Here in far west copyright laws make sharing books expensive. Or maybe a few different ones and precessing the files in a few separate batches.Ĭonclusion I guess it's easier to buy a brand new printed or electronic book, if that's available. The needed scripts: No idea, if a single proper filtering exists.

If you are extremely lucky, the whole job takes a week as full day job, probably much more. OCR only partially replaces retyping, it doesn't recreate the pages. Then the whole book must be manually recomposed page by page. All created files must be read and errors must be seen and corrected.

Making them needs manual tinkering page by page. Search for GIMP scripting and Batch processing GIMP. Programmed scripts cannot justify differences in the image content and make cleverly different adjustments, but they can take into the account such things as different pixel dimensions. GIMP doesn't know recorded actions, but a single command can be repeated for all open files. Photoshop allows also scripts which are written in a programming language. In PS one can record the processing of one file and then do the same for all files in a folder automatically. In different programs scripting is different. In this case a programmed script can walk through whole folder of files. no OCR is needed and there exists a filtering where exactly same set of adjustment commands produce acceptable result with every file.

Here's one example: How do I convert images of a page of text to pure Black & White and sharpen the text?ĪDD: Automatic processing with generally available photo editing software is possible if your case is easy one, i.e. Text sharpening and OCR has been discussed in GDSE several times. I bet anything which is only for English with western writing styles are now useless. Make a web search to find which OCR programs can handle your texts. All versions in my hands have been for printed texts. OCR for handwriting is theoretically possible, but I have never seen it. Some OCR programs want grayscale text and you very likely must delete or crop out all non-textual content. Information will easily actually decrease and the text can be more difficult to read.įinding the written content and rewriting can be done manually, but OCR (Optical Character Recognition) programs can greatly help.
Sharpening with GIMP's or other filters generally can make edges sharper (at best), but they also can distort letters.
Too low resolution, compression artefacts and noise are irreversible - nothing can fix them except rewriting. Reversing the causes of the blurriness is a theoretical possibility, very rarely the reasons are exactly known or reversing is found by experimenting. Whatever is the reason, making it sharp again is possible either by reversing the blurring mechanism exactly or by finding what's written and rewriting it saved with high video or photo compression.it's a perfect photo, but the photographed print or handwriting has had hard times.it's a photo with bad lens or noisy image sensor or camera has moved.
