RADiff: Controllable Diffusion Models for Radio Astronomical Maps Generation

no code implementations5 Jul 2023 Renato Sortino, Thomas Cecconello, Andrea DeMarco, Giuseppe Fiameni, Andrea Pilzer, Andrew M. Hopkins, Daniel Magro, Simone Riggi, Eva Sciacca, Adriano Ingallinera, Cristobal Bordiu, Filomena Bufano, Concetto Spampinato

We evaluate the effectiveness of this approach by training a semantic segmentation model on a real dataset augmented in two ways: 1) using synthetic images obtained from real masks, and 2) generating images from synthetic semantic masks.

Transformer-based Image Generation from Scene Graphs

1 code implementation8 Mar 2023 Renato Sortino, Simone Palazzo, Concetto Spampinato

In this work, we show how employing multi-head attention to encode the graph information, as well as using a transformer-based model in the latent space for image generation can improve the quality of the sampled data, without the need to employ adversarial models with the subsequent advantage in terms of training stability.

Transforming Image Generation from Scene Graphs

no code implementations1 Jul 2022 Renato Sortino, Simone Palazzo, Concetto Spampinato

Generating images from semantic visual knowledge is a challenging task, that can be useful to condition the synthesis process in complex, subtle, and unambiguous ways, compared to alternatives such as class labels or text descriptions.
