Methods
-
dispose(
) → void -
Releases the underlying native resources. Idempotent: calling it more
than once is safe, but the object must not be used after dispose.
inherited
-
dump(
) → String -
forward(
{String outputName = ""}) → Mat - Forward runs forward pass to compute output of layer with name outputName.
-
forwardAsync(
{String outputName = ""}) → Future< Mat> -
forwardLayers(
List< String> names) → VecMat - OpenVINO not supported yet, this is not available ForwardAsync runs forward pass to compute output of layer with name outputName.
-
forwardLayersAsync(
List< String> names) → Future<VecMat> -
freeNative(
) → void -
Frees the native resources owned by this object. Subclasses implement the
concrete free logic here; callers must use dispose instead.
override
-
getInputDetails(
) → (VecF32, VecI32) - Returns input scale and zeropoint for a quantized Net. https://docs.opencv.org/4.x/db/d30/classcv_1_1dnn_1_1Net.html#af82a1c7e7de19712370a34667056102d
-
getInputDetailsAsync(
) → Future< (VecF32, VecI32)> -
getLayer(
int index) → Layer - GetLayer returns pointer to layer with specified id from the network.
-
getLayerNames(
) → List< String> - GetLayerNames returns all layer names.
-
getLayerNamesAsync(
) → Future< List< String> > -
getPerfProfile(
) → (int, VecF64) - GetPerfProfile returns overall time for inference and timings (in ticks) for layers
-
getPerfProfileAsync(
) → Future< (int, VecF64)> -
getUnconnectedOutLayers(
) → List< int> - GetUnconnectedOutLayers returns indexes of layers with unconnected outputs.
-
getUnconnectedOutLayersAsync(
) → Future< VecI32> -
getUnconnectedOutLayersNames(
) → List< String> - getUnconnectedOutLayersNames
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
setInput(
InputArray blob, {String name = "", double scalefactor = 1.0, Scalar? mean}) → void - SetInput sets the new value for the layer output blob.
-
setInputAsync(
InputArray blob, {String name = "", double scalefactor = 1.0, Scalar? mean}) → Future< void> -
setPreferableBackend(
int backendId) → void - SetPreferableBackend ask network to use specific computation backend.
-
setPreferableTarget(
int targetId) → void - SetPreferableTarget ask network to make computations on specific target device.
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
