Alternative Data Augmentation for Industrial Monitoring using Adversarial Learning

no code implementations9 May 2022 Silvan Mertes, Andreas Margraf, Steffen Geinitz, Elisabeth André

However, a precise examination of the resulting images indicate that WGAN and image-to-image translation achieve good segmentation results and only deviate to a small degree from traditional data augmentation.

Dynamic Difficulty Adjustment in Virtual Reality Exergames through Experience-driven Procedural Content Generation

no code implementations19 Aug 2021 Tobias Huber, Silvan Mertes, Stanislava Rangelova, Simon Flutura, Elisabeth André

As a proof-of-concept, we implement an initial prototype in which the player must traverse a maze that includes several exercise rooms, whereby the generation of the maze is realized by a neural network.
