How to remove background from 3D reconstruction

[firststepdev]

Describe the problem When I generate a 3D meshroom model from a series of images outdoors, the background of the image is also captured. I don't need / want the background. How do I generate a 3D reconstruction of only the foreground subject?

Dataset The dataset of images used can be found here (50 images, 50Mb): https://drive.google.com/file/d/1trKK2vzyf2Egg_rKbKniMzCgshcvOUs_

Log The build runs successfully.

Desktop:

• OS: CentOS

Additional context I am running this via Linux command line.

$ Meshroom-2021.1.0/meshroom_batch --input ./frames --output ./output

I am looking for a command line solution.

Try segmentation of original images
