Function Documentation

vil_gauss_filter_5tap() [1/2]

template<class srcT , class destT >

void vil_gauss_filter_5tap	(	const srcT *	src_im,
		std::ptrdiff_t	src_istep,
		std::ptrdiff_t	src_jstep,
		destT *	dest_im,
		std::ptrdiff_t	dest_istep,
		std::ptrdiff_t	dest_jstep,
		unsigned	nx,
		unsigned	ny,
		const vil_gauss_filter_5tap_params &	params,
		destT *	work,
		std::ptrdiff_t	work_jstep
	)

Smooth and subsample src_im to produce dest_im.

Applies 5 pin filter in x and y, then samples every other pixel. Assumes dest_im has sufficient data allocated

vil_gauss_filter_5tap() [2/2]

template<class srcT , class destT >

void vil_gauss_filter_5tap	(	const vil_image_view< srcT > &	src_im,
		vil_image_view< destT > &	dest_im,
		const vil_gauss_filter_5tap_params &	params,
		vil_image_view< destT > &	work
	)

Smooth a src_im to produce dest_im.

Applies 5 element FIR filter in x and y.
