I don’t believe TFLite can resize images, but I’d like to know this as well. I worked through this example: https://github.com/EdjeElectronics/TensorFlow-Lite-Object-Detection-on-Android-and-Raspberry-Pi/blob/master/TFLite_detection_webcam.py, and the author uses OpenCV to resize each frame rather than TFLite.
Is there a reason that you can’t use a pooling layer to do the job, at least for integer scalings?
Pooling could definitely work. I don’t know if it’s any more or less computationally efficient than other resizing methods, though.
