Plant Health Classification with ViT

""" description = """ This Plant Health classifier app was built to detect the health of plants using images of leaves by fine-tuning a Vision Transformer (ViT) [google/vit-base-patch16-224](https://huggingface.co/google/vit-base-patch16-224) on the [Beans](https://huggingface.co/datasets/beans) dataset. The finetuned model has an accuracy of 98.4% on the test (unseen) dataset and 100% on the validation dataset. How to use the app: - Upload an image via 3 options, uploading the image from local device, using a URL (image from the web) or a webcam - The app will take a few seconds to generate a prediction with the following labels: - *angular_leaf_spot* - *bean_rust* - *healthy* - Feel free to click the image examples as well.
