Android Question How to read segment display?

[rtek1000]

Hello,

I would like to read the display of my digital multimeter,

I found an App "Yomzo" that uses "OpenCV Manager", does anyone know how to read segment display?

The App:

The OpenCV Manager:

Wow! This app is really cool, I tried with displays found in Google Images and a good part was recognized, but the point is more difficult to achieve,

I found this another great job for Python and iOS:
