Overview

  • There are five classes.
    NameLabel =  {construction: 0, crowd: 1, pothole: 2, person-bike: 3, person-pet: 4}
    
  • Images are 96×96 pixels, color.
  • 50K images, each class has 10K images.
  • Images are acquired from taking pictures from the sidewalk and from the google image search.

How to load in python

The data file is available in python pkl format.

import pickle
def load_file(filename):
    '''Load the sidewalk obstacle image data'''
    with open(filename, 'rb') as f:
        datadict= pickle.load(f)
        (X_train,Y_train),(X_valid,Y_valid),(X_test,Y_test) = datadict
    	return (X_train, Y_train),(X_valid,Y_valid),(X_test,Y_test)


# load training, validation and test set 
train,valid,test = load_file('sidewalk_rgb_all.pkl')

# separate the features and label 
X_train,y_train = train
X_valid,y_valid = valid
X_test, y_test  = test
