I too got the same error ! The below error is for image, Not sure where is the issue !
CUDA Device: 0 Using image mode Traceback (most recent call last): File "test_background-matting_image.py", line 46, in <module> back_img10=cv2.imread(args.target_back); back_img10=cv2.cvtColor(back_img10,cv2.COLOR_BGR2RGB); cv2.error: OpenCV(3.4.5) /io/opencv/modules/imgproc/src/color.cpp:181: error: (-215:Assertion failed) !_src.empty() in function 'cvtColor'
I faced this error because of the following:
When I use the segmentation model, it needs to create a model by the name "maskDL" and there it stores the segmented image. Hence, it's not able to read the segmented image because it's not there.
Hello, thank you very much for sharing this project, I am having the following error, using video segmentation.
@Flock1 using the online example colab, how do I create a model with the name 'maskDL'?
Using the demo material: #Uncomment and run this if you want to skip uploading your videos (below) and run on the sample videos instead (choose fixed or handheld) It works well
The error I have with my own videos is the following:
CUDA Device: 0
Using video mode
Traceback (most recent call last):
File "test_background-matting_image.py", line 85, in
bg_im0=cv2.imread(os.path.join(data_path, filename.replace('_img','_back'))); bg_im0=cv2.cvtColor(bg_im0,cv2.COLOR_BGR2RGB);
cv2.error: OpenCV(3.4.5) /io/opencv/modules/imgproc/src/color.cpp:181: error: (-215:Assertion failed) !_src.empty() in function 'cvtColor'
Any help is welcome thanks
@tolchx, this error happens because there is no image that is being read. That's happening probably because there is no folder or a file. Kindly check if the required folder or the image is present.

Yes, it was that, thank you very much.
folder and python file paths were in other folders,
Hello, I have an error when I run this section of the code:

I did the test with several videos, with different amount of frames, 600/900/1000 frames, for example.
But it always stops at 441 and the error appears.
What could be the cause?
In the folder: Background-Matting / colab_inputs_video / inputs, the remaining frames appear, it does not end at frame 441
Thank you
@tolchx, I'm not sure but I think there is a problem with arguments. Instead of --tb, just use --back. Also, how are your results? Can you share them with me because I'm not getting that good results. I had to do some post-processing.

I had good results with some videos, I'm experimenting with other material, here I uploaded a video, use the algorithm to segment the dancers, and then apply styletransfer https://www.instagram.com/p/CAsK54qgx_9/
I will try the solution you recommend, thanks
@tolchx, you are using it for something interesting. Can you elaborate on what you are doing? Also, did you make any changes to the code? Because I had to do some post-processing to get good results.
@Flock1 Have you got a good result? Can you share some tips? thanks
and I too got the same error

@zbvictory, as I mentioned here, this error happens because the folder doesn't have the image you want to work with. Do check the folder you're getting the image from.
My raw results weren't that good. I'll share the changes I made.
@Flock1 Thank you very much for your reply and look forward to your sharing !
Hi! I have a small query. I am very interesting in background matting as a technique, however, I don't have photos with a separate background with and without the subject - I have photos of birds in a cage, and I wish to remove the background of the cage bars. I used the background photo for each image as the cropped background of the cage, so the photos are not the same size for the segmentation.
I got this error code
CUDA Device: 0 Using image mode
But it didn't seem like the segmentation actually was performed on the 7 examples of background and image that I provided - any advice would be GREATLY appreciated!
My results when I try and plot are [] instead of any images
@Sicily-F, from what I can imagine this is probably because it's not reading the images. Can you post the whole error? I might be able to figure out where exactly is the problem
This colab is no longer works because tf<2 is no longer supported in google colaboratory.
I'm getting issue when Setting up the environment:
can u please explain how to solve this issue
In general, colab can be quite finicky (I think someone had their file get lost because the runtime restarted); if anyone has issues like these it may help to either (a) run the repository in a more standard environment or (b) add asserts to double check all the files exist and the segmentations + homography transforms don't fail for whatever reason.
