Hi, i'm looking for a library function that allows to perform perspective transformation on an image. something like cvGetPerspectiveTransform in OpenCV. i have 4 AR markers and an image printed between them. when filmed, the image is skewed. i need to rectify it:
there is a function in nyartoolkit called pickupMarkerImage that does what i need, but seem to work only on marker itself, not the area around it. any hints appreciated.
