I have the textbook for a college class I am taking that is in PDF format with each page of the textbook saved as an image, and I can use pdfimages to convert it to a series of images. Both Tesseract and Cuneiform seem suitable to the task of scanning the images and producing text files, but it would appear they can only do one page at a time. Anyone know a way I can have Tesseract, Cuneiform, or another command line OCR utility scan multiple image files and output the extracted text to a single .txt?
