DOTA-C

This repository introduces a few image corruptions for two novel benchmarks to evaluate models' robustness in aerial object detection. All these corruptions are applied to DOTA-v1.0 test set and not used as data augmentation strategies in models' training phase.

Corruptions form ImageNet-C

The first benchmark encompasses 19 prevalent corruptions. For more detailed information, you may refer to the paper on the original corruption package authored by Hendrycks and Dietterich: Benchmarking neural network robustness to common corruptions and perturbations.

Clouds

The second benchmark focuses on cloud-corrupted images—a phenomenon uncommon in natural pictures yet frequent in aerial photography. Process 1 represents "Cloud Self-Subtraction" and process 2 represents "Cloud Addition-to-Scene". The detailed principle of this data processing method can be referred to Cloudy Image Arithmetic: A Cloudy Scene Synthesis Paradigm With an Application to Deep-Learning-Based Thin Cloud Removal.

Models' Results

Note that, unless explicitly stated, the backbone of all models is ResNet-50.
