ICMLA2019 OCT_Classification

PWC PWC

A model for classifying different Retinal Diseases using Deep Learning from Optical Coherence Tomography Images. This code is part of the supplementary materials for the IEEE ICMLA 2019 for our paper Optic-net: A Novel Convolutional Neural Network for Diagnosis of Retinal Diseases from Optical Tomography Images. The paper has since been accpeted to IEEE ICMLA 2019 and will be preseneted in December 2019.

Folder Structure Rearrangement

  • The folder stucture for this dataset needs to be rearranged. We have provided a .py file to rearrange the structure and also, create the necessary directories and sub-directories. Please run the python file data_preprocess_sri2014.py. In cmd/terminal type the below command. Run it as it is or tinker with it, if you wanna change the directory.
python3 data_preprocess_sri2014.py
  • The structure will look like this before the rearrangement.
