Betreff: RE: Text inserted by camara


Hello, you need to apply some special filters to remove the background and
the text outline and to keep the text only (the white color on the picture).

After that you need to train Tesseract for exactly this font (same font
name, same size, same color, same character spacing, etc. It is important to
compile a comprehensive dictionary (if possible). This process will improve
the results but 100% accuracy is unlikely to be achieved (with Tesseract).

Note that Tesseract is designed for 300 DPI images with font size of 8pt -
64pt and when the image has less DPI (even when the quality is perfect) or
the font is relatively smaller it does not perform well (* this conclusion
is unofficial, just my personal experience).
