Description
PR on https://github.com/ultralytics/ultralytics/pull/4250
I suggest a customized mosaic method
_mosaic3, based on_mosaic9in augment.py,class Mosaic.I usually prefer to use Mosaic to make my model robust to real world's data, but I found a critical flawness in my project. The project uses a dataset with a ground view and all the objects in dataset places on the floor.
But when training with a mosaic4 or mosaic9, mAP goes a bit higher but it also produce FP(False Positive) predictions. So I customized the existing mosaic methods not to make undesirable height position noises.
It not only takes no additional calculation compared to existing methods, but also written very similar with them. I don't think that undesirable noise problem is just minor one in certain case.
For these reasons, it would be a good option to add this method.
