void vimt_correlate_2d	(	const vimt_image_2d_of< srcT > &	src_im,
		vimt_image_2d_of< destT > &	dest_im,
		const vil_image_view< kernelT > &	kernel,
		vgl_point_2d< double >	kernel_ref_pt,
		accumT	ac
	)		[inline]

Correlate kernel with src_im, keeping track of transformations.

dest is resized to (1+src_im.ni()-kernel.ni())x(1+src_im.nj()-kernel.nj()) (a one plane image).

On exit dest(x,y) = sum_ij src_im(x+i,y+j)*kernel(i,j)

dest_im.world2im() is set up so that vimt_bilin_interp(dest_im,p) is the convolution of the kernel with the source image when the kernel's reference point is placed at p in src_im
