[magick-users] Auto alignment of shifted images

[Johnson Lau]

Dear All,

I have two images.
One is a blank questionnaire : http://www.comminn.net/ftp/a.jpg
Another one is a completed questionnaire: http://www.comminn.net/ftp/b.jpg
I have a program which could help me to enter the data automatically.
However, as you can see, b.jpg is slightly shifted and not completely
match a.jpg, and the data entry software could not tolerate. Since I
have thousands of such questionnaires, and they have different type of
slight shifting and rotation, I need a solution which could help me
align all images automatically. I would like to know if ImageMagick or
any other software could do this? Thanks very much!

Regards,

Johnson Lau
