Plant Disease Detection Web Application using Fastai

Achieving state of the art result with fast.ai

Introduction

Creating an AI web application that detects diseases in plants using FastAi which built on the top of Facebook’s deep learning platform: PyTorch. According to the Food and Agriculture Organization of the United Nations (UN), transboundary plant pests and diseases affect food crops, causing significant losses to farmers and threatening food security.

Achieved 99.654% Accuracy with Resnet34 model

Motive

For this challenge, I used the “PlanVillage” dataset. This dataset contains an open access repository of images on plant health to enable the development of mobile disease diagnostics. The dataset contains 54, 309 images. The images span 14 crop species: Apple, Blueberry, Cherry, Grape, Orange, Peach, Bell Pepper, Potato, Raspberry, Soybean, Squash, Strawberry, and Tomato. It contains images of 17 fundal diseases, 4 bacterial diseases, 2 molds (oomycete) diseases, 2 viral diseases, and 1 disease caused by a mite. 12 crop species also have images of healthy leaves that are not visibly affected by a disease.
