Remove continuous curved line

Post by evilkid » 2017-10-15T14:33:21-07:00

Hello,

Is it possible to remove a continuous curved line using Image Magick that crosses a text?
however, the line height is always fixed to 2px (and 2 other pixels for shaddow).

Here is a sample text: Image
I have tried: convert capito.png -negate -morphology erode octagon:4 -negate -threshold 70% b.png
and other samples on the net, but none worked.

Thank you.

Most people here will not help to break captchas. Nevertheless, I do not think it would be easy to remove the curved line, especially if it is a randomly placed or randomly shaped curve.

Ok so there is no way to detect a continuous border that is 2px height?
