I am a PhD Student at the Computer Vision Lab of ETH Zurich and CSEM under the supervision of Prof. Luc Van Gool. I am also advised by Dr. Martin Danelljan and Prof. Radu Timofte. I have an advanced master’s degree in Artificial Intelligence from KULeuven, Belgium, and an Electrical and Computer Engineering diploma from the National Technical University of Athens
These days I occupy myself with tasks revolving around generating and manipulating images. I am particularly interested in finding out how we can control this process while retaining high perceptual quality.

Positional encodings have enabled recent works to train a single adversarial network that can generate images of different scales. However, these approaches are either limited to a set of discrete scales or struggle to maintain good perceptual quality at the scales for which the model is not trained explicitly. We propose the design of scale-consistent positional encodings invariant to our generator’s layers transformations. This enables the generation of arbitrary-scale images even at scales unseen during training. Moreover, we incorporate novel inter-scale augmentations into our pipeline and partial generation training to facilitate the synthesis of consistent images at arbitrary scales. Lastly, we show competitive results for a continuum of scales on various commonly used datasets for image synthesis.
