1.1 Early historical notes

For some years now we have tested and used OCR softwares, mainly for old books. Popular OCR softwares (those bundled with scanners) are useful tools. However, OCR is not a simple task. The results obtained using those programs vary largely depending on the the printed document, and, for most texts we're interested on, the results are really poor or even unusable. In fact, it's not a surprise that many digitalization projects prefer not to use OCR, but typists only.

For a programmer, it is somewhat intuitive that OCR could achieve good results even from low quality texts, when an add-hoc approach is used, focusing one specific book (for instance). Within this approach, OCR becomes a matter of finding one software adequate for the texts you're trying to OCR, or perhaps develop a new one. So a free and easy to customize OCR (on the source code level) would be a valuable resource for text digitalization projects.

Dealing with graphics is not among our main occupations, but after analysing many scanned materials, we began to write some simple and specialized recognition tools. More recently (in the third quarter of 1999) a simple X interface linked to a naive bitmap comparison heuristic was written. From that prototype, Clara OCR evolved. Since then, many new ideas from various persons helped to make it better.

1.2 Design notes

It's not a bad idea to enumerate some principles that have driven Clara OCR development. They'll make easier to understand the features and limitations of the software (these principles may change along time).

1. Clara is an OCR for printed texts, not for handwritten texts.

2. Clara was not designed to be used to OCR one or two single pages, but to OCR a large number of documents with the same graphic characteristics (font, size, etc). So it can take advantage of a fine (and perhaps expensive) training. This will be tipically the case when OCRing an entire book.

3. We chose not support directly multiple graphic formats, but only Jeff Poskanzer's raw PBM and PGM. Non-PBM/PGM files will be read through filters.

4. Clara OCR wants to be a tool that makes viable the sum and reuse of human revision effort. Because of this, on the OCR model implemented by Clara, training and revision are one same thing. The revision is a sum of punctual and independent acts and alternates with reprocessing steps along a refinement process.

5. The Clara GUI was implemented and behaves like a minimalistic HTML viewer. This is just an easy and standard way to implement a forms interface.

6. We have tried to make the source code portable across platforms that support the C library and the Xlib. Clara has no special provision to be ported to environments that do not support the Xlib. We avoided to use a higher level graphic environment like Motif, GTK or Qt, but we do not discourage initiatives to add code to Clara OCR adapt or adapt better to these or other graphic environments.

7. We generally try to make the code efficient in terms of RAM usage. CPU and disk usage (for session files) are less prioritary.

1.3 Supported Alphabets

Clara OCR focuses the Latin Alphabet ("a", "b", "c", ...), used by most European languages, and the decimal digits ("0", "1", "2", ...), but we're trying to support as many alphabets as possible.

To say that Clara OCR supports a given alphabet means that Clara OCR

(a) is able to be trained from the keyboard for the symbols of that alphabet, eventually applying some transliteration from that alphabet to latin. For instance, when OCRing a greek text, if the user presses the latin "a" key (assuming that the keyboard has latin labels), Clara is expected to train the current symbol as "alpha".

(b) knows the vertical alignment of each letter of that alphabet, for instance, knows that the bottom of an "e" is aligned at the baseline;

(c) knows which letters accept or require which signs (accents and others, like the dot found on "i" and "j");

(d) contains code to help avoiding common mistakes, like recognizing "e" as "c", "l" as "1", etc.

To say that Clara OCR supports a given alphabet does not necessarily mean that Clara OCR

(a) knows some particular encoding (ISO-8859-X, Unicode, etc) for that alphabet;

(b) contains or is able to use fonts for that alphabet to display the OCR output on the PAGE (OUTPUT) window.

Even ignoring the standard encondings for one given alphabet (e.g. ISO-LATIN-7 for Greek), Clara eventually will be able to produce output using TeX macros, like {\Alpha}.

1.4 Clara vs the others

Clara differs from other OCR softwares in various aspects:

1. Most known OCRs are non-free and Clara is free. Clara focus the X Windows System. Clara offers batch processing, a web interface and supports cooperative revision effort.

2. Most OCR softwares focus omnifont technology disregarding training. Clara does not implement omnifont techniques and concentrate on building specialized fonts (some day in the future, however, maybe we'll try classification techniques that do not require training).

