| virtual void vimt_image_pyramid_builder::build | ( | vimt_image_pyramid & | , |
| const vimt_image & | |||
| ) | const [pure virtual] |
Build pyramid.
Implemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, vimt_scale_pyramid_builder_2d< T >, and vimt_gaussian_pyramid_builder_2d_general< T >.
| virtual vimt_image_pyramid_builder* vimt_image_pyramid_builder::clone | ( | ) | const [pure virtual] |
Create a copy on the heap and return base class pointer.
Implemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, vimt_scale_pyramid_builder_2d< T >, and vimt_gaussian_pyramid_builder_2d_general< T >.
| virtual void vimt_image_pyramid_builder::extend | ( | vimt_image_pyramid & | ) | const [pure virtual] |

| vcl_string vimt_image_pyramid_builder::is_a | ( | ) | const [virtual] |
Name of the class.
Reimplemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, vimt_scale_pyramid_builder_2d< T >, and vimt_gaussian_pyramid_builder_2d_general< T >.
Definition at line 39 of file vimt_image_pyramid_builder.cxx.
| 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_scale_pyramid_builder_2d< T >, and vimt_gaussian_pyramid_builder_2d_general< T >.
Definition at line 46 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_gaussian_pyramid_builder_2d< T >, vimt_dog_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_gaussian_pyramid_builder_2d< T >, vimt_dog_pyramid_builder_2d< T >, and vimt_scale_pyramid_builder_2d< T >.
| virtual void vimt_image_pyramid_builder::print_summary | ( | vcl_ostream & | os | ) | const [pure virtual] |
Print class to os.
Implemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, vimt_scale_pyramid_builder_2d< T >, and vimt_gaussian_pyramid_builder_2d_general< T >.
| virtual double vimt_image_pyramid_builder::scale_step | ( | ) | const [pure virtual] |
Scale step between levels.
Implemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, vimt_scale_pyramid_builder_2d< T >, and vimt_gaussian_pyramid_builder_2d_general< 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_gaussian_pyramid_builder_2d< T >, vimt_dog_pyramid_builder_2d< T >, and vimt_scale_pyramid_builder_2d< T >.
| short vimt_image_pyramid_builder::version_no | ( | ) | const |
Version number for I/O.
Reimplemented in vimt_dog_pyramid_builder_2d< T >, vimt_gaussian_pyramid_builder_2d< T >, vimt_scale_pyramid_builder_2d< T >, and vimt_gaussian_pyramid_builder_2d_general< T >.
