## Annotation notes

For each image, the annotation was recorded in 'note' section of the corresponding JSON file in the following order:
Stomatal morphology - Sampling method - Microscopy type - Image quality (High, Medium, Low) - Image scale bar (pixels / micrometer). For instance: 'Paracytic_Leaf_Topometry_LQ_2.6'
