body pose model?

[fm64hylian]

Hi, maybe this does not go here but is it possible to have something similar to 68 face landmarks but with full body or upper body? I am developing on unity and face detection is pretty much covered, however for body pose(my target is android) I haven't had any luck. I have tried ARcore(not compatible) AR foundation, OpenCV python, barracuda using an onnx model (not compatible) tried openpose, posenet, etc but I haven't found any pretrained body model similar to faces yet.

In this asset:
https://assetstore.unity.com/packages/tools/integration/opencv-plus-unity-85928

there is an example that use face recognition, and by using the face and eye haar cascades plus the 68 face annotation landmarks it creates a real time recognition example. I want to replicate this for a full body, or upper body using body annotations with the fullbody and upper body haar cascades, is it possible? my goal is to create a fitting room using AR for android

sorry if it's not okay to post it here, I've been researching about it for 2 weeks and it's driving me crazy.
it doesn't have to be that many landmarks, I'm ok with 13 or something

thank you

I was also facing a similar problem, I tried to train a shape predictor for pose estimation, but I couldn't make it work either, especially for weird poses (it turns out some humans are really flexible)

Dlib has this loss layer: loss_mean_squared_per_channel_and_pixel, which is what they use in this approach to estimate landmark heatmaps: Simple Baselines for Human Pose Estimation and Tracking.
When used with a ResNet50 backbone and an input size of 224x224, you can easily get inference times below 10 ms on a GPU, however, I don't think that would be suitable for an Android app, where there's no CUDA...

Thank for your reply, it is indeed difficult without cuda(I am using windows with an Intel chip which makes it even worse) I haven't dig too much in models but I tried to run some like the body25 from open pose, I am completely new to deep learning so I kind of need a lead, is it possible to create a rough body pose model within one week? what would you recommend? I know that unity supports nn files as well, should I dig on tensorflow maybe? (they gave me 3 weeks to make this app lol)

I am afraid I am not in a position to give you advice on how you should do your work.
However, I will say that, given the amount of time you have left, you'd be better off using some already trained solutions like this one: https://github.com/edvardHua/PoseEstimationForMobile

thanks so much! I will definetely give it a look. Another super noob question, the steps for training the model are there but, is it there like a generated file that can just drag to read it with opencv or similar? or do I have to compile something to generate that? I still don't understand how most pretrained models work
