<p>In the appendix of <a href="https://arxiv.org/pdf/1911.09070.pdf" rel="nofollow noreferrer">https://arxiv.org/pdf/1911.09070.pdf</a>, there is a section describing the image resolution for training.</p>
<p>Depending on the speed/performance trade-off, you may choose a smaller resolution for detecting your objects, like 640x640, or increase the resolution to 1024x1024 if you have smaller objects in size; regardless of the case, preserve the aspect ratio when you resize your image.</p>
EfficientDet D0 512x512 image size
<p>what is the best image size should I use for training an EfficientDet D0 512x512 for object detection.
I have image size varying from 500x500 to 2000x2000 is this okay for training the EfficientDet D0 512x512?</p>
