template<class T>

void vimt_find_image_troughs_3x3	(	vcl_vector< vgl_point_2d< unsigned > > &	troughs,
		vcl_vector< T > &	trough_value,
		const vil_image_view< T > &	image,
		unsigned	plane = 0,
		bool	clear_list = true
	)			[inline]

Return image co-ordinates of all points in image strictly below their 8 neighbours.

Parameters:

clear_list,:

If true (the default) then empty list before adding new examples

		bool	clear_list = true
	)			[inline]

Return image co-ordinates of all points in image strictly below their 8 neighbours.

Parameters:

clear_list,:

If true (the default) then empty list before adding new examples

template<class T>

void vimt_find_world_troughs_3x3	(	vcl_vector< vgl_point_2d< double > > &	troughs,
		const vimt_image_2d_of< T > &	image,
		unsigned	plane = 0,
		bool	clear_list = true
	)			[inline]

Return world co-ordinates of all points in image strictly below their 8 neighbours.

Parameters:

clear_list,:

If true (the default) then empty list before adding new examples

template<class T>

bool vimt_is_trough_3x3	(	const T *	im,
		vcl_ptrdiff_t	i_step,
		vcl_ptrdiff_t	j_step
	)			[inline]

True if pixel at *im is strictly below its 8 neighbours.

The image pixel (first argument) should *not* be a border pixel!
