What is the best way to find tick marks or cross on a a4 paper forms. The forms can change (position of the ticks or cross can change).

For object detection template matching and training a HAAR classifier are two options that I have come across. Which should be preferred and when?

Thanks

it's called "Optical Marker Recognition", and you can google it.

OMR can be trained for detecting crosses and ticks?
