Nisansa Dilushan de Silva

I am a lecturer at the Department of Computer Science & Engineering, University of Moratuwa, Sri Lanka. I obtained my Ph.D (2020, advisor: Dejing Dou) and MS (2016) degrees in Computer and Information Science from University of Oregon, USA and my BSc (Hons) in Computer Science & Engineering (2011) degree from University of Moratuwa. I joined University of Moratuwa as a lecturer in 2011. From 2013 to 2014, I worked as a researcher at LIRNEasia. In 2018, I worked as a Givens Associate at Argonne National Laboratory, USA. I have over 80 peer reviewed publications in the field of computer science, mostly under the subfields of Natural Language Processing and Artificial Intelligence, earning more than 1400 citations. I am also an associate member of the IESL.

A Multi-Stage Approach to Image Consistency in Zero-Shot Character Art Generation for the D\&D Domain


G. Weerasundara, and N. de Silva

Proceedings of the 16th International Conference on Agents and Artificial Intelligence - Volume 3: ICAART, INSTICC, 2024, pp. 235-242,

In the evolving landscape of computer graphics, the pursuit of consistency in image generation remains a compelling challenge. This paper delineates a comprehensive methodology that harnesses the capabilities of the Stable Diffusion (SD) model, an adept open-source image generation tool, to generate consistent and high-fidelity imagery. Beginning with the training of a generalized art style for the popular tabletop role-playing game Dungeons and Dragons, our research journeyed through specific character generation and the creation of exhaustive character sheets, culminating in the generation of consistent character images across various poses.
