Finding image dataset of color-blindness charts

Question

I had an idea to train a CNN to classify numbers seen on color-blindness charts like the one seen below.

I have Google for such dataset but did not find anything. How should I approach this?

Answer 1

You could start with a benchmark using the MNIST dataset. There are many tutorials and articles written on training a CNN for digit recognition. You might also want to consider preprocessing your color-blindness charts input data (e.g. converting to grayscale, enhancing digit contrast).
