## Detailed Description

Layer factory allows to create instances of registered layers.

## Member Typedef Documentation

## § Constructor

typedef Ptr<Layer>(* cv::dnn::LayerFactory::Constructor) (LayerParams &params)

Each Layer class must provide this function to the factory.

## Member Function Documentation

## § createLayerInstance()

static Ptr<Layer> cv::dnn::LayerFactory::createLayerInstance | ( | const String & | type,
|  | LayerParams & | params
| ) |  |
| static

Creates instance of registered layer.

Parameters

  type | type name of creating layer.
  params | parameters which will be used for layer initialization.

Note
  Thread-safe.

## § registerLayer()

static void cv::dnn::LayerFactory::registerLayer | ( | const String & | type,
|  | Constructor | constructor
| ) |  |
| static

Registers the layer class with typename `type` and specified `constructor`. Thread-safe.

## § unregisterLayer()

static void cv::dnn::LayerFactory::unregisterLayer | ( | const String & | type | ) |
| static

Unregisters registered layer with specified type name. Thread-safe.
