Abstract

This study shows a preliminary investigation of shadow detection in drone-acquired images using a deep learning method with minimal labelled shadow images. The aim is to discuss how the selected U-Net architecture performs in a small-sized dataset consisting of various types of shadow brightness and objects. Two types of data augmentation methods, which are shadow variant and geometric transformation are implemented, aiming to improve the segmentation accuracy. Several experimental procedures are performed to observe the model performance. The study shows that adding images for training increases the accuracy of shadow detection in drone images from 0.95 to 0.96, and geometric transformation data augmentation method increases the accuracy from 0.961 to 0.963, while the shadow variant method increases the flexibility of detection.
