MEWC - Mega Efficient Wildlife Classifier

Introduction

This code repository contains example scripts for camera trap animal detection and classification. Our container based approach to camera trap image processing is modular, easily scalable, fast to deploy and lowers system prerequisites. Developed by RZA, JCB and BWB.

Quick Start Vignette

We have provided a Quick Start Vignette that will guide you through the process of pulling necessary Docker images, training an EfficientNetV2 model using 10 species of Tasmanian animals and then using the trained model for inference to classify camera trap images from an example camera service. The entire process can be completed in an afternoon ona a NVIDIA A100 Cloud GPU instance with the majority of that time devoted to training the classifier.

Example Scripts

The /examples directory contains command line scripts that can be run on an appropriate system. The scripts pull a Docker image from Docker Hub and then perform the processing on your camera trap image folder. For GPU support you need to use a current version of Linux or Windows 10/11. There are individual scripts to run each of the Docker images and a single script that will run all of the Docker images in sequence over a camera trap service. We provide example scripts for both Linux/Mac and Windows 10/11. You can find the bash scripts here and the PowerShell scripts here.

Docker Hub Images

The Docker images are automatically built and pushed to Docker Hub using GitHub Actions for CI/CD. We adhere to Semantic Versioning 2.0.0 and maintain version consistency bewtween GitHub and Docker Hub tags.

Docker Source Code

The source code below is unecessary if you just want to use the images. You can simply pull them from Docker Hub and use or modify one of the example scripts.

mewc-detect

This Docker image contains the MegaDetector models md_v4.1.0.pb, md_v5a.0.0.pt and md_v5b.0.0.pt and is based on PyTorch 1.11.0, CUDA 11.3 and CUDNN8. Additionally it has TensorFlow to support MD4.1 and GPU support.

mewc-snip

This Docker image is used to snip and save detections from a MegaDetector output JSON file and the original camera trap images.

mewc-train

This Docker image is used to train an EfficientNetV2 model. It is based on TensorFlow, CUDA and CUDNN8. The container is configured to use a GPU if available.

mewc-predict

This Docker image is used to predict the class of camera trap images using an EfficientNetV2 model. It is based on TensorFlow, CUDA and CUDNN8. The container is configured to use a GPU if available.

mewc-exif

This Docker image is used to write the class of camera trap images to the EXIF metadata. This is useful for sorting images based on class in camertrap database programs like Camelot.

mewc-box

This Docker image is used to draw bounding boxes on camera trap images using detections from a MegaDetector output JSON file. Additionally it will sort the original camera trap images into folders based on the MegaDetector detection type (human, animal, vehicle, blank).

Docker Base Images

The base images are used to build the Docker images above. They are not intended to be used directly.

mewc-flow

A Docker base image that include TensorFlow, CUDA and CUDNN. It is used for EfficientNetV2 training and inference.

mewc-torch

A Docker base image to suppor the MegaDetector Docker image. It also supports mewc-snip and mewc-box which use the MegaDetector utility libraries.

Docker Infrastrcture Ultilities

These Docker images are intended to be used as a toolset for building infrastructure in the cloud. You need to clone the repository and build the images locally as the code is directly used for Terraform plans and Ansible playbooks.

mewc-infrastructure

A Docker image that contains Terraform, Ansible and OpenStack for Nectar Research Cloud infrastructure deployment. You will need to carefully read the README.md file in the repository to understand how to use this image.
