image text sharpener

Stage 1. Finds text areas and marks them (say, with a yellow "marker")

Stage 2. Finds drawing/picture areas and marks them differently (say with a half-transparent light-purple box)

Stage 3. Allow user to change sensitivity of automatic text- area discovery (which would change for example how much of the text that's seen from the other side of the page is to be detected, or stuff written in pencil).

Stage 4. Allow user to "mark" more text to be treated, and to "unmark" part of the texts that was previously marked, so those areas will not be treated.

Stage 5. The user can choose to sharpen with or without OCR.

Stage 6. When sharpening with OCR, the letters are retrieved. Questionable letters give options of which letters they could be. For example capital O Q C or D

Stage 7. The user can choose colors for treated background and text.

Stage 8. The user can choose to treat the background or leave the background as is.

Stage 9. Press sharpen,

For the default all areas outside the two types of markings are turned to white and the texts are sharp.
