Docs Matter is a good document mobile scanner for you. I am also using it to scan my paper documents and retrieve s from them. Besides I can edit the recognition results and save them. Wherever I am I can search for the documents I need with entering few keywords. It can convert documents into PDF Word Text format files. It also have PC version. Yunmai Document Recognition is really great for me. When choosing OCR software I always think about the recognition accuracy and recognition speed. The average time for recognition of a document less than 6 seconds. The recognition accuracy can reach 99%. I think you can go Docs Matter - Mobile Scanner - Yunmai Technology and to have a try. You can alsopare it to another scanners. There are lots of mobile scanners on Google Play.

I just tried on the Kindle Cloud Reader and was not able to copy no matter how I tried. However when I tried to open the same book using Kindle for PC I was able to copy and paste . You can download Kindle for PC here Amazon Kindle for PC Install Instructions If the book you're reading is only an azw3 format book and you can't open that with Kindle for PC you can try using Calibre to convert it to another format such as txt or html calibre - E-book management When looking up the s for this I learned that some people had trouble converting awz3 format using Calibre but simply changing the file extension to awz allowed them to fix that problem. It's worth a try. )

I found an answern What plausible is that somewhere along the way from the scanning device to the PDF-creation software italic both of which can perform OCR (optical character recognition) these partial converting it to a PDF optimizing that PDF and then opening it up in Illustrator does in fact create layers similar to what is seen in the birth certificate PDF. You can try it yourself at home. n n UPDATE II For those of you who still aren convinced here italic a one-page PDF that I just scanned and optimized so you can see for yourself that an optimized PDF shows up in Illustrator as layers. (I didn spend hours getting the settings right.) n-Nathan Goulding National Review

The OCR feature is super-cool and surprisingly good -- it actually was able to recognize most of the characters in a (neatly u6977u4e66) calligraphed reprint of one of the early u7ea2u697cu68a6 manuscripts -- but if you've got enough Chinese to be familiar with radicals and stroke order or if you've got Apple's basic handwriting input system and don't mind spending the one second it takes to draw stuff in yourself then it's really not crucial. Which Pleco add-ons are or aren't crucial sort of depends on where you are in your study of Chinese. If you're able to use Chinese-Chinese dictionaries the u6c49u8bedu89c4u833u8bcdu5178 is worth the price of purchase; if you prefer Chinese-English dictionaries but need something with more oomph than the built-in dictionary the ABC Chinese-English dictionary is great for general use though it's missing a lot of newer vocabulary. Supposedly Pleco will be releasing a new pack of dictionaries at some point this year and I'm looking forward to that; ABC and the Guifan dictionary are the only real must-haves from the current set of options I think. OCR is super-neat but I don't think I've ever actually used it in anger -- though then again I'm a translator rather than an active student of Chinese so my use cases may be different from yours. I will say that the handwriting input add-on for Pleco which licenses handwriting recognition tech from Hanwang is awesome and totally worth the price of admission if handwritten input is something you do with any regularity. It's absolutely miles better than Apple's though supposedly iOS 6 will feature improvements to Chinese input and is more forgiving of cursive input nonstandard stroke order and all the real-world issues that Apple's system tends to fall down on.

Artificial intelligence is being incorporated into OCR s toe up with a flexible and reliable automated process. The working mechanism of such systems is based on three major stages and requires no manual interference. 1. Pre-Processing For successful character recognition the to binary s for the sake of simplicity. It also influences the recognition quality to a significant extent for making careful decisions on the provided input. Layout Analysis and Line Removal It identifies the columns paragraphs and distinct blocks filtering out non-glyph boxes and lines particularly in the case of tables or multicolumn layouts. This aspect of pre-processing enables OCR technology to identify and data written in the form of columns so that the data extraction is thorough and no is left un-scanned. Script Recognition In multilingual documents the scripts may change at the level of words which makes the identification of scripts necessary before the character recognition process. It helps in enhancing the data extraction as the appropriate OCR parameters can be invoked for the specific script. Character Isolation Multiple charactersbined due to on the grid. Due to the uniformity of the white spaces between characters vertical lines least intersect black areas of characters. However for proportional fonts the more advanced approach is required because of the presence of irregular white spaces. 2. Character Recognition Character Recognition works in two ways Pattern Recognition Pattern Recognition works on the Matrix Matching algorithm whichpares the image to a stored glyph pixel-by-pixel. It relies on the correct isolation of the input glyph stored accurately as per a similar font and scale. This technique works flawlessly for the written document in the same font. Feature Extraction Pattern recognition can be ambiguous in the case of multilingual documents. Instead of identifying the character as a whole feature extraction identifies the individualponents of a particular character by dposing it into features e.g. lines line intersections closed loops line directions etc. These features are thenpared with the abstract vector-like representation of the character which makes the entire character recognition processputationally efficient. This wholeparison process is done using the k-nearest neighbor algorithm which decides the nearest match. For example the alphabet A has three individualponents; 2 diagonal lines and 1 horizontal line _ 3. Automated Form Population Form populate can be seen as an automated data entry process. The stored data in the memory from Pre-processing and Recognition steps is populated in the requisite fields of the verification form; saving the time of end-user. To increase the OCR accuracy for the document the output is constrained to some post-processing techniques. Near neighbor analysis is one such technique which uses the concept of co-occurrence frequencies to correct errors and identify certain words that should be written together. For example Washington DOC is always written as Washington D.C.

It is quite easy to do OCR on a scanned file or open with Google Docs the OCR will be performed automatically then download the file as Text or any other supported format. Even there are great professional programs s getting you the most accurate results and retaining the formatting also provide amazing user experience with extended features such asimport information from scanned business card into database programs(contacts mailairdropetc)
