Eikazo 0.5

Eikazo is a GTK and Python based frontend for Sane.
Main features:
- To maximize throughput, a new scan is started immediately after a former scan has been finished, if an automatic document feeder is used. Postprocessing and saving of the old scan is done, while the new scan is running.
- more than one output per scan is possible: You can simultaneously save the scanned image into a file and send it to a printer.
- plugin mechanisms for special devices features, for post-scan image processing and for other "storage options".
The device plugin mechanism allows to implement functions to support special device features.
Image enhancement plugins allow to automatically post-process the image. Currently, three plugins exist:
adaptive threshold
"dirt removal"
ImageMagick
The combination of adaptive threshold and dirt removal can give better scan results for "problematic" originals, for example, if you want to extract the text from a paper with "shaded background", from an stained original, or if you cant reliably predict the density of the ink of the text. See the sample images samples/1.tif (simple fixed threshold, set in the scanner), samples/2.tif ("automatic threshold" from another scanner), samples/3.tif (grayscale scan) and samples/4.tif (adaptive threshold).
The ImageMagick plugin is probably not very useful in many cases; some of the provided options are procesed very slow -- in other words: it is mostly intended to show how to integrate an external image filter than to be directly useful.
