How to extract table cells from a picture containing a table of distorted lines

asked 2018-12-26 10:45:44 -0500

I want to extract all the sub cells from a table for further text recognition, the table picture is taken by a phone camera. If the table lines are straight then I can use the way in to extract the vertical and horizontal lines and then extract each table cells, but what if the table lines are distorted? (like the photo is taken from a phone camera and some lines are curved) How to handle such scenario?

Another case is in some cases the line is not solid enough ("broken" in the middle), how to handle such case as well?
