Semantic Segmentation Project (Advanced Deep Learning)

introduction

The goal of this project is creating the model of fully convolutional neural network which identify the space of the road in an image feed to network.

Approach

Architecture

For construct fully convolutional neural network, pre-trained VGG16 network is used.
The output of this pre-trained network is converted to 1x1 convolutional layer and feed to next convolutional transpose layer.
And for improvement of performance, 1x1 convolution of layer4 is added.
And then to construct next layer, convolutional transpose is used and 1x1 convolution of layer3 is added.
And next transpose convolutional layer is final output. In each layer, kernel initializer and regularizer is used.

loss function

To generate loss, soft max cross entropy is used.
And in training, adam optimizer is used for optimize.

Training

The hyperparameters used for training are:
keep_prob: 0.5
learning_rate: 0.0009
epochs: 50
batch_size: 5

Result

At epoch 50, The loss becomes about 0.032 to 0.015.

The following is from the original Udacity repository README

Introduction

In this project, you'll label the pixels of a road in images using a Fully Convolutional Network (FCN).

Setup

Frameworks and Packages

Make sure you have the following is installed:

Dataset

Download the Kitti Road dataset from here. Extract the dataset in the data folder. This will create the folder data_road with all the training a test images.

Start

Implement

Implement the code in the main.py module indicated by the "TODO" comments. The comments indicated with "OPTIONAL" tag are not required to complete.

Run

Run the following command to run the project:

python main.py

Note If running this in Jupyter Notebook system messages, such as those regarding test status, may appear in the terminal rather than the notebook.

Submission

  1. Ensure you've passed all the unit tests.
  2. Ensure you pass all points on the rubric.
  3. Submit the following in a zip file.
  • helper.py
  • main.py
  • project_tests.py
  • Newest inference images from runs folder (all images from the most recent run)
