- [Image source iterators yielding single Frame](https://github.com/landing-ai/landingai-python/pull/125)
Migration Guide
Whenever you iterate over an image source (`NetworkedCamera`, `Webcam`, etc), each iteration yields a single `Frame`, and not a `FrameSet`.
But most `FrameSet` operations were migrated to `Frame` class, so you can still use the same API to manipulate the `Frame` object with very minor changes:
1. On `for frame in image_source:`, don't use `frame.frames[0]` anymore. Instead, you should just use the `frame` object directly (to do resize, check predictions, overlay predictions, etc).
2. `Frame.save_image` receives a direct file path to where the frame image should be saved (not just a prefix, as it happens with `FrameSet`).
