Many users like the OCR quality of our OCR Engine2 for Western character sets/languages.
With our new OCR Engine5 we bring the same high OCR quality to non-latin characters languages. It starts with support for Chinese. Simplified characters (as used in China) and traditional characters (as used in Taiwan, Hongkong and Singapore) are both supported.
Engine5 can handle text on complex backgrounds, low contrast, uneven light or if it’s distorted well. As an unintended side effect of these improvements, we noticed that the new OCR Engine can also read simple captchas quite good.
So if you have a text that can not be read well by OCR Engine1 or 2, try it with OCR Engine5. But the same goes the other way around, too. Engine5 is not always better. There are documents where Engine1 or 2 give you better OCR results.
