Dog Breed Classifier Capstone Project

Project Overview

This project aims to build a pipeline that can be used within a web or mobile app to process real-world, user-supplied images. Given an image of a dog, our algorithm identifies an estimate of the canine’s breed. If supplied an image of a human, the code identifies the resembling dog breed.

Along with exploring state-of-the-art CNN models for classification and localization, this project aims to highlight the challenges involved in piecing together a series of models designed to perform various tasks in a data processing pipeline. Each model has its strengths and weaknesses, and engineering a real-world application often involves solving many problems without a perfect answer.

Dependencies

This project mainly makes use of Python, Jupyter Notebooks, OpenCV and PyTorch. Other packages used in this project have been listed in the requirements.txt file and may be installed following the instructions in the Project Instructions section.

Project Instructions

To manually run through the code, you may either follow the instructions given below to run the code locally, or you may simple follow this URL to open the notebook on Google Colab: https://bit.ly/3hFjpC3

Instructions

1. Clone the repository and navigate to the downloaded folder.

   	git clone https://github.com/aaakashkumar/Dog-Breed-Classifier.git
   	cd deep-learning-v2-pytorch/project-dog-classification
   

2. Download the dog dataset. Unzip the folder and place it in the repo, at location path/to/dog-project/dogImages. The dogImages/ folder should contain 133 folders, each corresponding to a different dog breed.

3. Download the human dataset. Unzip the folder and place it in the repo, at location path/to/dog-project/lfw. If you are using a Windows machine, you are encouraged to use 7zip to extract the folder.

4. Install the necessary Python packages

   pip install -r requirements.txt
   

5. Open a terminal window and navigate to the project folder. Open the notebook and follow the instructions.
