Summary: | In this paper, we demonstrate a self-supervised deep learning pipeline that can effectively learn to detect vehicles without using any pre-labeled training data. The pipeline uses a morphological vehicle detection algorithm to automatically generate training sets for a convolutional neural network (CNN). We tested this methodology on a mixed-use urban neighborhood in Riyadh, Saudi Arabia using 0.31-meter multispectral Worldview-3 satellite imagery with eight bands in the visible and near-infrared wavelengths. This method leverages the class imbalance inherent to many vehicle detection problems by generating a balanced training sample from a high-precision, low-recall morphological model to train a neural network to identify general vehicle characteristics. This approach is built on broadly applicable image processing methods and, with appropriate adjustments, might be adapted to high-resolution from various satellite or aerial sources. |
