Validates and builds the {@link GestureRecognizerOptions} instance. @throws IllegalArgumentException if the result listener and the running mode are

Width of the frame in pixels.

Removes the entry for an iterator.

Height of the frame in pixels.

Swaps width and height.

Create using a vector of TAG:<index>:name.

A number of calculators use the non-CC methods on GlCalculatorHelper even though they are CalculatorBase-based.

Adds a packet to a graph input stream.

SetSameAs should be available only in the cases when node's input is Any, output is Any, but input & output should have the same type.

Returns true if the Packet is empty.

Sets the {@link RunningMode} for the face detector task. Default to the image mode. face detector has three modes: <ul> <li>IMAGE: The mode for det

Creates an empty Packet, for which IsEmpty()==true and Timestamp()==Timestamp::Unset(). Calling Get() on this Packet leads to CHECK-failure.

Serializes a MessageLite into FieldData.message_value.

Returns the image height.

Returns the image width.

Returns the image pixel data as an unwritable numpy ndarray. Realign the pixel data to be stored contiguously and return a reference to the u

Number of channels, equal to the number of rows in each Matrix.

Returns the image / video format.

CPU getters.

Gives access to node input streams: `CalculatorGraphConfig::Node::input_stream`. Usage pattern: ``` other_node.Out("OUT")[0].ConnectTo(node.In("IN")[

Total number of available samples over all blocks.

Returns a label associated with a node. A leaf node will have the MSB set and thus return an invalid label.

TODO: maybe this should be size(), like in a standard C++ container?

The embedding results for each head of the model.

* Sets a value or an array of values into the file content. * @param array A typed or untyped array of values to set. * @param offset The index

Checks if a valid file descriptor is wrapped.

Returns the byte offset between a pixel value and the same pixel and channel in the next row. Notice, that for alignment reasons, there may be unused

* Converts JavaScript string input parameters into C++ c-string pointers. * See b/204830158 for more details. Intended for internal usage.

Returns the header Packet, if one was set for the corresponding OutputStream in the upstream Calculator's Open method. May be called in Calculator::Op

Returns a shared copy of the Packet. <p>This is essentially increasing the reference count to the data encapsulated in the native mediapipe pa

Get a const pointer to the underlying image data.

Creates a Java packet from a native mediapipe packet handle. Returns a Packet from a native internal::PacketWithContext handle.

Splits dataset into two sub-datasets with the given fraction. Primarily used for splitting the data set into training and testing sets. Args

Euclidean norm. For integer T, correct only if Norm2 does not overflow.

Gives access to node output streams: `CalculatorGraphConfig::Node::output_stream`. Usage pattern: ``` node.Out("OUT")[0].ConnectTo(other_node.In("IN"

Creates an `Image` object from an image file. Args: file_name: The path to the image file. Returns: An `Image` object. Rais

Creates a string packet.

Returns the {@link AndroidPacketCreator} associated to the {@link TaskRunner} instance.

Makes a rectangle given the corner (x, y) and the size (width, height).
