Tesseract is an open source OCR engine that gives fairly good results. It's my understanding that Google use it for Google Books. OCRFeeder is a project for document layout analysis that works as a nice GUI for Tesseract.
Ocropus is another known open source OCR system.
At least the following are supposed to work, although I haven't verified them:
;debugOn // verbose logging
;debugOff // non-verbose logging
~usbNetwork // starts a Dropbear SSH server
;ReadingTimeOff - switches off the reading time display
;ReadingTimeOn - switches on the reading time display
;ReadingTimeReset - resets the reading time computation
ABBY Finereader to a text file
proofread text file against images
use NoteTab Pro to HTMLize the text
create ePub structure in Oxygen, cut and paste HTML into ePub files
view with Calibre and Adobe Digital Editions
check with ePub Validator (http://validator.idpf.org/)
If you don't proofread, you're going to get scannos (equivalent of a typo, resulting from ...
For commercial software you could try ABBYY FineReader or alternatives, or Omnipage or alternatives.
Both can output in Searchable PDF format, which is useful because if you use OCR on books you will never get 100% the right content without proofreading.
Scan Tailor is software that helps optimize the images resulted from scan of books and it is free.
Its features include:
Split pages (very useful when you scan two pages at once and want to make a single page view ebook)
Select content (can be used to remove the pagination and any other content that do not make sense in flowable ...
In my opinion the relative inaccessibility of DjVu's libdjvu, including having their own bytestream compression contributed to the low acceptance of the DjVu format over the years and not patent issues. This hinders other software developers adapting their software to support DjVu and even more so
when porting to a new platform.
The DjVuLibre software has ...
Some options are:
There is Kindle Collection Manager (I didn't try that.) Here are some instructions. And here you can find the developer.
Calibre also has a Kindle Collection manager plugin, here is a howto, a semi-official forum.
The point of failure in all these toolchains is the OCR.
It is well worth the time spent tracking down clean, undamaged,
unfaded, non-yellowed copies with a good-quality print impression,
if this is at all possible.
If you can, get a local craft bookbinder to trim the spine off the
book with a power guillotine, and then use an autofeed scanner on
Scanned texts are most efficiently stored in the DJVU format, if lossy compression is acceptable (if not, use a multi-page format like TIFF).
If you convert scans to the DJVU format with OCR recognition enabled, you can extract the OCR-ed text and use if for EPUB generation.
On Linux you can do so using djvutxt to get the text and convert that to EPUB.
Your question -- if I may restate -- is whether there are tools which allow you to create ebooks natively for Kindle.
Probably not, although it does have some specialized creation tools (Kindle Textbook Creator, > Kindle Kids' Book Creator, Kindle Comic Creator, Kindle Previewer).
My guess is that only Amazon.com could create such a tool because the ....
Aldiko, though not perfect, is by far the best ebook reader available for Android. It has full support for all ePub features, plus PDF, and has a reasonably nice UI unlike all the other apps.
It has all the features you asked for, except built-in ColorDict support - however, you can "share" selected text using the Android sharing system, which allows you to ...
Here is a project that handles every step of the process.
There is an open source project called Homer that installs a suite of software to help with this including ScanTailor and tesseract-ocr. The final result is a searchable PDF. You can copy the text layer from the pdf (or the related html file created in the process) and paste it into an editor like ...
Ed, the answer more depends on your purpose. The literal answer is Scrivener does indeed create valid e-books and is well maintained. I've used Scrivener for Mac for years. I've occasionally compiled the document to kindle format to carry around. That process works just fine.
If your real purpose is to Write the Great Novel or some other large and complex ...
They are almost certainly done in TeX/LaTeX. TeX/LaTeX is not about "less effort", but exactness. It is a programming language for typesetting with a special emphasis on math and equations. TeX has a long history with the academic community in publishing. Explaining TeX and LaTeX is outside the scope of this forum (There is a TeX.stackexchange.com site). You ...

You can use Firefox with the EPUBReader extension.
With the extension installed, open Firefox, then Ctrl+O to open a file. Locate and select your epub file.
By default, EPUBReader shows the ebook paginated. To get continuous scrolling, go to Settings (bottom left of the screen) and select Reading Styles > Website.
(Note: EPUBReader does not open ebooks ...
I was impatient so I went ahead with the procedure. (Although worried about bricking a new device, I got it mainly to read PDFs and therefore really wanted to have KOReader up and running).
So I will sum up here the procedure for first-time installation of KOReader on fresh new Kobo Aura ONE.
Note that this is just the procedure that I followed, it might ...
For general purposes, Ebooks are simple websites, contained inside of a predictable folder. This folder is composed mostly of the content of the ebook itself which is the form xhtml and css. The other files are files which declare exactly what contents are in the ebook folder. Each xhtml page, stylesheet, image, font, etc. is listed in one of these files ...
There are several screen readers available, these are high end products used by totally blind and visually impaired user to operator a computer. JAWS is preferred by all the blind computer users I know. According to this there is a version designed specifically for tablets.
Be aware, the creators of PDF documents, often do so without consideration for ...
The commands ~ds and ;411 worked for my kindle paperwhite 3. The ;411 command even measures the temperature of the display! To re-enable screensaver for ~ds command, you must reboot the kindle paperwhite a few times. Mine took two times.
I doubt if that particular one was done in LaTeX's native "picture" environment, but it might have been done with TikZ running inside LaTeX.
Any vector graphics package can produce this kind of diagram: an excellent open-source one is InkScape, but Libre Office Draw is also good. Both can save a PDF vector image, which can then be cropped and combined with ...
Git can be used, but if you use with epub, or any other kind of archive files then you will not get a meaningful diff between versions, just store each version of the ebook. You can use Git wit literally everything, but if it is not like a simple text file, the diff will fail.
Also, you can set Git LFS for such kind of files as ebooks, it has the advantage ...
I've done it by converting each PDF to Word, for which there are a bunch of free converters online. Then I use Word's file comparison feature to see the differences: http://support.microsoft.com/kb/306484
I have tried many programs but all of them are still in the experimental stage.
Note that at this moment (Oct 2015) NO PROGRAM has support for Kindle v5.6 +. I contacted developers of KDEasy and they quickly answered:
So far we don't see any possibility to support 5.6, Amazon blocked all
the solutions. Sorry for that. Regards, KDeasy Product Manager ...
I don't know exactly what you need but you can use libreoffice with the writer2epub extension that create automatically the epub version and, in conjunction with kindlegen, can create the mobi version
or you can give a try a Jutoh (http://www.anthemion.co.uk/), a book creation software that generate epub and mobi
hope this can help
