Flower Species Recognition System

alt text

This repo contains the code for conference paper titled Flower Species Recognition System using Convolutional Neural Networks and Transfer Learning, by I.Gogul and V.Sathiesh Kumar, Proceedings of ICSCN-2017 conference, IEEE Xplore Digital Library.

Summary of the project

  • Pretrained state-of-the-art neural networks are used on University of Oxford's FLOWERS17 and FLOWERS102 dataset.
  • Models used - Xception, Inception-v3, OverFeat, ResNet50, VGG16, VGG19.
  • Weights used - ImageNet
  • Classifier used - Logistic Regression
  • Tutorial for this work is available at - Using Pre-trained Deep Learning models for your own dataset

Update (16/12/2017): Included two new deep neural net models namely InceptionResNetv2 and MobileNet.
