I have an image but on the top of the image there just isn't enough room to make it applicable for my desired application. Therefore I would like to extend the pattern that is clearly visible in the background. The pattern and image are the following:


I tried using the content aware filter and this gives me the following result:

Content Aware

It just doesn't know how to handle the cross part. So I also tried the clone tool, and this looks good but looks like aliasing has occurred when looking from a greater distance:

What to do to straighten the lines in the last image out or redo it completely in order to get a nice extended pattern?

  • I noticed that the line distance seems to vary a bit, which makes copying the lines a pain in the ass.

    If possible, I'd remove the background and rebuild it from scratch. Your original image show wavy, uneven lines -- that can only really be corrected via reconstruction.

As Scott says, you'd probably be better off removing the background and replicating it. It looks as though you could create and use a pattern which would save you some time. That way would avoid all the extraneous artifacts and you could apply any other filter with ease.
