Android simple gesture recognition?

Question

Java

For the test task, you need to write a program for Android, recognizing simple gestures. There are 2 areas of the screen, one shows the photographed gesture of the palm from the camera or gallery, the second area shows the recognized symbol. for example, the alphabet of the deaf and dumb.
Please help with literature on this issue. Where can I read about recognition, how to implement it on Android, etc.

Answer 1

This will probably help you (and indeed the entire OpenCV help):
opencv.org/platforms/android.html
There is an object detection section, there are good examples. I wrote something similar (logo recognition) only under Win, I did it in 2-3 days in the required quality, it could have been done better, but I would have had to dive into computer vision much more seriously, there was no time.
Here is my question, maybe it will also make your work easier:
