I have an android application where I am using Tesseract OCR i.e the TessBaseAPI. This requires tessdata which is 21mb file. My final app release APK comes to approx 19 mb which I find quite a lot. Is there any way by which I can reduce the size of tessdata or my app or anything else which will help me reduce the final APK size?

You can use the 3.01 version of .trainddata files -- they have much smaller size -- which are still compatible with newer versions of Tesseract.

  • I found negligible difference in my samples, but you certainly can test for more definitive comparisons. – nguyenq Jan 02 '16 at 16:44
