Species Recognizer

Introduction

What is Species Recognizer?

The "Species Recognizer" is a Deep Neural Network-based model trained using the YOLO (You Only Look Once) algorithm, leveraging the COCO (Common Objects in Context) dataset. This model is designed to accurately detect and classify various objects within an image, covering a wide range of categories such as animals, vehicles, furniture, and more.

Applications of Species Recognizer

The "Species Recognizer" is versatile and can be applied across multiple domains, including wildlife conservation, agriculture, environmental monitoring, and more. Its real-time object detection capability makes it invaluable for various industries.

Literature Survey

Object detection algorithms have evolved significantly, moving from traditional region proposal methods to modern deep learning-based approaches like YOLO. YOLO divides images into a grid and directly predicts bounding boxes and class probabilities, offering efficient and real-time object detection. The COCO dataset is a critical resource, providing a vast array of images covering 80 different object categories, essential for training and evaluating these models.

Researchers have explored applying these techniques to species recognition, addressing challenges like variability in species appearance and environmental conditions. Integrating OpenCV with YOLO has further optimized image preprocessing, improving object detection performance. Hyperparameter optimization is crucial for enhancing model accuracy, particularly for species recognition tasks.

Real-world applications span various domains, and despite challenges like dataset biases and domain adaptation, future research continues to advance object detection technologies for species recognition.

Problem Statement

The objective is to develop an efficient and accurate system capable of automatically identifying and classifying species of interest in images or video streams using YOLO and COCO.

Tools and Technologies

Visual Studio Code

Visual Studio Code (VS Code) served as the primary IDE, offering a versatile and efficient platform for writing, debugging, and managing code.

Python Programming Language

Python was the core programming language used, with several key libraries integrated into the project:

  • OpenCV: Used for image preprocessing tasks such as resizing, normalization, and noise reduction.
  • NumPy: Facilitated efficient numerical computations and data manipulation.
  • Flask: Enabled the development of the web application framework, creating RESTful APIs for communication between frontend and backend components.

Frontend Technologies

  • HTML, JavaScript, CSS: These technologies were used to design and enhance the user interface of the application.

Docker

Docker was employed for containerization, allowing for easy deployment and scalability of the application across different environments.

Project Working

The implementation of the YOLO algorithm alongside the COCO dataset has significantly advanced our ability to perform real-time object detection and classification. OpenCV was used for image preprocessing, ensuring the model received high-quality input data. The model, using pre-trained weights fine-tuned for its performance, accurately predicts the classes of objects in input images, showcasing exceptional accuracy and efficiency.

Loading the YOLO Network

To load the YOLO network, you will need three key files:

  1. coco.names - Contains the names of the object classes.
  2. yolov3.cfg - The configuration file that defines the YOLO architecture.
  3. yolov3.weights - The pre-trained YOLO weights. You can download it here (237 MB).

Running the Project

Running Locally (Without Docker)

  1. Ensure you have Python, OpenCV, and Flask installed on your device.
  2. Navigate to the project folder using the CLI.
  3. Run one of the following commands to start the application: 
    flask run
    -or- 
    python app
    -or- 
    py -3.12 -m app
    (Use the last command if you have multiple Python versions and want to specify version 3.12).

Running with Docker

  1. Navigate to the folder where the project files are located.
  2. Run the following commands in PowerShell or Command Prompt to build the Docker image and container: 
    docker build . -t species-recognition:v1
docker container run -d -p 5000:5000 species-recognition:v1
    Ensure you have Docker installed by checking the version with docker -v.
  3. Open localhost:5000 in your browser, or manage the container via Docker Desktop.
