Though it's worth noting that FineScanner uses online OCr and the processing takes much longer, about 40 seconds in my case but it may differ, compared to about 3 seconds of offline OCR of TextGrabber and knfbReader. FineScanner turned out to have the best results, with precision about 98% compared to about 90% of knfbReader.
TextGrabber had precision which I would approximate to 35%, although in better conditions when I scanned a flat, clear and well lit document, the precision was almost 100%, specifically, the only error was in some words near the bottom edge of the document where the higher shot angle is starting to affect the readability. Then I loaded the photo to each of these appss, run OCR on the image and compared the results so that the same image is processed in all the apps.
I took a photo of an opened book with the standard Camera app, that means without any software guidance tools, such as those in knfbReader, nor with any human help. I will also share my small experiment comparing FineScanner Pro, knfbReader and TextGrabber. I would also be grateful if the accessibility of the apps was better, such as proper button labeling and feedback.Īnyway, thank you for your efforts and for making quality OCR software and I wish you the best. TextGrabber, on the other hand, is much faster with its offline OCR, although it lacks text defects correction features available in FineReader.So, there is no app which would take the best from both of these apps. Therefore, I am not able to retrieve the recognized text, even though the same steps worked yesterday, as after several tries to OCR, the text was shown, but not anymore as of now.Īlso, I find online OCr rather slow, taking about 1 minute just for a single page. However, when it does, instead of showing the resulting text, the OCR settings screen is shown again and tapping Done just brings me back to the scanned image screen. The only way to check the progress is to press the OCR button again repeatedly until the alert that text is still being recognized disappears. First, when I press the OCR button, check the settings and press Done, I get no feedback about whether and when the recognition is already done. I am using VoiceOver and I am not able to retrieve the OCR result from a scanned document both in Book and Document mode. I will paste here the feedback email I sent to ABBYY concerning me not being able to retrieve OCR text and about FineScanner's accessibility.
