Manually transcribing a note or receipt is so damn laborious, isn't it? And putting it into a scanner is not something everybody can do, wherever they are. But look here, we have a smartphone! And so it happens you can get away with a lot, by only using a camera and the right software package, such as Notebloc.
Notebloc can crop with a corrected perspective any allegedly flat surface from a photograph. Its detection algorithm is reasonably accurate, but you can also edit the selection further. The result will be cropped and displayed as a rectangle. You may save these cropped images separately or into virtual folders.
Furthermore, you may use Notebloc's OCR function to extract the text and numbers. These are going to be stored next to the picture file and can be retrieved through the sharing service, or if you copy the text body using the Android keyboard. The character recognition system can be set to detect specific languages, but it's ultimately up to you to correct its, sometimes, monumental transcription mistakes.
Notebloc can also convert an image to Black & White, as well as apply two more types of filters, which if you ask me, are not doing very much to increase the quality of the output.
- Automatic cropping
- Visual filters
Notebloc is a handy tool for copying information from receipts or clearly-written notes. I wouldn't base copying at an exam on it though.
