I finally did it! I'm so happy 😀

I trained a simple convolutional neural network, and put it on OpenCV mobile! The neural network is very simple, with only 3 convolutional layers, it has less than 500 parameters. It takes 16x16 images. I trained the network using PyTorch. The architecture is like this: conv2d, relu, maxpool, conv2d, relu, maxpool, and conv2d.

I also only has 10 training data (1 for each number), so to add some randomization, I used torchvision to augment new data. I think the random perspective is really good.
