Anyone here know about in-browser ML tools for building models using images? In this case, we'd like to annotate ("draw" where relevant lines are present) some subset of an image corpus to build a model, and to do so interactively, feeding this training data into some easily configurable NN tool. Is there anything like this that is simple from a UI point of view?

Kind of like ScaleAI? https://scale.com/rapid#how-it-works

Not exactly. I want something simpler, that just does images (and something that's not a commercial product). The intended use is for academic work and, more or less, annotating images and using ML to "find the lines" on scanned forms

Not sure, but you might find something among these - https://github.com/heartexlabs/awesome-data-labeling

I think labelbox may be open source

This is a little prototype I whipped up with a Pytorch model behind a web socket. Interaction is done via click events on a HTML canvas.

Thanks all!
