How to generate a searchable PDF using some images but executing OCR on their preprocessed version

[Nico]

Hi,

I have a bunch of RGB images I need to OCR and put together in a searchable PDF. I noticed that if I preprocess the images, OCR quality improves dramatically, but those preprocessed images cannot be used the make the PDF.

Is there a way to create the PDF using my original images but execute the OCR on the preprocessed version of them ? 

Thanks in advance

Nico
