## Description

This dataset has been generated by Edge Impulse teams and contains images of vial tubes filled at different levels with a green liquid.

The images in the training set have been captured using 5 different backgrounds. The images in the testing set have been captured using 9 different backgrounds. The `background` information is available in the metadata of the data samples.
