Part names

[compvizard]

When I specify the part names ['left_upper_arm_front', 'right_upper_arm_front'], the mask highlights the back of the sitting lady's arms. When I switch to ['left_upper_arm_back', 'right_upper_arm_back'], the mask highlights the front of the arms instead. Same issue for lower arms.

Thank you for raising the issue.

Just adding CLI commands to reproduce it potentially:

python -m tf_bodypix \
    draw-mask \
    --model-path=https://storage.googleapis.com/tfjs-models/savedmodel/bodypix/resnet50/float/model-stride16.json \
    --show-output \
    --threshold=0.75 \
    --mask-alpha=0.5 \
    --colored \
    --parts left_upper_arm_front right_upper_arm_front \
    --source \

To be honest I am having difficulty telling front and back apart. What image are you using?

The part names seem to match tfjs-models. Would you say it is any better with tfjs-models?

I’m using the same image: serious-black-businesswoman-sitting-at-desk-in-office. I get the feeling that “front” means where the arms face outwards away from the shoulders and “back” means where the arms face inwards towards the armpit and chest. I had expected “front” to be part of the arms facing forward and “back” to be the parts facing backwards. So perhaps this is not a bug, just differences in interpretation. Thanks for the response, anyway.

Do you think the issue can be closed? (If there are inconsistencies with the bodypix model in tfjs-models then I could look into it.)
