Do we need a post-processing on the depth data?

Hi @JuliaPoo , many thanks for providing this Python wrapper for Google's Mediapipe. But I'm wondering if we need to do some post-processing on the depth data rather concatenate them to processed 2D landmarks for outputting directly? Since I believe the scale of raw hand 2D landmarks data is unrelated to the original image, and so we need to do some post-processing to let the hand 2D landmarks project onto the original full-size image. Should we also do that on the depth data? Because it looks not correctly if plotting the 3D hand landmarks result on a 3D plot. Thanks.
