Function Documentation

vl_lbp_delete()

void vl_lbp_delete

(

VlLbp *

self

)

Parameters

self	object to delete.

vl_lbp_get_dimension()

vl_size vl_lbp_get_dimension

(

VlLbp *

self

)

Returns

dimension of the LBP histograms. The dimension depends on the type of quantization used.

See also

vl_lbp_new().

vl_lbp_new()

VlLbp* vl_lbp_new	(	VlLbpMappingType	type,
		vl_bool	transposed
	)

Parameters

type	type of LBP features.
transposed	if true, then transpose each LBP pattern.

Returns

new VlLbp object instance.

vl_lbp_process()

void vl_lbp_process	(	VlLbp *	self,
		float *	features,
		float *	image,
		vl_size	width,
		vl_size	height,
		vl_size	cellSize
	)

Parameters

self	LBP object.
features	buffer to write the features to.
image	image.
width	image width.
height	image height.
cellSize	size of the LBP cells.

features is a numColumns x numRows x dimension where dimension is the dimension of a LBP feature obtained from vl_lbp_get_dimension, numColumns is equal to floor(width / cellSize), and similarly for numRows.
