Extract roads from satellite images
For this problem, we provide a set of satellite/aerial images acquired from GoogleMaps. We also provide ground-truth images where each pixel is labeled as {road, background}. Your goal is to train a classifier to segment roads in these images, i.e. assign a label {road=1, background=0} to each pixel. Please see detailed instructions on the course github.
Dataset
File descriptions
See Resources section:
- training.zip - the training set consisting of images with their ground truth
- test_set_images.zip - the test set
- sampleSubmission.csv - a sample submission file in the correct format
- mask_to_submission.py - script to make a submission file from a binary image
- submission_to_mask.py - script to reconstruct an image from the sample submission file
The sample submission file contains two columns:
-
The first column corresponds to the image id followed by the x and y top-left coordinate of the image patch (16x16 pixels)
-
The second column is the label assigned to the image patch
Evaluation
Your algorithm is evaluated according to the following criterion:
- F1 score (this combines the two numbers of precision and recall)
Rules
Each participant is allowed to make 5 submissions per day. If you particpate as a team, the whole team gets 5 submissions, not 15 as the rules page states. Failed submissions (e.g. wrong submission file format) do not count.
