Generated marker border artifacts

[MickaMickaMicka]

Hi,

thank you for the great work!

I have seen that there are some makers generated without a white border but with some artifact in the bottom right corner.
Is that a known bug or some intended feature, or some mistake by the user?

Info: I have changed the dictionary to generate 4x4 markers.

Here is a sample cropped image. The artifact is the gray blob on the bottom right. It looks like it is always there when there is no white border around the aruco marker.

Generation of a white border is activated.

Hi!

First, sorry for the late answer.

As far as we know, no, that is not a bug we have found in any of our generations. The code is intended to work with the provided 6x6 dictionary; it should be trivial to adapt it to 4x4 as you have done, but without looking at your specific changes I can't really provide any insight into what can be wrong.

Have you found the error in the meanwhile?
