Hello.

I have images that contain characters that are made from individual dots, 
like from a dot matrix printer. I tried to use various operations on the 
images (binarization, edge detection, dilatation, ...) and was able to make 
the dots bigger so they are connected 90% of the time. However, detection 
is still very bad.

This image contains characters from A to L

my modified version is

after recognition, Tesseract (3.02, using the .NET wrapper) gives me for 
the standard english language the characters "FJBEDEFEHIJKL". Only the last 
5 characters are right, the rest is wrong. Do you know of a way to make 
recognition better besides training a new font for this special case? 
Tesseract works quite good for other projects I have, I would love a 
solution that does not rely on a special font if possible.
