[Linux-bruxelles] FYI: à propos d'OCR: Fwd: sath.linux at ...: EASY-OCR-4.0 Released

[Luc765]

Bonjour et bonne année....

Pour ma part, j'utilise Ocrfeeder avec Tesseract.

Ocrfeeder permet de créer des zones et de distinguer des images du texte.
A la conversion, les images identifiées sont reproduites à l'emplacement
initialement prévu.

> brightness checker, Immediately after you have completed
>   the settings. Please use the page of the book most typical of the whole
> text.

> 6. Settings wizard is now changed to single window.
>
> 7. Easy-ocr will now appear in the Graphics Menu.
>
> How to use EASY-OCR
>
> One can use easy-ocr in two ways. first one is to scan and produce text
> from the program itself and second one is to produce the text from the
> folder containing image. in order to start scanning using the program,
> please follow the steps given below.
>
>
> Setting the scanner
>
> Go to graphics  menu and enter easy-ocr. Then enter the settings and give
> the values for number of pages to be scanned, Time between repeated
> scanning, resolution, brightness or threshold, scan area, language and
> engine. In order to listen to the values entered press the say button and
> press apply button to save the new settings. if you want to continue with
> the old settings please press continue with existing button.  In the
> settings. All the changes you have made in the settings will be kept until
> further changes are made.
>
>
> Scanning
>
> Now go to easy-ocr menu and select either scan or scan with full auto
> rotation. in the scan mode, the program will ask for the file name. after
> entering the filename select the rotation mode. if you are sure of the
> angle in witch you have kept the book , select the manual mode and check
> the degree of rotation. if you are not sure of the angle, please select the
> automatic mode and scanning will be done in order to determine the rotation
> needed. then the rotation selected will be kept and you have to start from
> the first page itself.be careful not to change the angle kept in the
> beginning. after each scanning, the page number will be announced and after
> hearing one, you can press add button and start reading along with
> scanning. if you are totally unaware of the angle in witch the papers are
> kept, you can select full auto rotation mode. here also after hearing one,
> you can start reading by pressing add button. the text produced by these
> two modes will be saved in documents unless you change the directory. if
> you are in need of continuing the file, you can select the same file and
> the text will be appended to the old one.
> The most preferable mode is the SCAN mode and Scan with full auto rotation
> may be used for bundle of papers which are not knit. Remember that only the
> CUNEIFORM can work with all 24 languages and other engine can handle
> English  After the text has appeared and started reading, you will have to
> press alt plus tab to get back to easy-ocr window.
>
> >From folder
>
> Now one can convert images saved in the folders in to text by using the
> folder option.if you are not in a position to use the easy-ocr, you can use
> any scanning program to produce the images. this option will support png,
> jpeg, jpg, tiff, tif, pnm, pdf formats. select the folder option and enter.
> now you will have to select the folder, format of the image,rotation mode,
> saving folder.etc. if you are sure of the angle in witch the images are
> kept you can select manual mode, and if you are not sure of the angle, you
> can select automatic mode. in the automatic mode, all the images will be
> converted, as in the angle of the first image. in the full auto rotation
> mode, we are not to be concerned of the angles. Be careful to name the
> folder or files inside without a space between the characters If there is
> one, please rename it.
>
> Audio conversion
>
> there is facility for converting text in to wav files. just enter the audio
> conversion mode and select the folder containing the text to be converted
> and give the values in the window shone.
>
> Stop all process
>
> One can stop all scanning process by entering the stop-all-process
>
> Brightness checker.
>
> In order to determine the brightness to be used, please select a page of
> the book to be scanned and enter the brightness checker. there is auto
> rotation facility here. Now the scanning will start and there are 2 phases.
> in the primary level, four  to six scanning will be done and in the second
> stage, ten more . in each stage, the program will announce the number of
> words found at different brightness levels. after the checking, the value
> will be added to the settings automatically.
