This is neat, but it's less "How to Train a YOLO4" and "How to put your data into [our product that abstracts the training of YOLO4 behind the scenes so you don't even have to know what you're doing]." That's totally fine, to be clear, but the title makes it seem like one will learn about training YOLO4 models, when instead one is really learning how to use the roboflow dashboard to put images into their system, the fact that it happens to be YOLO4 under the hood is incidental.
I always see these kind of things for Object detection in 2D images. What about for example feature detection in 3D meshes/ DICOM scan data? Are there equivalents to the 2D models?
