- This step is image dataset creation since you have to detect empty Vs non-empty silo. Capture at-least 1000 images with approximately equal “empty silo” and “non-empty silo” images. Try to capture different scenarios of non-empty cases.
- Use Image labeller to label your images into two said classes. (image labeller)
- This Classification example with mobilenetv2 network can be used with the created dataset to fine tune the network. Alternatively, SVM-based classification can also be tried.
looped start video recording (when there is motion) and stop video recording (when there is no motion) through image acquisition(maybe image processing)

I have an expermiental setup that I want to fully control through MATLAB. I am working on silos. I have a small scale silo which flips with stepper motor and Arduino Uno R3 (pictures attached). I can control stepper motor connected to Arduino through MATLAB (code file attached) to flip the silo (half turn and half turn) now I want to record video with a camera (pic attached).
I want to record whenever my silo is flipped and stop recording when the silo is empty then tell Arduino to flip the silo again and start the video again(this in a loop). Many times the silo clogs and jams. (I have uploaded the video of the setup working and the clogging events for more clarity)
I am stuck at the part on how do I tell if the silos empty or just jammed and how do I use this information to start and stop the recording and flip the silo.
Initially I was thinking that I can use like binary or greyscale values in the vertical direction (to avoid clogging scenario) of outlet region to figure out if silo is empty. But I am still a novice at MATLAB I need help on how to implement these triggers of flipping silo then starting video and checking if silo is empty then stopping the video in a loop.
Any help is appreciated in this issue.

Your problem state confines to creating a binary classifier (2 classes) for empty and non-empty classes based on image data. You can follow these steps to create one:
