Class opencv_dnn.Layer

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.javacpp.opencv_dnn.Layer

All Implemented Interfaces:

AutoCloseable

Enclosing class:

opencv_dnn

@Namespace(value="cv::dnn")
@NoOffset
public static class opencv_dnn.Layer
extends Pointer

\brief This interface class allows to build new Layers - are building blocks of networks. Each class, derived from Layer, must implement allocate() methods to declare own outputs and forward() to compute outputs. Also before using the new layer into networks you must register your layer by using one of \ref LayerFactoryModule "LayerFactory" macros.

Constructor Detail

opencv_dnn.Layer

public opencv_dnn.Layer(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

blobs

@ByRef
public opencv_dnn.BlobVector blobs()

List of learned parameters must be stored here to allow read them by using Net::getParam().

blobs

public opencv_dnn.Layer blobs(opencv_dnn.BlobVector blobs)

_allocate

@Name(value="allocate")
public void _allocate(@Const@ByRef
                       opencv_dnn.BlobPointerVector input,
                       @ByRef
                       opencv_dnn.BlobVector output)

\brief Allocates internal buffers and output blobs with respect to the shape of inputs.

Parameters:

[in] - input vector of already allocated input blobs

[out] - output vector of output blobs, which must be allocated This method must create each produced blob according to shape of \p input blobs and internal layer params. If this method is called first time then \p output vector consists from empty blobs and its size determined by number of output connections. This method can be called multiple times if size of any \p input blob was changed.

forward

public void forward(@ByRef
           opencv_dnn.BlobPointerVector input,
           @ByRef
           opencv_dnn.BlobVector output)

\brief Given the \p input blobs, computes the output \p blobs.

Parameters:

[in] - input the input blobs.

[out] - output allocated output blobs, which will store results of the computation.

inputNameToIndex

public int inputNameToIndex(@opencv_core.Str
                   BytePointer inputName)

\brief Returns index of input blob into the input array.

Parameters:

inputName - label of input blob Each layer input and output can be labeled to easily identify them using "%[.output_name]" notation. This method maps label of input blob to its index into input vector.

inputNameToIndex

public int inputNameToIndex(@opencv_core.Str
                   String inputName)

outputNameToIndex

public int outputNameToIndex(@opencv_core.Str
                    BytePointer outputName)

\brief Returns index of output blob in output array.

                    String outputName)

name

@opencv_core.Str
public BytePointer name()

Name of the layer instance, can be used for logging or other internal purposes.

name

Type name which was used for creating layer by layer factory.
