Affine transformations create class artifacts #31

Closed Rob174 closed 3 years ago

Interpolation on labels cause class shifts:

On this image at the origin there was probably only the brightest class of value 2, but with interpolation (due to augmentations), the class 1 has been added (darker gray pixels)

Slow solution but add precision

Create the augmented patch directly with points of annotations
