Batch removal of pattern from scanned images

Hello all,

First post here, so be kind and explain this like you would to a five year old. I'm starting a new project for my company that is going to require scanning about 600+ pages of photo albums. Usually not a big deal for the auto crop and separate functions of CS6. Here's the wrinkle, all of these photos were mounted on those wonderful late 80's photo mount pages with these lines to affix the photos to the pages. The photos are on loan so removing them from the pages to scan is not an option. We are scanning at 720 DPI, and I need a way to batch remove the lines to get a white background so we can run them through the batch separator. I have CS6 at my disposal and have played around with the FFT filters, etc without much luck. I need something that can recognize and remove the same pattern over and over. I need a jumping off point so we can get things moving. I've attached a sample so you can see what we need to remove. Thanks in advance for the help.

Derek

Try File>Automate>Crop & Straighten Photos

It worked for me on your sample, but the full-sized version might be different.

Doug,

You're right! It does work on the smaller image, but will not on the large version. So Photoshop does recognize what needs to be removed.... Anyone with ideas on how to make it work with larger images?

Thanks,
Derek

Can you attach a full rez segment just showing a photo corner and some of the gray lines? Just a square inch or so should do it while staying under the attach size limit.

Hmm...C&S works for me on that sample. Does it work for you on that sample? If not, do you have access to a newer version of Photoshop? I'm using Photoshop CC 2014. If it does then there are other variables at play.

It does leave a tiny border, presumably from the shadow.

Doug,

The swatch will not work in CS6. It just turns the swatch about 40 degrees and won't crop anything. Sadly, I do not have access to anything higher. Is there a way to make adjustments to this feature?

Since this is for work, it might be worth paying for a month of Photoshop.

If you use dropbox, zip up a couple of different full scan files and PM me the link. I'll run them through the newest version and let you know how it goes.

Re: Batch removal of pattern from scanned images

Doug,

I appreciate the offer and I think you're right about paying for the month of Photoshop. I will finish scanning everything first and then button some up and get them over to you. Might take some time. I have about 300 pages down and about 400 to go. I'll drop you a line when I get ready to start processing all of these.

Thanks,
Derek
