Detecting Letters

it is very complex and the tutorials are not clear

Hi, this is how the process works to train your own CNN: Open MV Cam H7 Plus - Edge Impulse Documentation

We do not offer an out of the box CNN because almost everyone wants to do something different. As such, you should put the effort in to make your own.

hello I want to use this code for detecting A,B,E letters this is a project for my highschool but when I run the code give me an error that mean I don t have nn module
how can I install nn library ?

I also download the trained file from GitHub

Which switched everything to TensorFlow lite for microcontrollers years ago.

There’s no NN module anymore.

how can i detect letters with TensorFlow ?
Does openmv have any trained file for detecting letters ?

Hi, you can train a network via edge impulse for detecting letters if you’d like.

in openmv do we have any ready trained file for detecting letters?

I trained a file in edge impulse with 4200 dataset with 3 class of H,S,U but the code wasn’t such as fast that I want

Hi, no, we don’t.

I demoed this feature once years ago. But, it’s not something we really support. You need to manually collect your own dataset to train a CNN to detect each letter/number.
