How to create the binary mask used in the code

---

This post explains the process to create binary_mask which is automated in v1.1

First, a ring_mask is created:

Then it is unwarped:

To create the binary mask, the position of the first column and first row that a Vec3b(0,0,0) appears are recorded and used accordingly. A potentially better method is to create the binary masked by a graphcut-based seam finder (not implemented in this repo).

Hope this is helpful.
