OCR for Android

About OCR for Android Android App

Tesseract was originally designed to recognize English text only. Efforts have been made to modify the engine and its training system to make them able to deal with other languages and UTF-8 characters. Tesseract 3.0 can handle any Unicode characters (coded with UTF-8), but there are limits as to the range of languages that it will be successful with, so please take this section into account before building up.
Tesseract 3.01 added top-to-bottom languages, and Tesseract 3.02 added Hebrew (right-to-left). Tesseract currently handles scripts like Arabic with an auxiliary engine called cube (included in Tesseract 3.0+)
Tesseract is slower with large character set languages (like Chinese), but it seems to work OK.
Tesseract needs to know about different shapes of the same character by having different fonts separated explicitly. This used to be limited to 32 fonts, but the limit has been raised to 64. It is set by the constant MAX_NUM_CONFIGS defined in intproto.h. Note that runtime is heavily dependent on the number of fonts provided, and training more than 32 will result in a significant slow-down.
Any language that has different punctuation and numbers is going to be disadvantaged by some of the hard-coded algorithms that assume ASCII punctuation and digits.

Hence this version is using some of the open source code to build and implemented onto android using source from
