Hi, I want to run mrflow.py for my frames. It is written that initialization with flows and rigidity image gives more accurate estimate. I want to ask if I give parameter --no_init, mrflow.py would still use CNN for estimating rigidity or not.

hello and thanks for the code!
are you planning to publish your code to generate the rigidity maps ?
or are there existing projects to do that already available .. ?
thanks in advance

I got this error when trying to run the program on my own frames. I ran with the --no_init option and provided three frames as specified. My images basically have a more or less still background with moving human subject (essentially the first few seconds of this video from Ellen Degeneres as a test for our later use cases)

==== EXCEPTION ====

Exception: TooFewStructureMatches

I struggle to get some decent results on real life pictures/videos.
Blur looks like a significant issue bt maybe I a not using the algo properly. I am just usin the test syntax line from the readme so far.
Can you give some tweaks/advices to get better results if possible?

I attach the best test I got so far but I did expect some better rigidity map given the video you published a day ago.

I was following the instruction in the README.txt inside semantic_rigidity_cvpr2017. When I tried running python do_deeplab_segmentation.py TEST deeplab_deploy.prototxt deeplab_adam_0.0001_iter_1400.caffemodel . it gives me the following error

FileNotFoundError: [Errno 2] No such file or directory: avg_train_image.npy

Can I use this code to calculate optical flow for a video recorded from a camera fixed on the dashboard of a car?
Also. can I modify the code to calculate the optical flow between 2 images only or this modification will affect the accuracy greatly?

Hi, first thanks for your work ad for sharing it.

I am trying to execute your example but I have the following error message. It seems it may relate to the env variable but I think I did export it properly. Can you help?below the shell outputs when executing:

tets:~/mrflow-master$ sudo python mrflow.py --no_init example/frame1.png example/frame2.png example/frame3.png
Traceback (most recent call last):

    raise KeyError(key)
KeyError: 'MRFLOW_HOME'

Tets

Thank you so much for sharing code.
When I run the demo code:
python mrflow.py --no_init example/frame1.png example/frame2.png example/frame3.png

It raised this error:

mrflow.py:189: RuntimeWarning: invalid value encountered in sqrt
flowdiff = np.sqrt((u-uinit)**2 + (v-vinit)**2)

sqrt returns this error when we square root a negative number. (u-uinit)**2 + (v-vinit)**2 is always possitive, I don't know why it returns the error.
