# CHANGES:
|
|
# - `input_video` is ImageFrame (ImageFrameToGpuBufferCalculator converts it into GpuBuffer)
|
|
# - Add ImageTransformationCalculator and rotate the input
|
|
# - Remove AnnotationOverlayCalculator
|
|
|
|
# Tracks and renders pose + hands + face landmarks.
|
|
|
|
# ImageFrame

# Throttles the images flowing downstream for flow control. It passes through
|
|
# the very first incoming image unaltered, and waits for downstream nodes
|
|
# (calculators and subgraphs) in the graph to finish their tasks before it
|
|
# passes through another image. All images that come in while waiting are
|
|
# dropped, limiting the number of in-flight images in most part of the graph to
|
|
# 1. This prevents the downstream nodes from queuing up incoming images and data
|
|
# excessively, which leads to increased latency and memory usage, unwanted in
|
|
# real-time mobile applications. It also eliminates unnecessarily computation,
|
|
# e.g., the output produced by a node may get dropped downstream if the
|
|
# subsequent nodes are still busy processing previous inputs.
