# MediaPipe graph to detect faces. (CPU input and inference by default.)
#
# It is required that "face_detection_short_range.tflite" is available at
# "mediapipe/modules/face_detection/face_detection_short_range.tflite"
# path during execution.
#
# EXAMPLE:
#   node {
#     calculator: "FaceDetectionShortRange"
#     input_stream: "IMAGE:image_frame"
#     output_stream: "DETECTIONS:face_detections"
#   }

type: "FaceDetectionShortRange"

# The input image, either ImageFrame, GpuBuffer, or (multi-backend) Image.
input_stream: "IMAGE:image"

# ROI (region of interest) within the given image where faces should be
# detected. (NormalizedRect)
input_stream: "ROI:roi"

# Detected faces. (std::vector<Detection>)
output_stream: "DETECTIONS:detections"
