I would like to do a simple program, reading images in the live video from the camera, then do some processing on the image every some time, for example, check differences between images as motion detector, but is it possible to make it with App Inventor?
Welcome
Probably not simple.
- Streaming video is difficult (use the large magnifying glass to search this community). I don't think this is possible to capture a single video frame using Blocks but it might be with an extension.
- code that allows a user to take pictures automatically might be in the community
- you possibly can check the differences between images using the Personal Image Classifier on some Android hardware.
Parts of what you want to do might be possible in my opinion depending on your coding skills.
