Read the negative reviews and learn from them.
I gave DocScanner a try for its much touted "Curvature correction" feature, which I found out did not exist after purchasing DocScanner from the Apple App Store. In short, DocScanner is vapourware as far as its main selling point is concerned.
The image correction features are a primitive guessing game that provide no live preview of the effects of corrections applied to the image.
The OCR feature is delicate; it works on perfectly framed and lit images in ideal circumstances. In the real world, the best results are achieved when first correcting input files with Prizmo. This is no surprise since DocScanner recycles the hand-me-down Tesseract OCR component built by HP in 1985 and then inherited by UNLV and later Google.
The Help feature and documentation do not exist. "Help isn't available for DocScanner." DocScanner does not even respect (or may not be aware of) user preferences with respect to launching the default e-mail client, choosing Mail.app instead.
I will not purchase any more apps from Norfello Oy unless this situation is remedied with haste. I will also not obtain any more apps from the Apple App Store unless their quality control process improves to prevent such low quality products from reaching consumers. Enabling this product to be available for purchase reflects poorly on both the authors at Norfello, and the reviewers at Apple.
Two questions (sorry for commenting on an older post). 1) has any of this been remedied-especially the curvature correction? 2) You mentioned Prizmo, the other OCR program I am considering. How is the OCR in Prizmo? I am trying a demo version and it appears to be a little picky depending on the image quality/how you adjust it.

ReplyDelete1) I've not tried updated versions of either program since May. Old Prizmo works well enough, but I may do some comparisons of updated versions in the next few days against the pile of page images on my camera.
2) Prizmo's OCR is acceptable if files are well homogenized and binarized. Both tasks are CPU hogs so I find it faster to simply find even (not necessarily good) lighting when snapping photos of the pages. I also leave many files un-OCRed until I need them to be text-workable, in which case Acrobat does a stellar job.
