VietOCR (Java version) does not feed the original image to Tesseract, but rather it reads and then writes back out an uncompressed TIFF file, rescaled to 300 DPI if instructed so, which is then sent to the engine. I found this regurgitated image somehow has been more amenable to Tesseract.
The program also supports a command-line interface that you can use. Glad that it helped. Regards, Quan On Sep 11, 11:46 pm, Jon <[email protected]> wrote: > Never mind.
