However, data protection regulations in Europe require that individuals’ data should be processed in such a way that the individual cannot be identified from the collected data. Therefore, before camera images taken from test vehicles save on a server, license plates and faces of individuals should be anonymized first. Nevertheless, the impact of using anonymized data on the performance of machine learning algorithms remains unclear. Our work aims to evaluate the impact of anonymization on the task of semantic segmentation using diverse neural network architectures, a range of input image resolutions, and different anonymization patterns. We observe statistically significant effects of anonymizing image data on model performance and investigate methods for mitigating segmentation precision loss.enImage segmentationMachine learning algorithmsIntelligent vehiclesSemanticsNeural networksTraining dataLicensesconference paper
