Re: remove distorted vertical and horizontal line segments

Thank you.
But the implementation looks specific to the image that I shared. I tried the method on another image with little impact of LineRemoval method.

Re: remove distorted vertical and horizontal line segments

Ok. Where can I post the image samples? This forum does not allow it. Also, is it fine if I provide a portion of the image/s? Also, the key issue of image processing in my case is that it should be a generic solution and not specific to one instance. Thanks for responding.
