Few questions what's possible and what's not with TFJS

TensorFlow General Discussion

Hi All,

I’m pretty fresh in the world of ML. I looked at several examples of TFJS from the official repo, but this one got my attention:

For educational purposes I like to train my own model in TFJS. I want to train the model to recognize specific objects in a picture. The type of the object is only one type, so no categorization/labelling would be needed. Looking at the above example, I have few questions:

  1. I have my image dataset for the training, but few images have different dimensions. Do all images have to have the exact same dimensions? (in the example they do)
  2. For the object bounding box, can I use quadrilaterals instead of rects? (the example is using rects)
  3. Can I have multiple objects, respectfully multiple bounding boxes in a single image? (in the above example there is only one object in an image)

Thanks in advance!
