void cudacore_pyr_build_lowpass_5	(	const int *	dsrc,
		int *	dtmp,
		int *	dres,
		const int	depth,
		const env_size_t	w,
		const env_size_t	h,
		env_size_t *	outw,
		env_size_t *	outh
	)

Core lowpass5 pyramid computation.

this runs fully in device memory and assumes you have allocated it. Note that level 0 is also not computed here. See env_pyr_build_lowpass_5_cuda() for what you have to do to prepare the work and collect the results.

void env_pyr_build_lowpass_5_cuda	(	const struct env_image *	image,
		env_size_t	firstlevel,
		const struct env_math *	imath,
		struct env_pyr *	result
	)

Direct CUDA-accelerated replacement for env_pyr_build_lowpass_5.
