Japanese OCR And Dictionary

This is a very basic OCR and dictionary for the Japanese language, that allows quick text extraction from a screenshot or screen region, and lookup of word meanings and usage.

This is a very bare-bones project meant for personal use. I still haven't nailed down the text extraction and splitting. As such, the app is not very reliable.
