    The file 1 appears to have the relevant code for instantiating models. The main chunk of the model is Xception which involves something called “depthwise separable convolutions” (I have not read the paper yet). The output of Xception is then put through a global average pooling layer, then a dropout layer, then a dense layer (i.e. like you would find in a perceptron model), and then a softmax layer.

    With some further reading of the paper, I think the Github repo will have given me a much clearer picture of what the computer vision model

  • This repository provides Python code that identifies plants, birds, and insects in photos.

    This project was inspired by the amazing progress in identifying plants, animals and mushrooms in photos that has been made by iNaturalist in the past years. The iNaturalist team has trained machine learning models with their vast collection of photos and research-grade identifications. In 2019, iNaturalist released Seek by iNaturalist which identifies photos offline on the phone and identifies to a higher level than species when an identification to species cannot be made.

    Google provides three models that have been trained with iNaturalist data - classification models for plants, birds, and insects. These Google models can be downloaded and used with Google's TensorFlow and TensorFlow Lite tools.

    This code is based on the trained models that Google provides. It has been written to experiment with identification of species from photos and to give Seek's approach a try and compute probabilities across the taxonomic hierarchy.

    This tool has been tested on Linux and Windows. It likely works on macOS as well.

    This is a command-line tool. It is called with photos or directories that contain photos and identifies the plants, birds, and insects in these pictures.
    Here is an example. This is the command for Linux and macOS:

    ./ -m plants plant_images/Persicaria_amphibia.jpg
    On Windows the command is:

    python .\ -m plants plant_images\Persicaria_amphibia.jpg
