How do you implement feature extraction for large-sized images? #3

Hello, great paper and work,thank you .

How do you implement feature extraction for large-sized images? The paper is limited to 1024 pixels, and the zoom factor cannot be greater than 1.

Hi @ahong007007

The approach has no problem with large-sized images. The command line is as follows:

python extract.py --model model.pt --images image.jpg --top-k 5000 --min-size 0 --max-size 9999 --min-scale 0.3 --max-scale 1.0

Note: In my implementation, a zoom factor = 1 means full-image size, and = 1/2 means half the resolution.
