Hiya,

I would like to replicate the following plot:

I have an n x n binary matrix, the ones indicate where the road should be and the 0s where nothing should be. Ignore the red dot.

Thanks!

imshow(~YourData)

to get the 1s to show up dark.

Use edge detection. It will identify the road boundaries.

Thanks for answering my question but with imshow() I get a picture like this

I think the figure is created in another way

Is your concern that the background is showing up in white instead of in light gray ?

Read this link first, then tell us what "replicate" means to you. Like make copies of, like the repmat() function does? We really have no idea what you're thinking.

Couldn't it be possible to create a 3d plot and then you look at it from above - but I don't know how to do this

... We still do not understand what you are asking for, so we cannot advise you if there is a way to do what you want.

There might be, but since we don't know what you want, we don't know what to tell you. We don't know if it's a display/visualization problem, a line detection or segmentation problem, a replication/copying/pasting problem or something else.

It is an ML problem. By using a recurrent ANN a game has to be solved. A game where there is a car (red dot) and you want to minimize the amount the car is not between the road (the two lines). So this picture above is just a snapshot of the game you would plot after each result to see the car moving
