I'm looking for software that searches through multiple images or a PDF for an smaller image that I give it.
The best example I can give is with this page from a stamp catalogue:
I would give the software a scanned stamp image, and it will find (all) candidates.
I know this is not easy, and a lot depends on image size and quality. Assume good quality scans/PDF and pictures of approx. equal size (again, looking for a stamp in a professional catalogue is a good example).
- Free is always nice ;-)
- Input image type can be anything common (BMP, JPG, PNG)
- I would prefer searching though a (multiple page) PDF, but I can convert the PDF to images for each page if need be. Then the tool should check against a folder full of images.
