HI could you give an example of how to specify this in the script if i'm using deepflow?

Thanks

manuelruder commented 8 years ago

I would recommend to create an auxiliary script run-deepflow.sh <file1> <file2> <output>. There you can write something like this:

<deepmatching_path>/deepmatching-static $1 $2 | <deepflow_path>/deepflow2-static $1 $2 $3 -match

(If you don't want to or can't use the static builds, then you have to remove the -static suffix of course. But the static build should be sufficient in most cases.)

The you can just specify: flowCommandLine="./run-deepflow.sh"

@manuelruder @Sugarbank you can add -nt 0 to deepmatching-static $1 $2 to enable multithreading. By the way, is there a GPU version for DeepFlow ?

manuelruder commented 8 years ago

There is no GPU version of DeepFlow. If you want to speedup the process, you could compute the optical flow in parallel to the torch script. Then it's anyway beneficial to run it on CPU, because the torch script mainly runs on GPU. Just call ".\makeOptFlow.sh ..." in a different process than "th artistic_video.sh ...".

Hi,Sorry this is a bit newbie but...Where do I set the path to the optical flow utilities in the makeOptFlow.sh file? it say "# Specify the path to the optical flow utility here." Sorry for the stupid questions.

@Sugarbank if you use the newest version of this script there is nothing you have to change any more. Just download and place deepflow and deepmatching in the same directory as the scripts, as said in the updated readme. In case you want to use your own algorithm, check out line 3 where it says flowCommandLine="...".
