High-quality computer graphics, with their ubiquitous presence in games, illustrations, and visualization, are considered state-of-the-art in visual display technology.

The method used to render high-quality and realistic images is known as “path tracing,” which makes use of a Monte Carlo (MC) denoising approach based on supervised machine learning. In this learning framework, the machine learning model is first pre-trained with noisy and clean image pairs and then applied to the actual noisy image to …
