Function Documentation

vil_warp()

template<class sType , class dType , class MapFunctor , class InterpFunctor >

void vil_warp	(	const vil_image_view< sType > &	in,
		vil_image_view< dType > &	out,
		MapFunctor	mapper,
		InterpFunctor	interp
	)

Warp an image under a 2D map.

The size of the output map and the mapper defines the region of the input image to be scanned.

Parameters

mapper,is	the inverse of the mapping from the input image's co-ordinate frame to the output image's frame. i.e. out() = in(mapper(x,y)). It should be a functor with a signature void mapper(double x_in, double y_in, double* x_out, double* y_out);
interp,is	an interpolator, with a signature similar to S vil_bilin_interp_safe(const vil_image_view<T>&, double, double, unsigned)

Note that if you want to store a warp with an image to create a registered image, the vimt library (in contrib/mul/vimt) provides efficient registered images with transforms up to projective.
