I have it working locally so I could create pull request with what I have @i-aki-y . I also have MixUP working as you suggested: ``` mosaic1 = mosaic_aug(image=image1, image_cache=image_cache,...

> This means that some bboxes have zero or minus heights. > Did you get this error only when you used mosaic transform? Yes. I had multiple augmentations in my...

Feel free to check out my MixUp implementation [here](https://github.com/albumentations-team/albumentations/pull/1409) @i-aki-y . Any feedback is appreciated. It works nicely with this Mosaic implementation :smile:. I am going for `CutMix` :rocket:

Btw, I have implemented this in a slightly different manner. ```python class Mosaic(DualTransform): def __init__( self, height, width, replace=True, fill_value=0, bboxes_format="coco", always_apply=False, p=0.5, ): super().__init__(always_apply=always_apply, p=p) self.height = height self.width...

But this should be avoided by `bbox_params=A.BboxParams(format='coco', min_area=1)` right @i-aki-y? I tried this but didn't work for me

Any updates on Mosaic for Albumentations?

Any update on this?

+1, would be nice to be able to use `py-motmetrics` instead of `trackeval`

For those who wonder and want to give it a try: Official HOTA in `trackeval`: https://github.com/JonathonLuiten/TrackEval/blob/12c8791b303e0a0b50f753af204249e622d0281a/trackeval/metrics/hota.py#L9 Should go here: https://github.com/cheind/py-motmetrics/blob/beb864a56d6055047c4d6e015188fcc24aca05b7/motmetrics/metrics.py
