Function Documentation

void vl_svmdataset_delete

(

VlSvmDataset *

self

)

Delete the object.

Parameters:

self	object to delete.

The function frees the resources allocated by vl_svmdataset_new(). Notice that the wrapped data will *not* be freed as it is not owned by the object.

Definition at line 164 of file svmdataset.c.

VlSvmAccumulateFunction vl_svmdataset_get_accumulate_function

(

VlSvmDataset const *

self

)

Get the accumulate function.

Parameters:

self

object.

Returns:

a pointer to the accumulate function to use with this data.

Definition at line 260 of file svmdataset.c.

void* vl_svmdataset_get_data

(

VlSvmDataset const *

self

)

Get the wrapped data.

Parameters:

self

object.

Returns:

a pointer to the wrapped data.

Definition at line 179 of file svmdataset.c.

vl_size vl_svmdataset_get_dimension

(

VlSvmDataset const *

self

)

Get the dimension of the wrapped data.

Parameters:

self

object.

Returns:

dimension of the wrapped data.

Definition at line 201 of file svmdataset.c.

VlHomogeneousKernelMap* vl_svmdataset_get_homogeneous_kernel_map

(

VlSvmDataset const *

self

)

Get the homogeneous kernel map object.

Parameters:

self

object.

Returns:

homogenoeus kernel map object (or NULL if any).

Definition at line 215 of file svmdataset.c.

VlSvmInnerProductFunction vl_svmdataset_get_inner_product_function

(

VlSvmDataset const *

self

)

Get the inner product function.

Parameters:

self

object.

Returns:

a pointer to the inner product function to use with this data.

Definition at line 291 of file svmdataset.c.

vl_size vl_svmdataset_get_num_data

(

VlSvmDataset const *

self

)

Get the number of wrapped data elements.

Parameters:

self

object.

Returns:

number of wrapped data elements.

Definition at line 190 of file svmdataset.c.

VlSvmDataset* vl_svmdataset_new	(	vl_type	dataType,
		void *	data,
		vl_size	dimension,
		vl_size	numData
	)

Create a new object wrapping a dataset.

Parameters:

dataType	of data (float and double supported).
data	pointer to the data.
dimension	the dimension of a data vector.
numData	number of wrapped data vectors.

Returns:

new object.

The function allocates and returns a new SVM dataset object wrapping the data pointed by data. Note that no copy is made of data, so the caller should keep the data allocated as the object exists.

vl_svmdataset_delete

Definition at line 138 of file svmdataset.c.

void vl_svmdataset_set_homogeneous_kernel_map	(	VlSvmDataset *	self,
		VlHomogeneousKernelMap *	hom
	)

Set the homogeneous kernel map object.

Parameters:

self	object.
hom	homogeneous kernel map object to use.

After changing the kernel map, the inner product and accumulator function should be queried again (vl_svmdataset_get_inner_product_function adn vl_svmdataset_get_accumulate_function).

Set this to NULL to avoid using a kernel map.

Note that this does *not* transfer the ownership of the object to the function. Furthermore, VlSvmDataset holds to the object until it is destroyed or the object is replaced or removed by calling this function again.
