of the book. Read the book in your past time to understand the underlying logic.
