Handwritten number recognition app

Hi everyone, I would like to build a reinforced learning application using App Designer. This application should look like this:

https://ml.webweb.cloud/digit/draw

I would therefore like to allow the user to draw a number from 0 to 9 and in the training phase indicate what figure it is. Subsequently, in the testing phase, the application will recognize the digit drawn by the user.

Is it possible to do something similar in Matlab? I especially have difficulty realizing the phase in which the user can draw the figure. I found examples of text recognition with images and with the drawfreehand function but I don't get the desired result.

It is important that the app is interactive as it has teaching purposes to introduce machine learning to students.

Thanks to anyone who will try to help me achieve this goal.

Yes, I'm pretty sure there is a simple deep learning example using transfer learning and the NIST numerical image data set. Search for it.

Or you can use HOG features and SVM: https://www.mathworks.com/help/vision/ug/digit-classification-using-hog-features.html

Or ocr See https://www.mathworks.com/help/vision/ref/ocr.html
