dynamic input shape yunet model face detection about opencv_zoo

[fengyuentau]

Hello @erfansafaie , yes, with our code and model you can use various kinds of input scales for face detection. Note that you need to set input scale each time you do a inference on an image with a different input scale from the previous one:

opencv_zoo/models/face_detection_yunet/yunet.py

Lines 49 to 50 in 05fe0a4

	def setInputSize(self, input_size):
	self._model.setInputSize(tuple(input_size))

opencv_zoo/models/face_detection_yunet/demo.py

Lines 96 to 98 in 05fe0a4

	# Inference
	model.setInputSize([w, h])
	results = model.infer(image)
