I am brand new to MIT App Inventor (no real programming background/self taught) and also trying to teach myself Korean. I was inspired to create an app to display a hangul consonant vowel pair, let the user trace it, and then let the user know if they traced it correctly.
I made images with a light grey text of each of the hangul letter pairs and uploaded them as media. I used canvas to display the image as a background and was successful in coding tracing the letters.
I was able to make training data and uploaded the mdl file for the personal image classifier .
Where I am stuck is saving the canvas image and then classifying the saved image. I’m not sure how to properly use the blocks for this, or if I am using the right tools.
Can canvas user drawings be saved directly to where the Personal Image Classifier can use it? If a canvas drawing is saved to device storage, can it be deleted after it is classified? I see how the File component allows for deletions, but does canvas save to where the file component can delete it?
Any assistance would be much appreciated. All examples I have tried to look at use the camera for classification and not canvas.
Much thanks!
