vimt_image_pyramid_builder::vimt_image_pyramid_builder ( )

Dflt ctor.

Definition at line 16 of file vimt_image_pyramid_builder.cxx.

vimt_image_pyramid_builder::~vimt_image_pyramid_builder ( ) [virtual]

Destructor.

Definition at line 22 of file vimt_image_pyramid_builder.cxx.

virtual void vimt_image_pyramid_builder::extend ( vimt_image_pyramid & ) const [pure virtual]

Extend pyramid.
The first layer of the pyramid must already be set.
Implemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d_general< T >, and vimt_scale_pyramid_builder_2d< T >.

bool vimt_image_pyramid_builder::is_class ( vcl_string const & s ) const [virtual]

Does the name of the class match the argument?.

Reimplemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d_general< T >, and vimt_scale_pyramid_builder_2d< T >.
Definition at line 49 of file vimt_image_pyramid_builder.cxx.

virtual int vimt_image_pyramid_builder::max_levels ( ) const [pure virtual]

Get the current maximum number levels allowed.

Implemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, and vimt_scale_pyramid_builder_2d< T >.

virtual vimt_image_pyramid* vimt_image_pyramid_builder::new_image_pyramid ( ) const [pure virtual]

Create new (empty) pyramid on heap.
Caller responsible for its deletion
Implemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, and vimt_scale_pyramid_builder_2d< T >.

virtual void vimt_image_pyramid_builder::set_max_levels ( int max_l ) [pure virtual]

Define maximum number of levels to build.
Limits levels built in subsequent calls to build() Useful efficiency measure. As build() only takes a shallow copy of the original image, using max_l=1 avoids any copying or smoothing.
Implemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, and vimt_scale_pyramid_builder_2d< T >.
