1. Introduction

There are 4 prominent computer vision tasks:

  1. Image Classification
  2. Object Detection
  3. Semantic Segmentation
  4. Instance Segmentation

This post shows an example of Semantic Segmentation. We will use the Oxford-IIIT Pet Dataset.

The dataset consists of a 37 category dog and cat pet dataset with roughly 200 images for each class. The images have large variations in scale, pose and lighting. All images have an associated ground truth annotation of breed, head ROI, and pixel level trimap segmentation. We will make use of the trimap segmentation pixel labels.

To perform the training and deployment of our semantic segmentation model we will make use of Amazon SageMaker. SageMaker provides a seamless pipeline.

2. Platform Setup

This notebook should be run on a 'notebook instance' which could be setup within the SageMaker service.

!pip3 install tqdm
!pip3 install pillow --upgrade

Requirement already satisfied: tqdm in /home/ec2-user/anaconda3/envs/amazonei_mxnet_p36/lib/python3.6/site-packages (4.60.0)
Requirement already satisfied: pillow in /home/ec2-user/anaconda3/envs/amazonei_mxnet_p36/lib/python3.6/site-packages (8.2.0)

3. Get Data 

# setup folders on the notebook instance/VM
if not os.path.isdir('data'):
    os.mkdir('data')

urls = ['http://www.robots.ox.ac.uk/~vgg/data/pets/data/images.tar.gz',
        'http://www.robots.ox.ac.uk/~vgg/data/pets/data/annotations.tar.gz']

def download_and_extract(data_dir, download_dir):
    for url in urls:
        target_file = url.split('/')[-1]
        if target_file not in os.listdir(download_dir):
            urllib.request.urlretrieve(url, os.path.join(download_dir, target_file))
            tf = tarfile.open(url.split('/')[-1])
            tf.extractall(data_dir)
            print(f'{url} downloaded and extracted ...', )
        else:
            print('Already downloaded', url)

download_and_extract('data', '.')

4. Inspect Data

We will use the following convention for naming data objects:

  • x: train data
  • y: label data
  • yh: predicted data ('h' is for 'hat')
y_fold = 'data/annotations/trimaps/'
ys = [img for img in os.listdir(y_fold) if img[-3:] == 'png']
print(len(ys))

14780

x_fold = 'data/images/'
xs = [img for img in os.listdir(x_fold) if img[-3:] == 'jpg']
print(len(xs))

7390

xs[7]

'scottish_terrier_88.jpg'
num_examples = 5
plt.figure(figsize=(15, 15))
for i in range(0, num_examples):
    ix = random.randint(0, len(xs) - 1)
    x_name = xs[ix]
    y_name = xs[ix].split('.')[0] + '.png'

    plt.subplot(num_examples, 2, 1 + i*2)
    plt.xticks([])
    plt.yticks([])
    plt.imshow(plt.imread(os.path.join(x_fold, x_name)))
    
    plt.subplot(num_examples, 2, 2 + i*2)
    plt.xticks([])
    plt.yticks([])
    plt.imshow(plt.imread(os.path.join(y_fold, y_name)))

ys[10]

'english_cocker_spaniel_173.png'
# unique values in a label map
img = Image.open(os.path.join(y_fold, ys[10]))
print(np.unique(img))

6. Split Data into train/valid 

folders = ['train', 'train_annotation', 'validation', 'validation_annotation']
for folder in folders:
    if os.path.isdir(folder):
        shutil.rmtree(folder)
    os.mkdir(folder)

    return map_file

    image_target_path = os.path.join(target_set, image)
