Image size for Google AutoML Training

[tindoantrong]

Hi, I have some images which are lager than  1024 pixels by 1024 pixels.
Following this document: https://cloud.google.com/vertex-ai/docs/image-data/object-detection/prepare-data
Image size should be 1024 pixels by 1024 pixels suggested maximum. If I resize images, the quality of images is low.

What should I do?
Thank you and
Regards