3. Most OCR softwares make the revision of the recognized text a process totally separated from the recognition. Clara pragmatically joins the two processes, and makes training and revision one same thing. In fact, the OCR model implemented by Clara is an interactive effort where the usage of the heuristics alternates with revision and visual fine-tuning of the OCR, guided by the user experience and feeling.

4. Clara allows to enter the transliteration of each pattern using an interface that displays a graphic cursor directly over the image of the scanned page, and builds and maintains a mapping between graphic symbols and their transliterations on the OCR output. This is a potentially useful mechanism for documentation systems, and a valuable tool for typists and reviewers. In fact, Clara OCR may be seen as a productivity tool for typists, instead of a typical OCR.

5. Most OCR softwares are integrated to scanning tools offerring to the user an unified interface to execute all steps from scanning to recognition. Clara does not offer one such integrated interface, so you need a separate software (e.g. SANE) to perform scanning.

6. Most OCR softwares expect the input to be a graphic file encoded in tiff or other formats. Clara supports only raw PBM/PGM.

1.5 The requirements

Clara OCR will run on a PC (386, 486 or Pentium) with GNU/Linux and Xwindows. Clara OCR will hopefully compile and run on a PC with any unix-like operating system and Xwindows. Currently Clara OCR won't run on big-endian CPUs (e.g. Sparc) nor on systems lacking X windows support (e.g. MS-Windows). Higher-level libraries like Motif, GTK or Qt are not required.

A relatively fast CPU is recommended (300MHz or more). Memory usage depends on the documents, and may range from some few megabytes to various tenths os megabytes The normal operation will create session files on your hard disk, so some megabytes of free disk space are required (a large project may require plents of gigabytes). Clara OCR can read and write gzipped files (see the -z command-line switch).

If you need to build the executable and/or the documentation, then an ANSI C compiler (with some GNU extensions) and a (version 5) perl interpreter are required.

1.6 How to download and compile Clara

For those who need to download and compile the source code (hopefully this will be unnecessary for most users as soon as Clara binary distributions become available), it may be downloaded from http://www.claraocr.org/. It's a compressed tar archive with a name like clara-x.y.tar.gz (x.y is the version number).

The compilation will generally require no more than issue the following commands on the shell prompt:

$ gunzip clara-x.y.tar.gz $ tar xvf clara-x.y.tar $ cd clara-x.y $ make $ make doc

Now you can copy the executable (the file "clara") to some directory of binaries (like /usr/local/bin), and the man page (file "clara.1") to some directory of man pages (like /usr/local/man/man1). By now there is no "make install" to perform these copies automatically.

If some of these steps fail, please try to obtain assistance from your local experts. They will solve most simple problems concerning wrong paths or compiler options. You can also read the subsection "Compilation and startup pitfalls".

1.7 Compilation and startup pitfalls

This subsection is intended to help people that are experiencing fatal errors when building the executable or when starting it. After each error message we'll point out some hints.

Bear in mind that most hints given below are very elementary concerning Unix-like systems. If you have problems, try to read all hints because details explained once are not repeated. If you cannot understand them, please try to ask your local experts, or try to read an introductory book on Unix things. Please don't email questions like these to the Clara developers, except when the hint suggests it.

1. Path-related pitfalls

$ make bash: make: command not found

The shell could not find the "make" utility. Maybe there is no such utility installed on your system, or maybe the path to it is unknown to the shell. You can try to find the "make" utility with a command like

$ find /usr -name make -print

The following command will display the current path:

$ echo $PATH

Remember that on Unix-like systems the environment is per-process. So if you change the PATH variable on the shell prompt within an xterm, this won't affect the other running shells (on the other xterms). Remember that the Unix shells expect to be explicitly informed about which variables must be exported to subprocesses (use "export" in Bourne-like shells and "setenv" on C-like shells).

$ make gcc -I/usr/X11R6/include -g -c gui.c -o gui.o make: gcc: Command not found make: *** [gui.o] Error 127

The make utility could not find the gcc compiler. Check if gcc is installed. If not, check if some other C compiler is installed (for instance, "cc"), and edit the makefile to chage the value of the CC variable.

If you don't know what I'm speaking about, take a look on the directory where the Clara source codes are, and you'll see there a file named "makefile". This file contains the names of the tools to be used and rules to build the Clara executable. It contains also important paths, like those where the system headers (files .h) and libraries can be found. If the names or the paths don't reflect th"makefile".
