No box found : Is dhSegment fit for my problem ? about dhsegment

[jlhervy]

Actually I didn't modify the demo script, and when I plot the probability map, I can see that there is some detection of the horizontal lines :

So I will try to play with the post-processing functions that you provide, in order to get the result I would like.

I am still open to suggestions as I feel that this is like big artillery for such a basic task. I am sure there would be a simpler way.
However I have made the lines fat and noticeable for the sake of obtaining a first result, but ideally I would like to detect much thinner lines, sometimes not continuous, and also multiple ones.

Thank you.
