FAQ

How can I scan an old dictionary in a way that I can index the content?
There are Book scanning - Wikipedia s machines (which automatically turns the pages and photographs them under good lighting) - and Optical Character Recognition (OCR) programs that will turn the pictures into that aputer can process. However OCR isn 1% perfect - and in situations where spelling and indexing is critical it might not be good enough. I also don know how well they handle accented characters. (See Comparison of optical character recognition software - Wikipedia s ) Once you have the document read in as youre probably going to have to do some processing to get it split up into the key words and the translation and to put it into some kind of searcheable database. It hard to guess what steps would be needed until one sees the output of the OCR program. But those are the technologies youre going to need. Photographing the pages by hand with a normal camera or scanning them on a conventional flatbed scanner won produce the nice even lighting that an OCR program does best with and will result in distorted images due to the curvature of the pages that may cause the OCR software to failpletely.
I have a couple of jpeg / jpg files which I want to compile and store them in a PDF document. Which freeware software should I use?
cover your answer in two situations Situation 1 If you wanna create a customized pdf file in which you have arranged and fixed your files and place them in your desired locations then just save it to pdf format. italic Situation 2 If you wanna just create your pdf with your desired s to specific locations in your pdf then I rmend you to this very nice free conversion service italic Sejda italic ( italic - JPG to PDF italic s ) and upload your image files and convert it. italic So now choice is yours. horizontal-rule I hope this might help you ) Feel free to ask!! Thanks for asking!
Is it possible to hand-write code and then use OCR software to import it into an IDE?
Yes technically you could always have. But the main concern is that humans are much more tolerant to the errors of OCR thanputers are and thus in their current form OCR implementations for language cannot be used as reliably as they are used for code. The most relevant point is that programming languages are written in a much much smaller word set than english. Actually it's usually less than twice as big as the *character set* in english. So you could just train the same algorithm to regress to the words of the programming language instead of english characters and that itself would give you a loooot less errors because there are thousands of english words that have more than a few words only one character from them to get mixed up with whereas java only has 5 that look very different from each other. In fact even if it is a (uniformly) blurry image of print given the definition of the problem it should make the exact same mistakes on every instance of a word because there is almost no variation on a word's input in the picture especially relative to the large dissimilarities between java keywords. I.e. making a mistake get's muuuch harder when don't allow matches to anything but java.

Why are non Chinese not allowed to stay in certain places in Beijing?
I have not stayed in any hotels in Beijing but I have seen this phenomenon (u4edu4f1au5f85u5916u5bbe can receive foreign guests) in Nanjing (where it seems to be verymon) and Fuzhou and on one occasion also in Yangzhou (Jiangsu Province) and Chongwu (Fujian). Generally of course when this issue exists it usually smaller and cheaper hotels which say that they don accept foreign visitors ( and why don you go to a Holiday Inn across the street?) Fortunately I have hardly ever encountered this issue in small cities or towns (u9547). (This is really fortunate as a small town may often have only one hotel and if it does not accept foreigners you have to go to the next town or find a place to camp) Normally it seems a foreign passport (u5916u56fdu4ebau62a4u7167) is an acceptable form of ID for hotel registration as a fairly typical s hotel reception sign (shown below) exs. (All hotel guests in China have to register with an official ID of some kind of course. Unlike some other countries it pretty rare to run into a hotel in China which does not ask for one ID - I suspect that if this happens that because a clerk just wants to keep your cash instead of turning it in to the management or maybe the owner wants to avoid taxes anyhow that not my business. Probably not wise to deal with a business that in violation of regulations). However even when a passport is accepted as an ID the hotel staff often seem to indicate that it a chore to process it. That probably because the standard Chinese ID (u8eabu4efdu8bc1) either a citizen card or a permanent resident ID card is very easy to process - the clerk just scans it in some reader just like the ticket vending machines at train stations or the reception desks at internet cafes (do they still exist?) do; meanwhile to register a guest with a passport a fair deal of typing or writing is required. (This has been recently simplified in some places though it may be sufficient for the reception clerk to simply take a photo of your passport ID page with his or her cell phone. I suppose they have an OCR software to handle the data efficiently). I am guessing that the cities where some hotels don register foreign visitors have official regulations to that effect. The purpose of the regulations presumably is to concentrate all foreign visitors at aparatively small number of places where the registration rules are enforced more stringently and thus reduce the number of cases when people stay without proper registration. Incidentally staying at an AirBNB property is not a problem to stay at an AirBNB property in China one needs to provide one passport information so all the data is fed to the appropriate agency in a centralized fashion. Just as incidentally I wonder how soon other countries will follow China lead at monitoring foreigners movements more closely. (Chinese experience with face recognition systems for example is definitely emulated abroad Will the government get mug shots of all air travelers? s ) The US government for example has already carried out a significant amount of work to set up interfaces whereby airlines ( APIS s ) educational institutions ( SEVIS) s and financial institutions ( FINCEN) s can easily supply the appropriate government agencies with the information about persons (especially of course foreign persons) travel study or banking activities. However a similar interface for landlords and innkeepers seems to be absent so far maybe someone out there is soon to get a juicy contract to set up that as well! (In practice the US or UK law enforcement and national security bodies already have an ability to either bulk-download relevant booking data from major hospitality operators proactively or to subpoena information about specific bookings and stays on as-needed basis just like they can get similar data from telephonepanies but as far as I know there is not yet a mandate for every Mom-and-Pop motel to send booking data electronically to the appropriate agency in more or less real time the way hospitality establishments in China apparently are supposed to do). So far foreigners in the USA merely have to self-register their address changes ( Did you know that most noncitizens must report a change of address with 1 days of moving within the United States? s ) but this obviously does not cover short-term hotel stays.
Obama's long form birth certificate has a text layer. Is this OCR software gone wrong or evidence of forgery?
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
