Hi,
I am looking for a way to merge two separate sources of the same image. I'm trying to cover up a logo on a dvd cover and have a source that shows this part of the image but the rest of the image isn't suitable for use. Cloning is out of the question as the logo covers up too much information for me to re-create it.
Anyway, is there a procedure I could try to match the color levels to make them match closer? They are way off right now and just blindly using the hue and color balance controls is getting me nowhere.
I can post the images if needed.
Thank You.

could this technique be useful ?

EDIT: what ofnuts said

These indeed look like they could help.
Many Thanks!

There is also a script. I cant remember the name that takes a colored image and using a src image layer will modify the colors. I believe it works by taking the color palette from one image and transferring it to another.
I have always opened both images as layers the one i want to change and the src image. Then selected the area i want colored and using hue and saturation get the color close then apply curves to get an almost exact color match.

There is my histogram match script which can have great results depending on the source image.

There is a post here in the forums on it as well somewhere...

Install into your scripts folder go to Filters>Script-Fu>Refresh Scripts.
You can find it at Colors>Map in the GIMP menus.

I have used Pat Davids curve method to match colors, works great.

Well I ended up doing some cloning after all. The sources were different sizes and any color changes to the poor source didn't take well and got blotchy.
That histogram script looks like it would be perfect if the sources were similar, but I got poor results when I tried it after the fact.

The cloning isn't perfect, but the poster was downsized and ended up looking ok. I think I should have descreened it prior to cloning but wasn't about to redo the entire thing again

Good Source with Logo
Bad Source Without
Patch Applied
Cloning Result

Thanks for all the help and suggestions!!

You could make a color pallet of the colors you need to use that are in the other image. Then just use the color pallet you created to get the colors you need. You can also make gradients using this color pallet if needed.
