Is there a way to convert the craft flow output to arrows instead of the heat map it produces?

I didn't find craft-chairs.pth. could you upload it if possible? Thank you!

Dear authors,

Thanks a lot for your excellent work! It helps a lot.

How to visualize the optical flow given two consecutive images?
For example, given these two images (https://github.com/askerlee/craft/tree/main/imgs).

Thanks in advance, and have a nice day.

Best,

Hello, @askerlee!
Thank you for sharing this wonderful work!

I have a question about CRAFT in Table 1 of C + T / Autoflow.
There are two commands when training CRAFT (train-craft-f2full.sh), so I do not know what command should I use to obtain the performance in Table 1.
Specifically, between these below two commands.

1. python3 train.py --name craft-things --stage things --validation sintel --output results/things/craft-f2full --restore_ckpt results/chairs/craft-f2full/craft-chairs.pth --num_steps 120000 --lr 0.000125 --image_size 400 720 --wdecay 0.0001 --gpus 0 1 --batch_size 6 --val_freq 10000 --print_freq 100 --mixed_precision --craft --f2 full --setrans

2. python3 train.py --name craft-autoflow --stage autoflow --validation sintel --output results/autoflow/craft-f2full --num_steps 200000 --lr 0.000125 --image_size 488 576 --wdecay 0.0001 --gpus 0 1 --batch_size 6 --val_freq 10000 --print_freq 100 --mixed_precision --craft --f2 full --setrans

Thanks in advance!

Hi @askerlee , nice work for Optical Flow estimation.
There are some problems when using optical flow for warping, I try to use flow_viz.warp_flow in your code for warping, but got the following result:

What may be the problem? Look forward to your reply.
