No automatic OCR. OCR needs manual proofing.
k2pdfopt does let you easily crop, make background whiter and sometimes extract text if it's there. If K2PDFopt works for the PDF, then you don't need KOReader.
If the PDF has no decent OCR text layer, then both k2pdfopt or KOReader may be useless for a 6″ screen and larger PDFs from scans.
Most old book & magazine scans are useless even with k2pdfopt or KOReader on even an 8″ ereader, never mind 6″. It can simple or a massive project to convert a PDF to a real reflowable ebook.
